| Features Prod Apps's expert score for the 'Features' aspect of each app. | 7.0 Cool VPN Pro offers a respectable feature set that covers the essentials of VPN functionality. The app advertises thousands of servers across multiple countries, which is competitive for this price range. The ability to automatically connect based on network type (Wi-Fi or cellular) adds convenience for users who want constant protection. The app-specific VPN routing stands out, letting you choose which applications use the VPN connection while others access the internet directly. This flexibility proves useful when you need VPN protection for specific apps but want normal speeds for others. The one-tap connection interface makes getting online quick—when it works properly. The feature set feels somewhat basic compared to premium competitors. Split-tunneling for websites is absent, server information is limited, and the selection process lacks granularity. Detailed connection statistics and advanced security options that power users expect are missing. The promised "unparalleled VPN performance" in the app description doesn't match what users actually experience. The core VPN features are present, but execution has become inconsistent. Advertised features like "one-tap connection" now frequently result in extended "network optimization" screens that never resolve. Reliability is a feature in itself for VPN apps, and Cool VPN Pro's recent struggles here significantly impact the overall rating. | 8.0 Calm's content library is genuinely impressive and sets the standard for meditation apps. The celebrity-narrated sleep stories are the standout feature—falling asleep to Cillian Murphy's voice, Bob Ross painting descriptions, or Rosé's calming narration provides a unique experience users rave about. These aren't just celebrity gimmicks; they're high-quality productions that genuinely help people fall asleep. Outstanding features include:
The library is genuinely extensive, with enough variety that most users find multiple favorites. The quality is consistently high—professional voice work, good production values, and thoughtful content design. Users frequently mention specific favorites like "Painting with Bob Ross" or programs with Tamara Levitt that they return to regularly. The app uses a subscription model, with most content requiring payment. The free version offers limited access, which is standard for premium apps in this category. Some users wish for more free content to evaluate before subscribing, though the free trial provides opportunity to explore the library. A few long-term subscribers mention content updates could be more frequent, though the existing library is large enough that most users have plenty to explore. For daily users who cycle through content quickly, occasional waits for new stories can be noticeable. We're rating features 8.0 out of 10. The celebrity sleep stories, daily programs, and extensive meditation library provide excellent value, making Calm a feature-rich leader in the meditation app category. Winner in this category |
| Performance Prod Apps's expert score for the 'Performance' aspect of each app. | 4.5 Performance is where Cool VPN Pro's current struggles become most apparent. The app's overall 4.8-star rating tells one story, but the recent 3.86-star average from the last 100 reviews tells another. This significant drop reflects widespread performance issues that have emerged recently. Connection reliability is the primary concern. Numerous recent reviews report that the app gets stuck on "network optimization" screens and fails to establish connections. Some users mention waiting 10 minutes or more for connections that never complete. Others report that the app simply "doesn't work" at all, despite previously functioning normally. This inconsistency is particularly problematic for a VPN service where reliability is paramount. When connections do establish, speed performance is mixed. Some users report adequate speeds for browsing and streaming, with one reviewer praising "blazing fast, unlimited speed." However, an equal number complain about extremely slow connections—one user described speeds of "3 kbit per second," which is essentially unusable. This wide variance suggests inconsistent server quality or capacity issues. The app's stability has also deteriorated. Multiple reviews mention increased crashes, freezing, and unexpected disconnections. Battery drain is mentioned by several users, suggesting the app may not be efficiently managing system resources. The long loading times and "optimization progress not ended" errors indicate potential server-side or network infrastructure problems that the developers haven't adequately addressed. Server availability appears inconsistent as well, with some users reporting that "all servers are down" during their attempts to connect. While it works reliably for some users (particularly those in certain regions like Iran and Myanmar where it remains popular), the overall performance trajectory is concerning. For a VPN service at any price point, the level of connection failures and performance issues we've documented is difficult to justify. | 7.5 Calm performs reliably for the vast majority of users across 50+ million downloads and two platforms. The 4.8-star iOS rating and 4.1-star Android rating indicate consistent, stable performance that users depend on nightly. Audio playback is smooth, sleep stories run without interruption, and the app handles background playback well while you sleep. Performance strengths:
