| 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. | 8.7 To-Do List - Schedule Planner delivers an impressive array of features that go well beyond basic task management. The app truly shines when it comes to flexibility and comprehensive planning tools. Key features that stand out include:
The Wear OS support is a nice touch for smartwatch users, though we didn't test this extensively. Multiple theme options let you customize the look, including a dark mode for nighttime use. However, some limitations prevent a higher score. Many polished features—like additional theme options and advanced scheduling—sit behind the premium paywall. The occasional bug causes recurring tasks to disappear, a frustration multiple users report. Natural language input for quick task entry is missing, as are collaboration features for sharing lists with family or coworkers. Overall: 8.7/10—comprehensive and functional, yet hampered by premium restrictions and occasional bugs. Winner in this category |
| 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. | 8.5 Performance-wise, To-Do List - Schedule Planner generally delivers a smooth and responsive experience, though not without occasional hiccups. The app launches quickly—within 2-3 seconds on our test devices (though the multiple ads on launch add annoying delays). Once running, navigation between screens is snappy. Switching from your task list to calendar view or checking completed items happens instantly. Creating new tasks, editing existing ones, and checking items off all feel immediate with no noticeable lag. Performance highlights:
However, we did encounter some bugs that multiple users also reported. The most concerning is recurring tasks occasionally disappearing or not repeating as configured. This happened to us twice during testing, requiring us to manually recreate the tasks. We also experienced one instance where the app crashed when trying to edit a task with many sub-items, though this wasn't reproducible. The ad-loading mechanism in the free version can cause brief freezes, particularly on slower connections. Some users reported that ads occasionally fail to load properly, leaving the close button non-functional and forcing an app restart. The core functionality performs well, with good speed and reasonable resource usage. The bugs are concerning but not constant, affecting usability occasionally rather than consistently. Overall: 8.5/10—generally reliable and fast, though stability issues need addressing. Winner in this category |
| 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. | 8.2 The design of To-Do List - Schedule Planner is clean and functional, though it doesn't quite reach the aesthetic heights of some premium competitors. The interface follows a straightforward approach that prioritizes usability over visual flair. What works well:
Icons are simple and recognizable, though they lean toward generic rather than distinctive. Where the design falls short is in refinement and consistency. Ad placements in the free version disrupt the visual flow, sometimes appearing multiple times on launch in ways that feel intrusive. Some users noted that the UI can feel a bit dated compared to modern Material Design standards. The premium upsell prompts with countdown timers feel aggressive and detract from the otherwise clean aesthetic. Animations are minimal—tasks check off smoothly, transitions happen quickly. The widget design works fine but won't win beauty contests. Overall: 8.2/10—solid and usable, but lacking the polish and visual appeal that would make it memorable. Winner in this category |
| 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. | 7.8 Value for money with To-Do List - Schedule Planner depends heavily on whether you're comfortable using the ad-supported free version or willing to pay for premium features. The free version provides genuine utility. You can create unlimited tasks, set reminders, use categories, add sub-tasks, view your calendar, and sync via Google Drive—all without paying. For basic task management needs, this covers the essentials. Many users we saw in reviews were satisfied using the app completely free, especially students and casual users who don't mind occasional ads. However, the ads are a significant detractor. Multiple users complained about intrusive ad placement, with some reporting that ads appear multiple times on every app launch and occasionally glitch, requiring app restarts. The aggressive premium upselling with countdown timer prompts also frustrated several users who felt pressured rather than persuaded. These elements diminish the free experience more than necessary. The premium tier removes ads and unlocks additional themes, wallpapers, and potentially other features, though the exact premium feature list isn't entirely clear from the store listing. Pricing ranges from €1.09 to €57.99, suggesting multiple subscription tiers or a lifetime purchase option. Without clear differentiation of what each tier offers, it's hard to assess whether the premium pricing is fair. Compared to alternatives, the value proposition is mixed. Habitive offers unlimited habits and tasks completely free with no ads. Loop Habit Tracker is open-source and feature-complete at no cost. Even HabitKit provides an ad-free experience in its free tier, though it limits you to 4 habits. For users needing comprehensive task management with calendar integration who don't want to pay, the free tier remains serviceable despite the ads. Premium might be worthwhile for daily users bothered by ads, though it's hard to assess whether the €57.99 tier represents good value without trying it. Overall: 7.8/10—decent free functionality undermined by aggressive monetization and unclear premium benefits. Winner in this category |
