| Features Prod Apps's expert score for the 'Features' aspect of each app. | 7.5 Disciplined covers the basics of habit tracking well without overwhelming you with unnecessary features. It focuses on what matters most - helping you build and maintain good habits. The app keeps things simple, which many users actually prefer. Here's what works well:
But there are some limitations. The free version locks away detailed statistics, which frustrates some users. People also want features like grouping related habits together, adding notes to habits, and better streak tracking. While the core tracking works great, the feature set feels a bit basic compared to some alternatives. That's why we give features a 7.5. It's solid for basic habit tracking but missing some advanced capabilities that power users might want. | 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. Winner in this category |
| Performance Prod Apps's expert score for the 'Performance' aspect of each app. | 7.0 Disciplined's performance is generally solid, but there are concerning reports about lag and stability issues that prevent a higher rating. Performance seems to vary depending on your device and how you use the app. Here's what works well:
But there are performance concerns that impact the rating. Several users report that the latest version became "laggy" on their devices, with one user noting that the app made their phone slow and eventually stopped working. Some mention bugs that prevented them from getting value from the app, especially after paying for premium. These issues appearing in recent reviews suggest ongoing performance challenges that need attention. We give performance a 7.0 - generally good, but the reported lag issues and occasional bugs prevent a higher score. Users with older devices should be particularly cautious. | 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. | 8.5 Disciplined's design is one of its best features. Users consistently praise the clean, intuitive interface. We love how it keeps things simple and focuses on what matters most. Here's what makes the design great:
Some users mention areas for improvement, especially around widget customization. One user wished the widget could be more transparent to better match their home screen. The "less is more" approach works well for a habit tracker, though some users might want more visual feedback or customization options. We give design an 8.5 - excellent for its clean, functional approach, with room for minor aesthetic improvements. | 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. | 7.0 Disciplined's value is mixed - users have different opinions about whether the premium features are worth the cost. The pricing strategy and feature distribution significantly impact the overall value. Here's what's good about the value:
But several factors limit the value rating. Many users are frustrated that basic features like detailed statistics are locked behind the premium paywall. Some feel the free version is too limited, while others mention performance issues and bugs that reduce the perceived value. The fact that some users uninstall due to upgrade prompts suggests the freemium model could be better balanced. We give value for money a 7.0 - fair pricing for what's offered, but the free version limitations and some user-reported issues impact the overall value perception. | 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. | 8.0 Disciplined is really easy to use. Most users find it intuitive and straightforward. We can't think of a simpler habit tracker to get started with. The app's simplicity is its biggest strength when it comes to ease of use. Here's what makes it user-friendly:
But there are some usability issues that prevent a higher rating. Several users find the repeatability settings confusing, especially when setting up habits for quitting bad behaviors. Some also want features like adding notes to habits or grouping related habits together. While the basics are easy to use, some advanced features could use better guidance. That's why we give ease of use an 8.0. It's extremely user-friendly for basic operations, though some advanced features might take a little time to figure out. | 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. | 7.5 Disciplined's approach to security and privacy seems standard for a habit tracking app, though we found limited specific information about their data practices during testing. Here's what we know:
But there are some concerns that prevent a higher rating. The app has privacy policy and terms of service on their website, but we couldn't find details about data encryption, third-party sharing, or specific security measures. The fact that it syncs data across devices raises questions about how secure the data transmission and storage are. We give security and privacy a 7.5 - adequate for basic use, but users concerned about data privacy should check the app's privacy policy for more specific details. | 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. | Disciplined is a solid choice if you want a simple, effective habit tracker. It doesn't try to be everything to everyone - it just does habit tracking really well. The clean design makes it easy to use, and the pricing is fair for what you get. The free version is limited, but the premium upgrade is worth it if you want better analytics and features. This app's strength is that it stays focused on helping you build better habits without overwhelming you with unnecessary complexity. For users who want unlimited free habits, Habitive is the best option. Those seeking elegant design might prefer HabitKit with its beautiful GitHub-style visualization. If you want gamification, Habitica offers unique RPG elements. However, if you prefer simplicity and focus without distractions, Disciplined provides exactly what you need. Quick SummaryBest for: People who want simple, effective habit tracking without distractions Not ideal for: Users who need advanced analytics or social features Value: Good free version, reasonable premium pricing | 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. |