The app handles demanding use cases well—playing audio continuously through 7-8 hours of sleep, managing large content libraries, and supporting offline downloads. Users who've used Calm for years mention it working consistently night after night, which demonstrates solid long-term reliability. A small percentage of users report occasional audio stopping during sleep sessions or rare app crashes. These issues seem device or configuration-specific rather than widespread problems, as the majority of users don't mention performance concerns. Some users note the splash screen takes a moment to dismiss, though this is designed as a brief mindfulness moment rather than a technical delay. Load times are generally good, with content starting quickly after selection. The app's size and resource usage are reasonable for the extensive content library it manages. Updates are regular, suggesting active maintenance and performance optimization. For an app with 50M+ downloads used nightly by millions, achieving 4.8 stars on iOS demonstrates exceptional performance reliability. The vast majority of users experience smooth, consistent operation exactly when they need it most—during meditation and sleep. We're rating performance 7.5 out of 10. Calm delivers reliable, stable performance for the overwhelming majority of users, with consistent playback and efficient resource usage. The high ratings across millions of users demonstrate performance excellence at scale. Winner in this category |
| Design Prod Apps's expert score for the 'Design' aspect of each app. | 6.5 The design of Cool VPN Pro follows a fairly standard VPN app layout with a prominent connection button as the centerpiece. The interface is straightforward with minimal distractions, which makes it approachable for users who aren't technically savvy. The color scheme is simple, and the main connection status is clearly visible. Navigation between servers and settings is uncomplicated, with most options accessible within a few taps. The server list is organized by country with flags for easy identification, and connection status indicators use familiar colors (red for disconnected, green for connected). This conventional approach works well enough for basic functionality. However, the design feels dated compared to modern VPN apps like NordVPN or ExpressVPN, which have invested heavily in polished, intuitive interfaces. The visual hierarchy could be improved, and some screens feel cluttered with promotional content for premium features. The design lacks the sophistication and attention to detail that makes premium apps feel premium. The biggest design issue is the intrusive advertisement placement in the free version. Multiple users complain about ads appearing at inconvenient moments, disrupting the user experience. While monetization through ads is understandable, the implementation here feels aggressive and detracts from the overall design quality. | 7.5 Calm's design successfully creates a soothing, peaceful atmosphere that supports its meditation and sleep mission. The dark, calming color scheme with deep blues and purples sets the right mood immediately. Visual elements are thoughtfully chosen to promote relaxation rather than stimulation, which is exactly what you want from a meditation app. Design strengths:
The interface generally succeeds at fading into the background, letting the content take center stage. For most users, navigation feels natural—open the app, select your content, and start your meditation or sleep session without friction. Some users mention the splash screen "take a breath" message appears frequently and takes a moment before you can access content. While this fits the app's philosophy, a few long-term subscribers find it repetitive after daily use for years. The search function within categories could be more robust for power users who want to explore the full catalog depth. For subscribers, the experience is streamlined. For free users exploring before committing, distinguishing between free and premium content could be clearer, though this is fairly standard for freemium apps. We're rating design 7.5 out of 10. Calm delivers a beautiful, calming visual experience with thoughtful design that supports meditation and sleep. Minor navigation refinements would elevate it further, but the overall aesthetic excellence justifies the premium positioning. Winner in this category |
| Value for Money Prod Apps's expert score for the 'Value for Money' aspect of each app. | 5.0 Cool VPN Pro's value proposition is complicated. The free tier exists, which technically makes it accessible to anyone, but the ad-heavy experience and limited server access mean you're getting what you pay for—or less. Based on user feedback, the free version has become increasingly restricted and difficult to use without constant ad interruptions. The premium pricing (€2.69 to €104.99) sits below what you'd pay for premium services like ExpressVPN, making it appear competitive. However, value isn't just about the price—it's about what you receive for that price. With Cool VPN Pro's declining reliability and increasing connection issues, the question becomes whether saving a few euros monthly is worth the frustration of a VPN that doesn't consistently work. Users who subscribed when the service was more reliable express disappointment with recent performance degradation. Several reviews mention that "it was wonderful when it was free" or that the service has declined since they first started using it. This suggests that the value equation has shifted negatively over time, with the company perhaps struggling to maintain service quality as it scales. Compared to Brave Private Browser's integrated VPN features or even AVG Secure VPN's straightforward offering, Cool VPN Pro doesn't clearly differentiate itself on value. The extensive advertisements, reliability issues, and lack of transparency about server quality make it difficult to recommend as a strong value option, even at its lower price point. If you need a VPN that consistently works, spending a bit more on a proven service might ultimately provide better value. | 7.0 At around €70 per year (pricing varies by region), Calm positions itself as a premium meditation app, and for most users, the content library justifies the investment. With 50M+ downloads and 4.8 stars on iOS, millions of people clearly find value worth paying for. Users who've subscribed for years mention the app becoming an essential nightly routine they wouldn't want to give up. The value proposition is strong:
