| Features Prod Apps's expert score for the 'Features' aspect of each app. | 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. | 9.0 Proton VPN delivers an exceptional set of features that prioritize privacy and security over flashy functionality. The app's feature set is comprehensive and focused on providing genuine privacy protection, which aligns perfectly with its target audience of privacy-conscious users. Key features we found most valuable include:
Proton VPN excels in providing advanced privacy features that are typically only available in premium VPNs. The free tier offers unlimited bandwidth with no ads, which is exceptional in the VPN market. The premium features are genuinely useful and not just cosmetic add-ons. While the core features are excellent, some limitations affect the overall experience. The free tier has limited server locations, and some users report connection issues. However, these limitations are reasonable for a privacy-focused service. For users who need advanced privacy features, Proton VPN offers the most comprehensive solution available. Alternatives like NordVPN provide more server locations, while Thunder VPN offers a more user-friendly free experience. We rate features at 9.0 out of 10—excellent privacy-focused features with genuine value for privacy-conscious users. Winner in this category |
| Performance Prod Apps's expert score for the 'Performance' aspect of each app. | 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 | 7.0 Proton VPN's performance presents a mixed picture that reflects the challenges of maintaining a privacy-focused VPN service. While the app can deliver good connections when working properly, some users report performance issues that impact the overall experience. Performance strengths include:
However, some performance issues undermine the user experience:
User reviews reveal mixed experiences, with some users praising the app's performance while others report connection issues. The app's focus on privacy over performance may be impacting server quality and maintenance. For users seeking reliable performance, alternatives like NordVPN offer more consistent performance with better server maintenance, while Thunder VPN provides more user-friendly performance. We rate performance at 7.0 out of 10—good performance when working but some connection issues and speed limitations that impact the overall experience. |
| Design Prod Apps's expert score for the 'Design' aspect of each app. | 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. | 8.5 Proton VPN's design philosophy centers on functionality and privacy over flashy aesthetics, which works well for its target audience of privacy-conscious users. The interface is clean, professional, and focuses on providing clear information about privacy and security features. Design strengths we observed include:
The design experience is significantly better than competitors like Turbo VPN and Now VPN, with no advertising interruptions. Users consistently praise the app's clean interface and professional appearance, making it one of the most trustworthy-looking VPNs available. While the core interface design is excellent, some users find the interface less intuitive than more user-friendly alternatives. However, this is a minor issue compared to the overall design quality. For users who value a clean, professional interface, Proton VPN offers one of the best experiences available. Alternatives like Thunder VPN offer more user-friendly design, while NordVPN provides a more modern interface. We rate design at 8.5 out of 10—excellent design principles with professional aesthetics that inspire trust and confidence. Winner in this category |
| Value for Money Prod Apps's expert score for the 'Value for Money' aspect of each app. | 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. | 8.5 Proton VPN's value proposition is excellent for privacy-conscious users, offering a genuinely useful free service with no ads and comprehensive privacy protection. The app provides exceptional value for users who prioritize privacy over cost. Value strengths include:
The free tier's value is exceptional, offering unlimited bandwidth with no ads and comprehensive privacy protection. However, some limitations affect the overall value:
The premium pricing is higher than some competitors, but the Swiss-based privacy protection and independent audits justify the cost for privacy-conscious users. Premium VPN services like NordVPN offer more comprehensive features for similar pricing, while Thunder VPN provides a more user-friendly free experience. For users seeking genuine privacy protection, Proton VPN offers exceptional value. Alternatives like NordVPN provide more server locations, while Thunder VPN offers a more user-friendly free experience. We rate value for money at 8.5 out of 10—excellent value for privacy-conscious users with exceptional free tier and premium features that justify the cost. Winner in this category |
| Ease of Use Prod Apps's expert score for the 'Ease of Use' aspect of each app. | 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. | 7.5 Proton VPN provides good usability with its one-tap connection approach, though the interface is more complex than simpler alternatives. The core functionality is straightforward, but the advanced features require some technical knowledge to use effectively. Usability strengths include:
However, the ease of use is somewhat compromised by the complexity of advanced features. Some users find the interface less intuitive than more user-friendly alternatives, and the advanced privacy features require some technical knowledge to configure properly. While the core interface is generally easy to use, the complexity of advanced features may overwhelm casual users. For users seeking a truly simple VPN experience, alternatives like Thunder VPN offer a more user-friendly interface, while NordVPN provides a more intuitive experience. We rate ease of use at 7.5 out of 10—good core usability with professional interface, but complexity of advanced features may overwhelm casual users. Winner in this category |
| Security & Privacy Prod Apps's expert score for the 'Security & Privacy' aspect of each app. | 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. | 9.5 Proton VPN's security and privacy practices represent the gold standard in the VPN industry, offering exceptional protection that goes far beyond basic VPN services. The app's commitment to privacy and security is unmatched by competitors. Security strengths include:
Proton VPN excels in providing genuine privacy protection that goes beyond marketing claims. The Swiss-based privacy protection and independent audits provide unmatched transparency and trust.

| Conclusion A summary of our findings and final thoughts for each app. | 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. | Proton VPN represents the gold standard for privacy-focused VPN services, offering exceptional privacy protection with Swiss-based privacy laws and independent security audits. While the app delivers on its core promise of secure, private VPN access with no ads, some users report connection issues and speed limitations that may impact the overall experience. The app's exceptional popularity (50M+ downloads, 4.7-star rating) reflects genuine demand for privacy-focused VPN services, and many users do find value in its comprehensive privacy protection. However, the recent rating decline (4.7 to 4.04 in last 100 reviews) and increasing complaints about connection issues suggest that the service may be experiencing some technical challenges. For users who prioritize privacy over performance, Proton VPN provides the most comprehensive privacy protection available. For users seeking a more user-friendly VPN experience, Thunder VPN offers a more intuitive interface with better performance, while NordVPN provides more comprehensive features with better reliability. For those who prioritize privacy above all else, Proton VPN remains the best choice available. |
