| Features Prod Apps's expert score for the 'Features' aspect of each app. | 9.0 Microsoft Copilot has a lot of useful features. The main thing it does really well is chat with you like a helpful friend. You can ask it questions, get help with writing, or just have a conversation. You don't even need to sign up to start using it. What we really liked:
Winner in this category | 7.5 Thunder VPN delivers a solid foundation of core VPN features that meet the basic needs of most users. The app's feature set is straightforward and focused on simplicity rather than advanced functionality, which aligns well with its target audience of casual VPN users. Key features we found most valuable include:
However, Thunder VPN lacks many advanced features that users expect from premium VPN services. There's no kill switch to protect against connection drops, no split tunneling to route specific apps through the VPN, and no specialized servers for streaming or torrenting. The server selection is limited compared to premium alternatives. While the core features work well for basic privacy and geo-unblocking needs, power users will find the feature set limiting. For users who need advanced features like kill switches, split tunneling, or specialized servers, alternatives like Proton VPN offer more comprehensive free tiers, while NordVPN provides extensive advanced features for premium users. We rate features at 7.5 out of 10—good for basic VPN needs with better user experience than most free alternatives, but lacking the depth that serious users require. |
| Performance Prod Apps's expert score for the 'Performance' aspect of each app. | 9.0 Microsoft Copilot works really well. The chat responses come back quickly, and the AI usually understands what you're asking for. We didn't experience any lag or crashes while using it. The image creation feature is surprisingly fast. You describe what you want, and within a few seconds, you get a picture. The quality is usually pretty good too. The voice feature works smoothly. It understands what you're saying most of the time, and the responses are clear and natural-sounding. If you use it with Microsoft Office apps, the integration works seamlessly. You can switch between Copilot and your documents without any problems. The app doesn't drain your battery too much, and it doesn't take up a lot of storage space. Overall, it performs really well for an AI assistant. Winner in this category | 6.5 Thunder VPN's performance presents a mixed picture that reflects the challenges of maintaining a free VPN service. While the app can deliver fast connections when working properly, reliability issues significantly impact the overall performance experience. Performance strengths include:
However, significant performance issues undermine the user experience:
User reviews reveal a pattern of performance issues, with many users praising the app's speed when it works but complaining about frequent disconnections. The app's focus on user experience over aggressive monetization may be impacting server quality and maintenance. For users seeking reliable performance, alternatives like Proton VPN offer more consistent free performance with better server maintenance, while NordVPN provides premium performance with dedicated servers and better reliability guarantees. We rate performance at 6.5 out of 10—good speeds when working but undermined by frequent connection drops and stability issues that create an inconsistent user experience. |
| Design Prod Apps's expert score for the 'Design' aspect of each app. | 8.0 The app looks clean and modern. It's easy to figure out how to use it, even if you've never used an AI assistant before. The chat interface is simple - just type and hit send, like texting a friend. We liked how the image creation feature works. You just type what you want to see, and the app shows you the picture. It's straightforward and doesn't require any special knowledge. The voice feature has nice visual feedback - you can see when it's listening and when it's processing what you said. This makes it feel more natural to use. Overall, the design is good but not perfect. Some parts could use a bit more polish, but it gets the job done without being confusing. Winner in this category | 8.0 Thunder VPN's design philosophy centers on simplicity and user experience, which works exceptionally well for its target audience. The interface is clean, intuitive, and focuses on functionality rather than flashy design elements. Design strengths we observed include:
The design experience is significantly better than competitors like Turbo VPN and Now VPN, with much less advertising interruption. Users consistently praise the app's clean interface and ease of use, making it one of the most user-friendly free VPNs available. While the core interface design is solid, some users report that the app requires keeping the window open to maintain connections, which can be inconvenient. However, this is a minor issue compared to the overall design quality. For users who value a clean, uninterrupted interface, Thunder VPN offers one of the best free experiences available. Alternatives like Proton VPN offer similar design quality with better privacy protection, while Windscribe VPN provides a comparable free experience with fewer restrictions. We rate design at 8.0 out of 10—excellent design principles with minimal advertising that creates a genuinely user-friendly experience. Winner in this category |
| Value for Money Prod Apps's expert score for the 'Value for Money' aspect of each app. | 8.0 Microsoft Copilot offers good value. You can use it for free, which gives you access to chat with AI and create images. This is actually pretty generous compared to some other AI apps. The free version is good enough for most people. You can ask questions, get help with writing, and create images without paying anything. If you want more features, there's Copilot Pro for $20 per month. This gives you:
It's worth it if you use Office a lot for work. The pricing is reasonable compared to other AI assistants. The free tier is quite good, and the Pro version offers real value for people who need the extra features. Winner in this category | 8.0 Thunder VPN's value proposition is significantly better than most free VPNs, offering a genuinely useful free service with minimal advertising and good performance. The app provides excellent value for users who can tolerate occasional connection issues. Value strengths include:
The free tier's value is significantly better than most free VPNs, with minimal advertising and good performance. However, some limitations affect the overall value:
The premium pricing is reasonable ($1.99-$59.99), but the connection stability issues may not justify the upgrade for many users. Premium VPN services like NordVPN and Surfshark VPN offer more comprehensive features and better reliability for similar or lower costs. For users seeking genuine value, Thunder VPN offers one of the best free experiences available. Alternatives like Proton VPN offer a more generous free tier with better privacy protection, while Windscribe VPN provides a more reliable free experience with fewer restrictions. We rate value for money at 8.0 out of 10—excellent value for a free VPN with minimal advertising and good performance, though connection stability issues limit the overall experience.