For users getting Calm through employer wellness programs, the value is excellent—high-quality content at no personal cost. Even at full price, long-term subscribers frequently mention the subscription has become essential for their sleep quality and mental health, which makes the cost worthwhile. The subscription model is standard for premium apps—the free version offers limited access to encourage paid subscription. Users can try the app during a free trial period to evaluate whether the content works for them before committing long-term. Cancellation through the Play Store is typically one-click, which most users navigate successfully. Some users report billing confusion during trial periods or difficulty with customer service responses when issues arise. A small number mention pricing discrepancies during promotional periods. Like any subscription service, it's important to track trial end dates and verify charges match promotional pricing if taking advantage of special offers. Compared to competitors, Calm sits at the premium end with Headspace, while Medito offers free content. The celebrity narrations and production quality differentiate Calm's value proposition. We're rating value for money 7.0 out of 10. The extensive, high-quality content library with unique celebrity narrations provides solid value for the subscription price, particularly for users committed to regular meditation and sleep improvement. Those with employer coverage get excellent value, and even full-price subscribers generally find the cost justified by daily use. Winner in this category |
| Ease of Use Prod Apps's expert score for the 'Ease of Use' aspect of each app. | 6.0 When Cool VPN Pro works as intended, it's reasonably easy to use. The basic concept is simple: open the app, tap the connect button, and you're protected. For users who just want to bypass regional restrictions without diving into technical settings, the straightforward approach has merit. First-time users can get connected without reading documentation or watching tutorials. The app provides some helpful automation features, like the option to auto-connect when joining specific networks. Setting these up is relatively intuitive, and they work reliably once configured. Server switching is straightforward, with a simple list interface that lets you select your desired location quickly. However, ease of use breaks down when things don't work smoothly. A significant number of recent reviews mention getting stuck on loading screens, particularly the "network optimization" phase. When connection attempts fail, error messages are often vague and don't provide actionable solutions. This creates frustration, especially for less technical users who don't know how to troubleshoot VPN connection issues. The free version's ad interruptions also impact usability. Users report that ads appear when trying to connect or switch servers, adding friction to what should be a seamless process. Additionally, the distinction between free and premium features isn't always clear upfront, leading to confusion when certain servers or options are locked behind the paywall. | 7.0 Calm is designed to be intuitive, and for most users, it succeeds. Opening the app and starting a meditation or sleep story takes just a few taps. The main interface presents your options clearly—browse by category, check out daily programs, or jump back to recently played content. Playback controls are simple and work as expected. For subscribers in their daily routine, the experience is smooth. Select your favorite sleep story, set a timer if desired, and drift off. The app remembers your preferences, making it easy to return to content you love. Many users mention using Calm nightly for years, which speaks to how well the basic experience works. Usability strengths:
The free trial process is standard for subscription apps—you provide payment information upfront, explore the content during the trial period, and can cancel before being charged. Most users navigate this successfully, though like any subscription app, you need to remember to cancel if you don't want to continue. Some users report specific issues: occasional login difficulties with Google authentication, confusion about which content is free versus premium for non-subscribers, and rare cases of the app stopping playback during the night. A small number of users mention subscription management confusion, though canceling through the Play Store is typically straightforward with one-click unsubscribe. The splash screen appears when opening the app, which some daily users find repetitive over time. For those who want to jump straight into content, this adds a brief delay, though it's designed to encourage that initial mindful breath. We're rating ease of use 7.0 out of 10. The app is genuinely easy to use for the vast majority of users, with intuitive navigation and simple playback. Minor friction points exist, particularly for free users exploring content boundaries, but don't significantly impact the subscriber experience. Winner in this category |
| Security & Privacy Prod Apps's expert score for the 'Security & Privacy' aspect of each app. | 5.5 Cool VPN Pro claims a no-logs policy, stating it doesn't track or keep logs of user activities. The app advertises a "high safe encryption algorithm" for securing connections on public Wi-Fi. These are standard VPN privacy claims, but the lack of transparency about specific encryption protocols raises concerns. Unlike premium VPN services that undergo independent security audits and publish detailed transparency reports, Cool VPN Pro provides limited information about its security practices. The privacy policy exists but isn't as comprehensive or clear as what you'd find with established providers like NordVPN or ExpressVPN. There's no mention of independent audits or third-party verification of their no-logs claims. The app requires various permissions, which is normal for VPN functionality, but the privacy implications of the extensive ad network integration in the free version aren't clearly disclosed. When you're using a VPN partly for privacy, having multiple advertising SDKs tracking your behavior creates an inherent contradiction. Premium subscribers avoid this issue, but free users should be aware of the trade-off. The company is registered in Singapore (HOPE DEVE PTE. LTD.), which has reasonable data protection laws, but it's not in a jurisdiction known for strong privacy protections like Switzerland or Iceland. The lack of clear information about server ownership (owned vs. rented) and data handling practices makes it difficult to fully assess the privacy posture. For users primarily concerned with bypassing geo-restrictions rather than maximum privacy, these concerns may be less critical. | 7.0 Calm handles user data responsibly with standard privacy practices appropriate for a wellness app. The company partners with major employers and insurance providers, which requires meeting enterprise-level security and privacy standards. With 50M+ downloads and partnerships with Fortune 500 companies, Calm maintains professional data protection practices. Security and privacy strengths:
