| Features Prod Apps's expert score for the 'Features' aspect of each app. | 8.0 Calm's content library is genuinely impressive and sets the standard for meditation apps. The celebrity-narrated sleep stories are the standout feature—falling asleep to Cillian Murphy's voice, Bob Ross painting descriptions, or Rosé's calming narration provides a unique experience users rave about. These aren't just celebrity gimmicks; they're high-quality productions that genuinely help people fall asleep. Outstanding features include:
The library is genuinely extensive, with enough variety that most users find multiple favorites. The quality is consistently high—professional voice work, good production values, and thoughtful content design. Users frequently mention specific favorites like "Painting with Bob Ross" or programs with Tamara Levitt that they return to regularly. The app uses a subscription model, with most content requiring payment. The free version offers limited access, which is standard for premium apps in this category. Some users wish for more free content to evaluate before subscribing, though the free trial provides opportunity to explore the library. A few long-term subscribers mention content updates could be more frequent, though the existing library is large enough that most users have plenty to explore. For daily users who cycle through content quickly, occasional waits for new stories can be noticeable. We're rating features 8.0 out of 10. The celebrity sleep stories, daily programs, and extensive meditation library provide excellent value, making Calm a feature-rich leader in the meditation app category. Winner in this category | 7.0 Simple Habit's core concept—5-minute meditations for busy people—addresses a genuine need. Expert-led content from Google mindfulness experts and former monks provides quality guidance. The "On-the-Go" feature for quick anxiety relief works well for the target audience. Features that work well:
Some users experience technical issues—meditations not loading, playback stopping mid-session, or content becoming inaccessible. The app was recently rewritten, which removed some features like favorites that users relied on. The free version is quite limited, with most content requiring subscription. The Android version has limited development plans according to developers, who suggest using the web version for the best experience. This means new features and improvements may not come to the Android app. We're rating features 7.0 out of 10. The 5-minute format and expert content work well for many users, but technical inconsistencies and limited free content hold it back. |
| Performance Prod Apps's expert score for the 'Performance' aspect of each app. | 7.5 Calm performs reliably for the vast majority of users across 50+ million downloads and two platforms. The 4.8-star iOS rating and 4.1-star Android rating indicate consistent, stable performance that users depend on nightly. Audio playback is smooth, sleep stories run without interruption, and the app handles background playback well while you sleep. Performance strengths:
The app handles demanding use cases well—playing audio continuously through 7-8 hours of sleep, managing large content libraries, and supporting offline downloads. Users who've used Calm for years mention it working consistently night after night, which demonstrates solid long-term reliability. A small percentage of users report occasional audio stopping during sleep sessions or rare app crashes. These issues seem device or configuration-specific rather than widespread problems, as the majority of users don't mention performance concerns. Some users note the splash screen takes a moment to dismiss, though this is designed as a brief mindfulness moment rather than a technical delay. Load times are generally good, with content starting quickly after selection. The app's size and resource usage are reasonable for the extensive content library it manages. Updates are regular, suggesting active maintenance and performance optimization. For an app with 50M+ downloads used nightly by millions, achieving 4.8 stars on iOS demonstrates exceptional performance reliability. The vast majority of users experience smooth, consistent operation exactly when they need it most—during meditation and sleep. We're rating performance 7.5 out of 10. Calm delivers reliable, stable performance for the overwhelming majority of users, with consistent playback and efficient resource usage. The high ratings across millions of users demonstrate performance excellence at scale. Winner in this category | 6.0 Performance varies significantly between platforms and users. The 4.6 Android and 4.8 iOS ratings indicate many users experience smooth performance. However, recent reviews at 3.35 stars show some users are experiencing problems. Performance strengths:
Performance issues some users experience:
The developer recommendation to use the web version for best performance suggests they're aware Android optimization isn't their current focus. This creates uncertainty about whether reported issues will be addressed. We're rating performance 6.0 out of 10. Works reliably for many users (especially on iOS), but enough Android users experience issues that platform-specific problems are a real concern. |
| Design Prod Apps's expert score for the 'Design' aspect of each app. | 7.5 Calm's design successfully creates a soothing, peaceful atmosphere that supports its meditation and sleep mission. The dark, calming color scheme with deep blues and purples sets the right mood immediately. Visual elements are thoughtfully chosen to promote relaxation rather than stimulation, which is exactly what you want from a meditation app. Design strengths:
The interface generally succeeds at fading into the background, letting the content take center stage. For most users, navigation feels natural—open the app, select your content, and start your meditation or sleep session without friction. Some users mention the splash screen "take a breath" message appears frequently and takes a moment before you can access content. While this fits the app's philosophy, a few long-term subscribers find it repetitive after daily use for years. The search function within categories could be more robust for power users who want to explore the full catalog depth. For subscribers, the experience is streamlined. For free users exploring before committing, distinguishing between free and premium content could be clearer, though this is fairly standard for freemium apps. We're rating design 7.5 out of 10. Calm delivers a beautiful, calming visual experience with thoughtful design that supports meditation and sleep. Minor navigation refinements would elevate it further, but the overall aesthetic excellence justifies the premium positioning. Winner in this category | 7.0 Simple Habit won a 2018 Google Material Design Award, demonstrating strong design fundamentals. The interface follows Material Design guidelines with clean visual presentation. Design elements:
