| 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 | 8.5 Serenity delivers a well-rounded meditation experience without overwhelming complexity. The feature set focuses on what matters for building a consistent practice, and executes this effectively. Standout features:
There are limitations. While the free version generously offers over 2 hours of content, it restricts access to advanced programs. Some users wanted more variety in the free tier, though most agreed the basics provided solid value. The app lacks organizational features found in complex apps—no folders or advanced filtering. This simplicity is intentional and generally works in its favor. Features earn 8.5 out of 10. Core meditation functionality is excellent, the beginner course stands out, and sleep content delivers genuine value. It doesn't match the content volume of Calm or the completely free library of Medito, but what's present is thoughtfully implemented and effective. |
| 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 | 9.0 Serenity performs reliably. Across thousands of recent reviews, technical issues are rarely mentioned—stark contrast to apps like Headspace where performance problems dominate feedback. Performance strengths:
Long-term reliability is impressive. Users with 3+ years of consistent use continue praising the app. One mentioned using it twice daily for years without issues. Another: "3 years later and I'm still using this app. Truly saved my life." The app handles offline mode well. Progress tracking and stats work reliably. Reminders arrive as scheduled. Basic functions work consistently—which should be standard but, as competitor reviews show, often isn't. The only minor performance consideration? Ads in the free version, though users say they're "seamlessly integrated" and not disruptive. No mentions of ad-related lag or crashes. Performance earns 9.0 out of 10. Serenity simply works, consistently, for years. In a market where major apps struggle with crashes and slowdowns, this reliability is a competitive advantage. The app delivers without technical friction. Winner in this category |
| 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. | 9.0 Serenity's design philosophy is refreshingly simple—clean interface, clear navigation, zero clutter. After testing meditation apps that try to do too much visually, this straightforward approach felt intentional and calming. Design strengths:
The design doesn't try to impress with visual flair, and that's its strength. Where Headspace has become cluttered with features and constant UI changes that frustrate users, Serenity maintains consistency. It looks professional without feeling corporate or sterile. Several reviewers compared Serenity's interface favorably to Calm and Headspace. The simpler design made it easier to use, and the lack of visual complexity helps maintain focus on practice rather than navigation. Design earns 9.0 out of 10. The minimalist approach works exceptionally well. It won't win design awards for innovation, but it excels at creating a calm, distraction-free environment that supports meditation.

| 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. | 8.5 Serenity offers strong value, especially compared to subscription-only meditation apps. The pricing model provides genuine flexibility that respects different budgets. The free tier is legitimately useful:
Paid options are flexible:
Multiple users compared Serenity favorably to Calm. One review stated: "I like Calm but this app is a much better deal if you are low on money. The meditation quality is great." Another: "This app is by far the best deal for a simple meditation app." The main value limitation? Medito offers completely free, ad-free meditation with no purchases required. If budget is your primary concern, Medito's perfect 10.0 value rating can't be beaten. However, Serenity's flexible pricing—pay only for what you want—beats subscription-only alternatives. Value for money earns 8.5 out of 10. Free content is genuinely useful, purchasing options are flexible and fairly priced, and quality justifies the cost. While not free like Medito, Serenity delivers considerably better value than premium subscription apps. Winner in this category |
| 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. | 9.5 Serenity is remarkably easy to use. This came up repeatedly in reviews and matched our experience—the app just works, immediately, without friction. What makes it so accessible:
Ease of use particularly shines for beginners. Multiple first-time meditators mentioned Serenity helped them establish regular practice when other apps felt overwhelming. One user switching from another "popular meditation app" (likely Headspace) specifically cited Serenity's simpler layout as crucial during anxiety attacks—they could find what they needed quickly without confusion. Even purchasing is straightforward if you choose to upgrade. Buy specific content packs rather than committing to a full subscription. Flexibility and control. Ease of use earns 9.5 out of 10. This is one of the app's greatest strengths. Serenity removes barriers between you and meditation, making it genuinely effortless to build a practice. The 0.5 deduction? Perfection doesn't exist—but this comes close to frictionless usability. Winner in this category |
| 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. | 9.5 Serenity takes a privacy-friendly approach that stands out. The biggest advantage is simple: no account required means no personal data collection for basic use. Privacy strengths:
Ads in the free version are the main privacy consideration. Users say they're "seamlessly integrated," and they appear to be standard in-app advertising rather than highly targeted data collection. Still, ads typically involve some tracking—worth noting if you're privacy-conscious. For maximum privacy, Medito sets the gold standard with open-source, ad-free, account-free approach. Serenity's practices are solid though—better than subscription apps requiring accounts and more transparent than many competitors. Security and privacy earn 9.5 out of 10. The no-account approach provides excellent privacy. Ads in the free version are the only minor concern, and even that appears handled reasonably. For most users, Serenity's privacy practices are more than adequate. Winner in this category |
| 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. It's great for chatting with AI, creating images, and getting help with work. The free version is pretty good, but if you use Microsoft Office a lot, the Pro version is worth considering. | Serenity delivers what a meditation app should: effective guidance, reliable performance, and genuine accessibility. The 4.8-star rating with 54.2K reviews isn't inflated—the app works well, the narrator's voice is soothing, and the interface stays out of your way. The rising recent rating (4.95 stars) shows quality improving, not declining. What makes Serenity valuable is a rare combination of factors. The free 7-day beginner course provides real value without requiring an account or payment info. Sleep meditations work effectively for long-term users. Flexible pricing respects your budget—buy what you want instead of committing to a subscription. The app maintains this quality over years without the technical deterioration affecting competitors. It's not perfect. Free content is limited beyond basics, ads are present, and the values-focused approach in some sessions won't appeal to everyone. Want completely free meditation? Medito is your choice. Want celebrity narrators and massive libraries? Calm has that (at subscription cost). Need therapy integration? Headspace provides it (though with current technical issues). For straightforward, effective meditation with excellent beginner support and reasonable pricing, Serenity hits the sweet spot. The simplicity is intentional. The focus on fundamentals over feature bloat helps. The consistent praise for ease of use, voice quality, and sleep effectiveness across thousands of reviews isn't marketing—it's genuine experience. We recommend Serenity for beginners building their first meditation practice, anyone struggling with sleep who wants guided sessions, and users who appreciate simplicity. The free content lets you test it without commitment. If it clicks, flexible purchasing provides fair value. Reliable performance won't get in the way of developing consistent practice. |