The app collects usage data to track your meditation progress, favorite content, and streaks—standard for any app with personalization features. This data helps improve your experience by remembering preferences and providing personalized recommendations. The privacy policy outlines what data is collected and how it's used. Financial transactions are processed through Google Play Store, which provides an additional layer of security and familiar payment infrastructure. The Play Store handles payment information rather than the app storing it directly, following best practices for subscription apps. For users concerned about mental health data privacy, Calm's meditation and sleep content choices represent personal information. The app's enterprise partnerships and scale suggest they take this responsibility seriously, though as with any wellness app, users should review the privacy policy to understand data handling. Some users report billing questions during trial periods, which is common across subscription apps and typically relates to understanding trial terms rather than security issues. Standard subscription management through the Play Store provides familiar cancellation options for most users. The lack of data breach reports across millions of users and years of operation demonstrates solid security practices. For a wellness app trusted by major corporations, maintaining strong security and privacy standards is essential to business partnerships. We're rating security & privacy 7.0 out of 10. Calm maintains professional privacy practices appropriate for a wellness app with enterprise partnerships, handles user data responsibly, and shows no history of security breaches across millions of users.

| Conclusion A summary of our findings and final thoughts for each app. | Cool VPN Pro finds itself at a crossroads. While it has built a substantial user base of over 10 million downloads and maintains a historically strong 4.8-star rating, the recent performance decline tells a different story. The sharp drop to 3.86 stars in the most recent 100 reviews reflects growing frustration with connection failures, excessive advertisements, and reliability issues that have emerged over time. For users primarily seeking to bypass internet restrictions in regions with heavy censorship, Cool VPN Pro still serves a purpose, particularly given its lower price point and accessibility through a free tier. The app works adequately for some users, especially those who successfully connect and maintain stable sessions. However, the inconsistent performance makes it difficult to recommend with confidence. The core issue is reliability. A VPN needs to work when you need it, and Cool VPN Pro increasingly fails this fundamental test. The frequent connection failures, long optimization delays, and server availability problems create an unpredictable experience. When you're paying for a service—even a budget one—you should expect consistent functionality. If you're considering Cool VPN Pro, we'd recommend exploring more established alternatives first. NordVPN and ExpressVPN cost more but deliver significantly better reliability and performance. Brave Private Browser offers integrated VPN features with better transparency, while AVG Secure VPN provides a straightforward, reliable option without the connection issues. The money saved on Cool VPN Pro's lower pricing may end up costing you more in time and frustration dealing with a service that doesn't consistently deliver on its promises. | Calm has earned its position as a leading meditation and sleep app with 50M+ downloads, 4.8 stars on iOS, and 4.1 stars on Android. The celebrity-narrated sleep stories are genuinely special—falling asleep to Cillian Murphy, Bob Ross, or Rosé provides a premium experience that justifies the subscription for millions of users. The daily programs, extensive meditation library, and variety of soundscapes create comprehensive value. Long-term subscribers frequently mention Calm becoming essential to their nightly routine, helping with sleep quality and stress management over years of use. The production quality is excellent, the content library is extensive, and the app performs reliably for the vast majority of users. For those whose employers provide Calm subscriptions as a wellness benefit, it's an excellent value proposition. Recent Android reviews show some concerns—the last 100 reviews average 3.04 stars, lower than the overall rating. Some users mention billing confusion during free trials, occasional technical issues, and customer service responsiveness questions. These issues appear to affect a subset of Android users rather than representing the typical experience, but they're worth noting. If you're considering Calm, the free trial lets you explore the content library to see if the sleep stories and meditation programs work for you. The celebrity narrations and production quality differentiate it from competitors. For daily meditation and sleep improvement, Calm delivers substantial value that users rely on over years. Alternative options include Medito for free meditation content with no subscription required, and Headspace for premium content with different stylistic approach. But Calm's unique celebrity content and extensive library make it a strong choice for those committed to meditation and sleep improvement. |