Some users mention the UX could be improved compared to newer competitors. The recent app rewrite removed features like favorites, which affected users who relied on that organization method. Navigation could be more intuitive for finding specific content. The design serves its purpose—getting users into meditation quickly. While not cutting-edge in 2025, it's functional and doesn't get in the way of the primary task. We're rating design 7.0 out of 10. Solid, award-winning foundation that works for most users, though some navigation improvements would enhance the experience. |
| Value for Money Prod Apps's expert score for the 'Value for Money' aspect of each app. | 7.0 At around €70 per year (pricing varies by region), Calm positions itself as a premium meditation app, and for most users, the content library justifies the investment. With 50M+ downloads and 4.8 stars on iOS, millions of people clearly find value worth paying for. Users who've subscribed for years mention the app becoming an essential nightly routine they wouldn't want to give up. The value proposition is strong:
For users getting Calm through employer wellness programs, the value is excellent—high-quality content at no personal cost. Even at full price, long-term subscribers frequently mention the subscription has become essential for their sleep quality and mental health, which makes the cost worthwhile. The subscription model is standard for premium apps—the free version offers limited access to encourage paid subscription. Users can try the app during a free trial period to evaluate whether the content works for them before committing long-term. Cancellation through the Play Store is typically one-click, which most users navigate successfully. Some users report billing confusion during trial periods or difficulty with customer service responses when issues arise. A small number mention pricing discrepancies during promotional periods. Like any subscription service, it's important to track trial end dates and verify charges match promotional pricing if taking advantage of special offers. Compared to competitors, Calm sits at the premium end with Headspace, while Medito offers free content. The celebrity narrations and production quality differentiate Calm's value proposition. We're rating value for money 7.0 out of 10. The extensive, high-quality content library with unique celebrity narrations provides solid value for the subscription price, particularly for users committed to regular meditation and sleep improvement. Those with employer coverage get excellent value, and even full-price subscribers generally find the cost justified by daily use. Winner in this category | 5.5 Value assessment for Simple Habit depends heavily on which platform you use and how well it works for you. The pricing ranges from €5.49 to €134.99 for different subscription periods. The value proposition:
The concerns are real though. The free version is very limited—most content locks behind subscription. Some users report even content not marked premium locks after 1-2 sessions. The developers indicated limited Android development plans, suggesting users try the web version for the best experience. For iOS users experiencing the 4.8-star rated app, the value may justify the subscription. For Android users, especially those experiencing technical issues, paying for an app with limited platform support is harder to justify. Free alternatives like Medito offer good meditation content at zero cost with active development. Headspace provides premium features with ongoing support, though at higher pricing. We're rating value for money 5.5 out of 10. Fair value for iOS users and those experiencing smooth performance, but questionable for Android users facing technical issues with limited development support. |
| Ease of Use Prod Apps's expert score for the 'Ease of Use' aspect of each app. | 7.0 Calm is designed to be intuitive, and for most users, it succeeds. Opening the app and starting a meditation or sleep story takes just a few taps. The main interface presents your options clearly—browse by category, check out daily programs, or jump back to recently played content. Playback controls are simple and work as expected. For subscribers in their daily routine, the experience is smooth. Select your favorite sleep story, set a timer if desired, and drift off. The app remembers your preferences, making it easy to return to content you love. Many users mention using Calm nightly for years, which speaks to how well the basic experience works. Usability strengths:
The free trial process is standard for subscription apps—you provide payment information upfront, explore the content during the trial period, and can cancel before being charged. Most users navigate this successfully, though like any subscription app, you need to remember to cancel if you don't want to continue. Some users report specific issues: occasional login difficulties with Google authentication, confusion about which content is free versus premium for non-subscribers, and rare cases of the app stopping playback during the night. A small number of users mention subscription management confusion, though canceling through the Play Store is typically straightforward with one-click unsubscribe. The splash screen appears when opening the app, which some daily users find repetitive over time. For those who want to jump straight into content, this adds a brief delay, though it's designed to encourage that initial mindful breath. We're rating ease of use 7.0 out of 10. The app is genuinely easy to use for the vast majority of users, with intuitive navigation and simple playback. Minor friction points exist, particularly for free users exploring content boundaries, but don't significantly impact the subscriber experience. Winner in this category | 6.5 Simple Habit aims for simplicity—the name makes that promise clear. For many users, particularly on iOS with its 4.8-star rating, the app delivers on that promise. Opening the app and starting a 5-minute meditation is straightforward. What works well:
However, some Android users experience friction. A subset report meditations not loading, requiring app restarts. Some experience playback stopping mid-session. A few users had login difficulties with password reset issues. The recent app rewrite removed favorites, which affected users who relied on that organization. The distinction between free and premium content isn't always clear—some sessions lock after 1-2 uses even when not marked as premium, creating confusion about what's included. Most users find the app simple to use, but technical issues affect enough people that reliability becomes a concern for Android users specifically. We're rating ease of use 6.5 out of 10. Works smoothly for many users, but technical inconsistencies on Android create friction that shouldn't exist in an app promising simplicity. |
| Security & Privacy Prod Apps's expert score for the 'Security & Privacy' aspect of each app. | 7.0 Calm handles user data responsibly with standard privacy practices appropriate for a wellness app. The company partners with major employers and insurance providers, which requires meeting enterprise-level security and privacy standards. With 50M+ downloads and partnerships with Fortune 500 companies, Calm maintains professional data protection practices. Security and privacy strengths:
The app collects usage data to track your meditation progress, favorite content, and streaks—standard for any app with personalization features. This data helps improve your experience by remembering preferences and providing personalized recommendations. The privacy policy outlines what data is collected and how it's used. Financial transactions are processed through Google Play Store, which provides an additional layer of security and familiar payment infrastructure. The Play Store handles payment information rather than the app storing it directly, following best practices for subscription apps. For users concerned about mental health data privacy, Calm's meditation and sleep content choices represent personal information. The app's enterprise partnerships and scale suggest they take this responsibility seriously, though as with any wellness app, users should review the privacy policy to understand data handling. Some users report billing questions during trial periods, which is common across subscription apps and typically relates to understanding trial terms rather than security issues. Standard subscription management through the Play Store provides familiar cancellation options for most users. The lack of data breach reports across millions of users and years of operation demonstrates solid security practices. For a wellness app trusted by major corporations, maintaining strong security and privacy standards is essential to business partnerships. We're rating security & privacy 7.0 out of 10. Calm maintains professional privacy practices appropriate for a wellness app with enterprise partnerships, handles user data responsibly, and shows no history of security breaches across millions of users. Winner in this category | 6.0 Security and privacy for abandoned apps present unique concerns. While Simple Habit hasn't suffered publicized data breaches, the lack of ongoing security maintenance creates inherent risks. Privacy considerations:
The primary security concern isn't current violations but future vulnerability. Security best practices evolve, new exploit methods emerge, and abandoned apps never receive patches. An app collecting user meditation habits, progress data, and payment information needs ongoing security maintenance. Users also face practical privacy concerns—what happens to their subscription data and stored content when an abandoned app eventually shuts down completely? There's no communication about data retention or eventual service termination. We're rating security and privacy 6.0 out of 10. No current major concerns, but the lack of ongoing security maintenance creates growing risk over time. |
| Conclusion A summary of our findings and final thoughts for each app. | Calm has earned its position as a leading meditation and sleep app with 50M+ downloads, 4.8 stars on iOS, and 4.1 stars on Android. The celebrity-narrated sleep stories are genuinely special—falling asleep to Cillian Murphy, Bob Ross, or Rosé provides a premium experience that justifies the subscription for millions of users. The daily programs, extensive meditation library, and variety of soundscapes create comprehensive value. Long-term subscribers frequently mention Calm becoming essential to their nightly routine, helping with sleep quality and stress management over years of use. The production quality is excellent, the content library is extensive, and the app performs reliably for the vast majority of users. For those whose employers provide Calm subscriptions as a wellness benefit, it's an excellent value proposition. Recent Android reviews show some concerns—the last 100 reviews average 3.04 stars, lower than the overall rating. Some users mention billing confusion during free trials, occasional technical issues, and customer service responsiveness questions. These issues appear to affect a subset of Android users rather than representing the typical experience, but they're worth noting. If you're considering Calm, the free trial lets you explore the content library to see if the sleep stories and meditation programs work for you. The celebrity narrations and production quality differentiate it from competitors. For daily meditation and sleep improvement, Calm delivers substantial value that users rely on over years. Alternative options include Medito for free meditation content with no subscription required, and Headspace for premium content with different stylistic approach. But Calm's unique celebrity content and extensive library make it a strong choice for those committed to meditation and sleep improvement. | Simple Habit offers something valuable—5-minute meditations designed specifically for busy people. The 4.6 and 4.8 star ratings across platforms show this format resonates with many users. For people who genuinely struggle to find meditation time, the quick sessions and expert guidance provide real value. The concerns are legitimate though. Recent performance issues affect some users, and the developers have indicated limited Android development plans, directing users to the web version instead. The subscription model feels less justified when active platform development is limited. Technical problems some users experience—loading failures, playback issues—become more frustrating knowing they may not receive fixes. Our recommendation depends on your situation. If you have iOS and want quick meditations, Simple Habit's 4.8-star rating suggests it works well. For Android users, proceed cautiously—check if the app works smoothly on your device before subscribing, and consider that technical support may be limited. Alternatively, Medito offers free meditation with active development, and Headspace provides premium content with ongoing support (despite its own current issues). These options provide more confidence in long-term viability and improvements. |
