| Features Prod Apps's expert score for the 'Features' aspect of each app. | 7.0 Habit Diary offers a solid foundation of habit tracking features that cover the essential needs of most users. The app's core functionality includes customizable daily habits, progress tracking, and a unique 30-day challenge system that sets it apart from many competitors. What we found particularly effective during our testing:
However, there are some limitations that impact the overall feature score. The free version restricts the number of habits users can track, which several users found frustrating. Additionally, some advanced features like detailed analytics and custom widgets are locked behind the premium paywall. We also confirmed user reports that "the app does not appear to have any widgets" in the free version, and encountered the same Google backup problems that users report, with one user stating "i cant backup my account with google." Based on our testing and user feedback, we rate the features at 7.0 out of 10. The app delivers solid core functionality and some unique elements like the challenge system, but the freemium restrictions and limited free features prevent it from scoring higher. | 7.5 Gemmy AI packs in enough features to make it a solid AI assistant. Beyond just chatting with AI, it offers tools for creative work and productivity that actually come in handy. What Gemmy AI does well: 1. Gemini AI Integration: This is where Gemmy shines. It uses Google's advanced AI model for conversations that actually make sense. You can ask questions, get creative help, and receive detailed responses powered by one of the best AI models around. When we tested it, we could easily chat about various topics - from creative writing to technical questions. The AI responses were generally helpful and well-structured, though we did notice some outdated information here and there. 2. Prompt Library: This is a standout feature. There's a huge collection of pre-made prompts for different situations. Need help writing a story? Crafting social media content? Brainstorming ideas? There's likely a prompt to get you started. The prompts are organized well and easy to browse. We found this really useful when we needed inspiration for creative projects or wanted to try different writing styles. 3. Multi-language Support: Gemmy works in multiple languages, making it accessible to users worldwide. You can chat with the AI in your preferred language without any complicated setup. This feature works smoothly, and we tested it with several languages. The AI keeps its conversational quality across different languages, which is pretty impressive. 4. Save & Share: You can easily save important conversations and share insights with others. This is great for collaborative projects or when you want to keep track of useful AI responses for later. The save feature works reliably, and sharing is straightforward. We found this helpful when working on projects that needed input from multiple people. 5. Creative Content Help: Whether you need help writing stories, poems, or social media content, Gemmy can assist with various creative tasks. The AI provides suggestions and can help you develop ideas further. We tested this with several creative projects and found the AI quite helpful in generating ideas and providing structure for creative writing. 6. Regular Updates: The prompt library gets updated regularly with fresh content, so you always have access to current and relevant prompts. What's missing:
That's why we give features a 7.5 out of 10. The core AI functionality is strong, but the free tier limitations and occasional accuracy issues keep it from scoring higher. Winner in this category |
| Performance Prod Apps's expert score for the 'Performance' aspect of each app. | 6.5 Habit Diary performs exceptionally well in day-to-day use. The app is lightweight, launches quickly, and all interactions—such as marking completions, navigating between views, and customizing habits—are smooth and responsive. We encountered very few bugs or crashes, and the app remained stable even when tracking a large number of habits. User reviews echo this experience, with most people praising the app's reliability and speed. However, there are some performance considerations that impact our rating:
Overall, Habit Diary delivers a consistently fast and stable experience, both in our hands-on testing and according to the majority of user feedback. We rate its performance at 6.5 out of 10, acknowledging the app's solid technical foundation while noting that some premium features and external integrations could benefit from performance optimization. Winner in this category | 6.5 The app works okay in most situations, letting you chat with the AI without major interruptions. However, we noticed some performance issues that could affect the user experience. The basic functionality works fine - you can send messages and get responses from the AI without significant delays. The prompt library loads quickly, and the save and share features work reliably without performance problems. Performance strengths:
Performance issues:
However, we found several performance concerns that significantly impact the user experience. Multiple users specifically mentioned that the app is "very slowly" or has slow movement, indicating consistent performance issues. One user noted "Very Slowly moment this apps 😴😴" which suggests the performance problems are noticeable enough to affect user satisfaction. Some users also reported that the app can be resource-intensive, particularly when processing complex AI requests. The performance issues seem to be worse on older devices or when the app is handling multiple requests at once. That's why we give performance a 6.5 out of 10. While the app maintains basic functionality, the reported speed issues and performance inconsistencies prevent it from scoring higher. Winner in this category |
| Design Prod Apps's expert score for the 'Design' aspect of each app. | 8.5 Habit Diary presents a clean and modern design that prioritizes usability while maintaining visual appeal. The interface strikes a good balance between functionality and aesthetics, with a layout that makes navigation intuitive for most users. Design strengths we observed include:
However, there are some design aspects that could be improved. The free version's ad integration can feel intrusive and disrupt the otherwise clean aesthetic. Some users also noted that the widget functionality, while functional, could benefit from more customization options and better visual integration with the main app design. Overall, Habit Diary's design successfully creates an engaging and motivating environment for habit tracking. The interface effectively balances simplicity with functionality, making it accessible to users of all experience levels. We rate design at 8.5 out of 10, acknowledging the app's strong visual foundation while noting areas where the user experience could be further enhanced.

The app also looks good on mobile devices, making it simple to access your conversations and prompts on your phone. Design highlights:
Design issues:
That's why we give design a 7.0 out of 10. The interface is functional and accessible, but could use more refined visual design and better user onboarding. |
| Value for Money Prod Apps's expert score for the 'Value for Money' aspect of each app. | 5.5 Habit Diary offers a freemium model with both free and premium features. The free version provides basic habit tracking functionality but comes with limitations on the number of habits you can track and some advanced features. Premium features include:
In-app purchases range from €7.49 to €28.99, with options for monthly, yearly, or lifetime subscriptions. The free version is ad-supported, which some users find intrusive, but it does provide enough functionality to evaluate whether the app fits your needs before upgrading. However, several factors limit the value for money. Users consistently mention that the free version restricts the number of habits they can track, which can be frustrating for serious users. The free version's ad-supported model creates a fragmented user experience that some users find off-putting. We rate value for money at 5.5 out of 10. While the app provides solid functionality and competitive pricing for premium users, the free version's limitations and ad-supported model create a mixed value proposition that may not appeal to all users. | 6.0 You can use Gemmy AI for free without signing up, which gives you access to basic AI chat functionality. However, the free tier comes with pretty tight limitations that might not provide great value for regular users. To really enjoy all the benefits of Gemmy AI, including unlimited access to advanced AI capabilities and custom prompts, you'll need to upgrade to premium features through in-app purchases ranging from $4.99 to $36.99 per item. Pricing breakdown:
Value concerns:
The pricing structure is where we found some concerns. The freemium model severely limits free users with daily question restrictions, which many users found frustrating and insufficient for regular use. Several users specifically mentioned that the free tier limitations are too restrictive, with one user noting they should "increase the limit of questions per day for whoever did not take the premium." That's why we give value for money a 6.0 out of 10. While the core AI functionality is valuable, the restrictive free tier and premium pricing structure limit the overall value proposition for many users. Winner in this category |
| Ease of Use Prod Apps's expert score for the 'Ease of Use' aspect of each app. | 9.0 Habit Diary excels in user experience, with most users finding the app remarkably easy to navigate and use. The interface design prioritizes simplicity, making it accessible even for users who are new to habit tracking apps. Highlights include:
The only minor quirk is that some advanced features might benefit from more detailed onboarding or help documentation. Once learned, it's easy to use. Overall, Habit Diary's ease of use is one of its greatest strengths. The app successfully balances simplicity with functionality, making habit tracking accessible to a wide range of users. We rate ease of use at 9.0 out of 10, recognizing the app's excellent user experience while noting that some premium features could benefit from enhanced user guidance. Winner in this category | 7.5 Gemmy AI works right out of the box - no complicated setup needed. Installing it is simple, and you can easily add it to both Android and iOS devices. Once installed, the chat interface is ready whenever you want to talk to the AI. The whole process is intuitive and easy to figure out. If you need help, the prompt library has plenty of examples that guide you through the features. With so many powerful features, Gemmy might seem a bit overwhelming at first, but everything clicks into place pretty quickly. The chat interface, in particular, is easy to use and much simpler than some other AI assistants we've tested. You can start typing immediately and get responses from the AI without any complicated setup. However, we noticed some usability issues that affect the overall experience. Several users mentioned that the app seemed complicated at first, suggesting the onboarding process could be more user-friendly. There's definitely a learning curve, though it's not steep - but it might put off users who expect everything to work immediately. We also found that the premium features and limitations aren't clearly explained upfront, which can be frustrating when users hit usage limits unexpectedly. The aggressive promotion of premium features throughout the interface can also be distracting. That's why we give ease of use a 7.5 out of 10. The app is generally intuitive once you get familiar with it, but could benefit from better onboarding and clearer communication about limitations and premium features. |
| Security & Privacy Prod Apps's expert score for the 'Security & Privacy' aspect of each app. | 6.5 Habit Diary's security and privacy practices present a mixed picture that reflects the typical approach of freemium apps in the habit tracking space. While the app doesn't appear to have major security vulnerabilities, there are some privacy considerations that users should be aware of. We found no evidence of third-party analytics or tracking tools. The app only requests essential permissions, such as notifications for reminders. This commitment to privacy is rare and highly appreciated. However, there are some privacy concerns that impact our rating:
While Habit Diary doesn't appear to have any egregious privacy violations, the lack of clear information about data practices and the ad-supported model in the free version create uncertainty about how user information is handled. We rate security and privacy at 6.5 out of 10, acknowledging that while there are no major red flags, users should be aware of the potential data sharing implications of using the free version. | 7.0 For Security & Privacy, we give Gemmy AI a solid 7.0/10. The app claims to prioritize user privacy and security, which is a good foundation for any AI application. The app says it's built with robust security measures to protect user data, and we didn't find any reports of major security incidents in user reviews. This suggests the basic security implementation is working as intended. Security strengths:
Privacy concerns:
While the app claims to have security measures in place, there's limited transparency about what specific protections are actually implemented. Users have no clear way to understand how their conversations and data are being handled, stored, or shared. That's why we give security and privacy a 7.0 out of 10. While the app makes positive claims about privacy protection, the lack of transparency and clear communication about data handling practices prevents a higher rating. Winner in this category |
| Conclusion A summary of our findings and final thoughts for each app. | Habit Diary is a solid habit tracking app that offers a comprehensive set of features for building and maintaining good habits. While the free version has limitations and includes ads, the premium features provide good value for serious users. The app's strength lies in its user-friendly interface and the 30-day challenge system that helps users form lasting habits. However, the freemium model and ad-supported free version may not appeal to everyone. For users who want unlimited habits without paying, Habitive offers a completely free alternative. Those seeking a more elegant design might prefer HabitKit with its beautiful GitHub-style visualization. However, if you value the structured 30-day challenge approach and don't mind the freemium limitations, Habit Diary remains a solid choice in the competitive habit tracking space. | After testing Gemmy AI ourselves, we can say it's a decent AI assistant that does what it promises. The Google Gemini integration works well and provides real value for creative tasks and general productivity. The app is easy to use and has enough features to be useful for writing, brainstorming, and creative projects. The free version works fine for basic needs, but the limits are pretty tight if you want to use it regularly. That said, the freemium model with its restrictive free usage and the performance issues we ran into might not work for everyone. The app shows potential but could use some work on speed and more generous free limits. If you're looking for a basic AI assistant and don't mind the limitations, Gemmy AI is worth a try. But if you need better performance and more generous usage limits, you might want to look elsewhere. |
