| 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. Winner in this category | 7.0 Habit Diary offers a solid foundation of habit tracking features that cover the essential needs of most users. The app's core functionality includes customizable daily habits, progress tracking, and a unique 30-day challenge system that sets it apart from many competitors. What we found particularly effective during our testing:
However, there are some limitations that impact the overall feature score. The free version restricts the number of habits users can track, which several users found frustrating. Additionally, some advanced features like detailed analytics and custom widgets are locked behind the premium paywall. We also confirmed user reports that "the app does not appear to have any widgets" in the free version, and encountered the same Google backup problems that users report, with one user stating "i cant backup my account with google." Based on our testing and user feedback, we rate the features at 7.0 out of 10. The app delivers solid core functionality and some unique elements like the challenge system, but the freemium restrictions and limited free features prevent it from scoring higher.

| 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. | 6.5 Habit Diary performs exceptionally well in day-to-day use. The app is lightweight, launches quickly, and all interactions—such as marking completions, navigating between views, and customizing habits—are smooth and responsive. We encountered very few bugs or crashes, and the app remained stable even when tracking a large number of habits. User reviews echo this experience, with most people praising the app's reliability and speed. However, there are some performance considerations that impact our rating:
Overall, Habit Diary delivers a consistently fast and stable experience, both in our hands-on testing and according to the majority of user feedback. We rate its performance at 6.5 out of 10, acknowledging the app's solid technical foundation while noting that some premium features and external integrations could benefit from performance optimization.

| 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. | 8.5 Habit Diary presents a clean and modern design that prioritizes usability while maintaining visual appeal. The interface strikes a good balance between functionality and aesthetics, with a layout that makes navigation intuitive for most users. Design strengths we observed include:
However, there are some design aspects that could be improved. The free version's ad integration can feel intrusive and disrupt the otherwise clean aesthetic. Some users also noted that the widget functionality, while functional, could benefit from more customization options and better visual integration with the main app design. Overall, Habit Diary's design successfully creates an engaging and motivating environment for habit tracking. The interface effectively balances simplicity with functionality, making it accessible to users of all experience levels. We rate design at 8.5 out of 10, acknowledging the app's strong visual foundation while noting areas where the user experience could be further enhanced. 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. | 5.5 Habit Diary offers a freemium model with both free and premium features. The free version provides basic habit tracking functionality but comes with limitations on the number of habits you can track and some advanced features. Premium features include:
In-app purchases range from €7.49 to €28.99, with options for monthly, yearly, or lifetime subscriptions. The free version is ad-supported, which some users find intrusive, but it does provide enough functionality to evaluate whether the app fits your needs before upgrading. However, several factors limit the value for money. Users consistently mention that the free version restricts the number of habits they can track, which can be frustrating for serious users. The free version's ad-supported model creates a fragmented user experience that some users find off-putting. We rate value for money at 5.5 out of 10. While the app provides solid functionality and competitive pricing for premium users, the free version's limitations and ad-supported model create a mixed value proposition that may not appeal to all users.

| 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. | 9.0 Habit Diary excels in user experience, with most users finding the app remarkably easy to navigate and use. The interface design prioritizes simplicity, making it accessible even for users who are new to habit tracking apps. Highlights include:
The only minor quirk is that some advanced features might benefit from more detailed onboarding or help documentation. Once learned, it's easy to use. Overall, Habit Diary's ease of use is one of its greatest strengths. The app successfully balances simplicity with functionality, making habit tracking accessible to a wide range of users. We rate ease of use at 9.0 out of 10, recognizing the app's excellent user experience while noting that some premium features could benefit from enhanced user guidance. 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. | 6.5 Habit Diary's security and privacy practices present a mixed picture that reflects the typical approach of freemium apps in the habit tracking space. While the app doesn't appear to have major security vulnerabilities, there are some privacy considerations that users should be aware of. We found no evidence of third-party analytics or tracking tools. The app only requests essential permissions, such as notifications for reminders. This commitment to privacy is rare and highly appreciated. However, there are some privacy concerns that impact our rating:
While Habit Diary doesn't appear to have any egregious privacy violations, the lack of clear information about data practices and the ad-supported model in the free version create uncertainty about how user information is handled. We rate security and privacy at 6.5 out of 10, acknowledging that while there are no major red flags, users should be aware of the potential data sharing implications of using the free version.

| 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. | Habit Diary is a solid habit tracking app that offers a comprehensive set of features for building and maintaining good habits. While the free version has limitations and includes ads, the premium features provide good value for serious users. The app's strength lies in its user-friendly interface and the 30-day challenge system that helps users form lasting habits. However, the freemium model and ad-supported free version may not appeal to everyone. For users who want unlimited habits without paying, Habitive offers a completely free alternative. Those seeking a more elegant design might prefer HabitKit with its beautiful GitHub-style visualization. However, if you value the structured 30-day challenge approach and don't mind the freemium limitations, Habit Diary remains a solid choice in the competitive habit tracking space. |