| Ease of Use Prod Apps's expert score for the 'Ease of Use' aspect of each app. | 9.0 This is probably one of the easiest AI assistants to use. You can start chatting right away without any complicated setup. No account needed for basic features, which is nice. Getting started is simple:
We didn't need to read any instructions to figure out how to use it. The voice feature is really well done. You just tap the microphone button and start talking. It understands what you're saying most of the time, and the responses are clear. Creating images is also super easy. You just describe what you want, and the AI makes it for you. No need to learn complicated settings or options. We give it a 9 out of 10 because it's so easy to use. Even people who aren't tech-savvy should be able to figure it out quickly. Winner in this category | 7.0 Thunder VPN excels in basic usability with its one-tap connection approach, making it one of the most accessible VPN apps for beginners. The core functionality is genuinely simple and requires no technical knowledge to operate effectively. Usability strengths include:
However, the ease of use is somewhat undermined by connection stability issues. Users report that the app requires keeping the window open to maintain connections, which can be inconvenient. Additionally, frequent connection drops require reconnection, which interrupts the user experience. While the core interface is genuinely easy to use, the connection stability issues compromise the overall user experience. For users seeking a truly hassle-free VPN experience, alternatives like Proton VPN offer a cleaner free tier with better connection stability, while Windscribe VPN provides a more reliable free experience. We rate ease of use at 7.0 out of 10—excellent core usability with good interface design, but undermined by connection stability issues that require user intervention. |
| Security & Privacy Prod Apps's expert score for the 'Security & Privacy' aspect of each app. | 8.0 Microsoft Copilot gets an 8 out of 10 for security and privacy. Since it's made by Microsoft, it uses the same security measures that protect their other products like Office and Windows. Your conversations and the images you create are encrypted, which means they're protected from hackers. Microsoft has a good track record with keeping user data safe. If you sign in with your Microsoft account, you get extra security features like two-factor authentication. This adds another layer of protection to your account. Microsoft is pretty clear about how they handle your data. They don't sell your information to other companies, and you can control what data they collect. Just remember - like with any AI app, don't share really personal or sensitive information. While Microsoft keeps things secure, it's always better to be careful about what you share. Winner in this category | 6.0 Thunder VPN's security and privacy practices present a mixed picture that raises some concerns for privacy-conscious users. While the app claims to offer secure connections and privacy protection, several factors undermine confidence in its privacy commitments. Security strengths include:
However, some privacy concerns emerge from user feedback and business practices:
User reviews reveal mixed experiences, with some users praising the app's privacy features while others express concerns about data collection. The lack of transparency about the service's data handling practices further undermines trust. For users who prioritize privacy and security, alternatives like Proton VPN offer Swiss-based privacy protection with independent audits and transparency reports, while Windscribe VPN provides Canadian privacy protection with more transparent data handling practices. We rate security and privacy at 6.0 out of 10—basic security features present but concerns about data handling, jurisdiction, and transparency that compromise trust in the service. |
| Conclusion A summary of our findings and final thoughts for each app. | We've been using Microsoft Copilot for a while now and really like it.

The free version is pretty good, but if you use Microsoft Office a lot, the Pro version is worth considering. | Thunder VPN represents one of the better free VPN options available, offering a genuinely useful service with minimal advertising and good performance.

However, the frequent connection drops and stability issues suggest that the free model may be impacting server quality and maintenance. For users who can tolerate occasional connection issues, Thunder VPN provides a functional free VPN with minimal advertising.
