| 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. | 9.0 OpenVPN Connect offers an exceptional set of enterprise-grade features that justify its reputation as the gold standard for VPN clients. The app includes AES-256 encryption, TLS 1.3 support, split-tunneling, kill switch, and auto-reconnect capabilities. The service also includes advanced features like device posture checks and SAML SSO support, making it more than just a basic VPN client. What sets OpenVPN Connect apart is its open-source nature and enterprise focus. The app also includes advanced features like IPv6 and DNS leak protection, HTTP proxy configuration, and support for multiple authentication methods including certificates and MFA. However, the service lacks some consumer-friendly features found in all-in-one VPN services, such as built-in server access and simplified setup. The service also doesn't offer some advanced features like specialized streaming servers or geo-blocking bypass that some consumer VPNs provide. Compared to other VPN solutions like Proton VPN or NordVPN, OpenVPN Connect offers superior features for enterprise use, but the lack of built-in service makes it less suitable for casual users. The service provides excellent value for users who need enterprise-grade VPN functionality. 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. | 8.5 OpenVPN Connect's performance is excellent when properly configured, with fast connection speeds and reliable operation. The service offers excellent connection stability and performance, with users reporting consistent speeds and minimal disconnections when using compatible servers. The service works well for enterprise VPN protection, with users reporting reliable connections and good performance. The connection stability is excellent, and the service handles various network conditions well. The service's performance is particularly strong for enterprise use cases, with users reporting excellent reliability and speed. The open-source nature and enterprise focus ensure optimal performance for professional use. Compared to other VPN solutions like Proton VPN or NordVPN, OpenVPN Connect's performance is excellent when properly configured. The service provides reliable performance for users who need enterprise-grade VPN functionality. 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 OpenVPN Connect's interface strikes a good balance between functionality and enterprise usability. The main screen provides quick access to connection profiles, server settings, and security options. The interface is clean and professional, with good attention to detail and user experience for enterprise users. The app's design is functional and well-organized, with clear navigation between different features. The connection status is clearly displayed, and the settings menu is comprehensive. The interface provides good visual feedback about connection status and security features. The interface is generally user-friendly for technical users and provides good visual feedback about connection status and security features. The design reflects the enterprise positioning of the service, making it suitable for professional use. Compared to other VPN clients like Proton VPN or NordVPN, OpenVPN Connect's design is functional but not as polished for consumer use. The interface is professional and functional, with good attention to detail for enterprise users. 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. | 8.5 OpenVPN Connect's value proposition is excellent for enterprise users, with free access to enterprise-grade features and complete transparency. The service offers exceptional value compared to other enterprise VPN solutions, with the ability to get enterprise-grade security for free being a significant advantage. The service's pricing is exceptional for enterprise use, and the open-source nature makes it particularly attractive for organizations that want complete control and transparency. The comprehensive features and security protection add value beyond basic VPN functionality. However, the service's value is impacted by the requirement for technical setup and server infrastructure. Many users need to invest in server hosting or compatible services. The technical requirements make it less suitable for casual users who just want a simple VPN solution. Compared to other VPN solutions like Proton VPN or NordVPN, OpenVPN Connect offers exceptional value for enterprise users but requires significant technical investment. The service provides excellent value for users who need enterprise-grade VPN functionality. 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. Winner in this category | 6.0 OpenVPN Connect is moderately easy to use for technical users, but requires significant setup knowledge for basic functionality. The app's design is functional, but most users need technical knowledge to configure servers and import profiles. The service works well for enterprise users who understand VPN protocols. The service offers profile import and URL-based setup, making it accessible to users with technical knowledge. The app doesn't require complex configuration for basic use, and the VPN connection process is straightforward once configured. The service works well for most enterprise use cases and provides good performance when properly set up. However, the service's ease of use is compromised by the requirement for technical setup and server configuration. Many users report difficulty with initial setup and the need for technical knowledge. The app can be complex to configure, and some users experience issues with profile imports and server compatibility. Compared to other VPN solutions like Proton VPN or NordVPN, OpenVPN Connect's ease of use is significantly more complex. The technical requirements make it unsuitable for casual users who just want a simple VPN solution. 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. | 10 OpenVPN Connect takes security and privacy to the highest level, with enterprise-grade encryption and open-source transparency. The service includes AES-256 encryption, TLS 1.3 support, and advanced features like kill switch and DNS leak protection. The service also includes advanced features like device posture checks for enhanced security. The service's privacy features are exceptional, with complete open-source transparency and no data collection. The service also includes advanced features like IPv6 protection and split-tunneling for enhanced security and privacy protection. OpenVPN Connect has an impeccable security record, with regular security audits and community oversight. The open-source nature ensures complete transparency, and the enterprise focus means the highest security standards are maintained. Compared to other VPN solutions like Proton VPN or NordVPN, OpenVPN Connect's security practices are unmatched. The service provides the highest level of protection for users who prioritize security and transparency. Winner in this category |
| 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. | OpenVPN Connect is the gold standard for enterprise VPN clients, offering unmatched security, transparency, and control. The app's open-source nature and enterprise-grade features make it the top choice for users who prioritize security and are willing to invest in the technical setup required.
For users who need the highest level of VPN security and transparency, OpenVPN Connect is unmatched. However, those seeking a simple consumer VPN solution might find it overly complex compared to all-in-one services that handle both client and server components, such as Proton VPN or NordVPN.
Ultimately, OpenVPN Connect's enterprise focus and open-source transparency make it the best choice for security-conscious users and organizations, but the technical requirements and lack of built-in service make it unsuitable for casual users who just want a simple VPN solution. For a more user-friendly approach with built-in servers, consider ExpressVPN or Surfshark VPN. |