| 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. | 9.0 Ease of use is where To-Do List - Schedule Planner truly excels. The app's learning curve is remarkably gentle, and we were creating tasks and organizing lists within seconds of first launch. Creating a new task is dead simple: tap the plus button, type your task name, and you're done. Want to add more details? Tap the task to set a reminder, assign it to a category, add priority stars, or break it into sub-tasks. This progressive disclosure approach means beginners aren't overwhelmed, while power users can dive into advanced options when needed. Highlights include:
A few minor friction points exist. The initial setup flow includes aggressive premium prompts that can be confusing for new users trying to access basic features. Some users reported that the tutorial felt unnecessary or difficult to skip. Recurring tasks occasionally behave unexpectedly, requiring users to double-check that repeating items are properly configured. Despite these small issues, the experience remains smooth and intuitive. Most functions work exactly as expected—the hallmark of good usability design. Overall: 9.0/10—excellent accessibility for all skill levels, with only minor stumbling blocks. Winner in this category |
| 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. | 7.5 Privacy and security with To-Do List - Schedule Planner presents a mixed picture. The app requires several permissions that may raise concerns for privacy-conscious users, though most are justifiable given its feature set. The app requests access to your calendar, storage, and audio recording capabilities. Calendar access makes sense for integration with your existing schedule. Storage permissions are needed for local data storage and the cloud sync feature via Google Drive. Audio recording is required if you use any voice input features, though this isn't a core function for most users. Cloud sync through Google Drive is optional, which we appreciate. If you're comfortable with Google's data handling, this provides a convenient backup and cross-device access. However, the app doesn't clearly communicate what data is synced or how it's encrypted during transmission and storage. We couldn't find a detailed privacy policy easily accessible within the app or on the developer's website. The developer, BetterApp Tech Co., Limited, is based in Hong Kong. While this doesn't inherently indicate security concerns, users subject to certain data protection regulations (like GDPR) may want to understand how their data is handled across jurisdictions. The app doesn't require account creation for basic use, which is a privacy plus—your tasks stay on your device by default. We didn't find evidence of data being sold to third parties, though the free version includes ads, which typically involves some level of user tracking for ad targeting. The app hasn't been involved in any known security breaches, which is reassuring. The lack of end-to-end encryption for synced data is notable, especially for users storing sensitive work tasks or personal information. Password protection for the app itself is also absent, meaning anyone with access to your unlocked phone can view your tasks. Overall: 7.5/10—adequate for casual use, but concerning for highly sensitive data or privacy-focused users. Winner in this category |
| 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. | To-Do List - Schedule Planner delivers a solid, feature-rich task management experience that has rightfully earned its place among 10 million users. The app's comprehensive feature set—including calendar views, recurring reminders, sub-tasks, widgets, and cloud sync—covers virtually everything you'd need for personal task management. The recent uptick in ratings to 4.72 stars suggests the developers are responsive to feedback and actively improving the experience. The app's greatest strength lies in its flexibility and depth. Whether you're a student organizing study schedules, a professional managing work projects, or someone trying to keep track of daily routines, the tools are there. The calendar integration provides excellent visualization, the widgets offer convenient quick access, and the categorization system helps keep complex task lists manageable. For users who need comprehensive planning tools in a single app, this delivers. However, we can't ignore the significant drawbacks. The advertising in the free version crosses from acceptable to intrusive, with multiple ads on launch and occasional glitches that force app restarts. The aggressive premium upselling with countdown timers feels pushy rather than persuasive. Most concerning are the recurring bugs where tasks disappear or don't repeat properly—reliability issues that undermine trust in a productivity tool. Privacy-conscious users will also find the permission requirements and unclear data practices concerning. The value proposition depends on your tolerance for ads and willingness to pay. The free version is genuinely usable for basic needs, but the experience is compromised enough that many users will feel pressured toward premium. For those seeking completely free alternatives without these compromises, Habitive offers unlimited features with no ads, while Loop Habit Tracker provides excellent open-source functionality. If you prioritize design and are willing to pay, HabitKit offers superior aesthetics with transparent pricing. We recommend To-Do List - Schedule Planner if you specifically need comprehensive task management with calendar integration and are either willing to tolerate ads or pay for premium. It's a capable tool that does the job well when it works. However, if you're looking for a more polished, reliable, or privacy-focused experience, the alternatives mentioned above may serve you better. The app earns a solid 8.3/10 overall—good enough to be useful, but with room for meaningful improvements in user experience and reliability. |
