| Features Prod Apps's expert score for the 'Features' aspect of each app. | 9.0 Merlin AI has everything you'd want in an AI assistant. It brings together seven different AI models - ChatGPT, Grok AI, DeepSeek, Gemini, Claude, and Perplexity AI - all in one place. This means you don't need separate subscriptions for each one. We really liked the 70+ AI tools it comes with:
The best part is how easy it is to switch between different AI models - just one tap and you're using a different AI. Plus, everything syncs across your devices so you can start a conversation on your phone and continue it on your computer. Winner in this category | 8.5 Habitive has all the basic features you'd want in a habit tracker, plus some nice extras. It's not trying to do everything - it focuses on helping you build habits without getting complicated. What we liked most: 1. Unlimited Habits This is where Habitive really shines. Most free habit trackers only let you create 3-5 habits, but Habitive lets you create as many as you want. No artificial limits. Unlike HabitKit which restricts free users to just 4 habits, or Disciplined which locks away detailed statistics behind a paywall, Habitive gives you everything upfront. Setting up a new habit is super simple. Just tap the plus button, pick a name, and choose how often you want to do it each week. That's it. 2. Weekly Goals Instead of forcing you to do something every single day, you can set flexible goals. Want to exercise 4 times a week? No problem. Want to read every day? That works too. This makes it much more realistic for most people's lives. 3. Achievement System The app has a fun game-like system where you unlock achievements as you stick with your habits. It sounds silly, but it actually helps keep you motivated. While not as elaborate as Habitica's full RPG experience, it provides just enough gamification to keep things interesting. 4. Progress Tracking You can see your stats for each habit - how many times you've completed it, your current streak, and a calendar view of your progress. 5. Home Screen Widgets You can add widgets to your phone's home screen so you always see your habits. This is great for staying on track, though some users have reported bugs with this feature. What could be better: The app doesn't let you organize habits into groups or categories. If you have lots of habits, they can feel a bit scattered. Also, syncing between different devices doesn't work very well. For users who need more organizational features, Loop Habit Tracker offers better categorization and grouping options. Overall, we give features an 8.5. It has all the essentials and does them well, but could use some organizational tools. |
| Performance Prod Apps's expert score for the 'Performance' aspect of each app. | 8.0 The app runs smoothly without lag or interruptions when chatting with multiple AI models. The search function works quickly and accurately, so you can easily find your conversations. We tested it on different devices and platforms, and it performed well everywhere. The chat responses are fast, even when switching between different AI models. The cross-device sync works reliably, so you can start a conversation on your phone and pick it up later on your computer. The integration with Gmail and LinkedIn works well without delays. We did notice some occasional loading times when processing complex requests or large documents, but overall the performance is consistent and reliable for everyday use. The best part is that basic features work offline, so you can access your conversations even without an internet connection. | 8.8 The app runs smoothly most of the time. You can track habits without any delays or crashes. Marking habits as complete is fast and reliable. You can also check your progress and stats without waiting. The app works offline, so you can use it anywhere, even without internet. What works well:
There are some issues though. Several users reported problems with home screen widgets - sometimes adding a widget makes the app stop opening. You have to remove the widget to fix it. Some people also said the app doesn't work properly on certain phones. This might be due to specific phone models or software versions. Overall, the main app works great, but the widget feature and device compatibility have some problems. We give performance an 8.8 - generally excellent for daily use, but with some technical issues.

| 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 find what you need without getting lost in menus. The chat interface is well-designed with clear differences between responses from different AI models. We liked how the app works the same way whether you're on Android, iOS, or desktop. It adapts nicely to different screen sizes. The dark and light theme options are a nice touch, and you can customize the interface to your liking. The mobile version works really well too - you can easily access your AI conversations on your phone without any issues. | 9.2 The app looks really good. It's clean, modern, and easy on the eyes. We especially liked how simple everything is - no clutter, just what you need. Users love the dashboard and how easy it is to find things. Everything is organized logically, so you don't waste time looking for features. It also works great on different screen sizes - looks good on both phones and tablets. Design highlights:
People in the reviews keep saying things like "bright and beautiful," "looks great," and "the style is so consistent." Some users mentioned wanting more color options or themes, but honestly, the current design is so good that this feels like a minor request. While HabitKit might have the most elegant GitHub-style visualization, Habitive's design is more approachable and user-friendly. We give design a 9.2. It looks professional and makes you want to use the app every day. Winner in this category |
| Value for Money Prod Apps's expert score for the 'Value for Money' aspect of each app. | 9.0 Merlin AI offers great value. You can use it for free without creating an account, and you get 102 queries per day across all the major AI models. This free access to ChatGPT, Grok AI, DeepSeek, Gemini, Claude, and Perplexity AI in one app saves you from needing multiple expensive subscriptions. The premium plan adds useful features like voice chat, advanced AI tools, and team collaboration. The pricing is reasonable, making it a good choice for students, professionals, and anyone who wants to boost their productivity. When we compared it to individual subscriptions for these AI services, Merlin AI saves you money while offering more convenience. You really can't find another tool that gives you this much value for so little cost. | 10 You can use Habitive completely free without creating an account. You get access to features that other apps charge money for. To get all the benefits - unlimited habits, achievements, widgets, and progress tracking - you don't need to pay anything. It's all included in the free version. The pricing is amazing. It's perfect for students, working professionals, or anyone who wants to build better habits without spending money. No other app gives you this much for free. Why it's such good value:
Users keep saying things like "perfect and free," "nothing's behind a paywall," and "rare to find an app that doesn't force you to buy subscriptions." We give value for money a 10.0. Habitive sets the standard for free apps - you get premium quality without paying anything. While HabitKit offers beautiful design, it requires premium for unlimited habits, and HabitNow has comprehensive features but also uses a freemium model. Winner in this category |
| Ease of Use Prod Apps's expert score for the 'Ease of Use' aspect of each app. | 9.0 Merlin AI is one of the easiest AI assistants we've tried. You can start using it right away without any complicated setup. The free tier gives you 102 queries per day, which is plenty to test everything out. Installing it is simple, and it works great on both Android and iOS. Switching between AI models is super easy - just tap to change from ChatGPT to Grok AI to Claude, and so on. The integration with Gmail and LinkedIn works smoothly. You don't need to configure anything complicated. The free tier lets you explore all the features without committing to anything, which makes it easy to learn at your own pace. We give it a 9 out of 10 because it's really user-friendly, though some of the more advanced features might take a bit of time to figure out. | 9.5 This might be the easiest habit tracker we've ever used. The best part? You don't need an account or any setup - just install and start using it. Installation is simple on both Android and iOS. Once it's on your phone, creating your first habit takes about 10 seconds. The 3-click setup they advertise is real. Name your habit, pick an icon, and set your weekly goal. Done. You don't need any tutorials or help guides. The app is so intuitive that you'll figure everything out just by using it. At first, all the features might seem like a lot, but you'll get the hang of it quickly. The habit management is especially simple compared to other trackers we've tried. What makes it easy:
Reviews keep saying things like "really easy to use," "intuitive," and "does exactly what it says." We give ease of use a 9.5. It's extremely user-friendly, though some of the more advanced features might take a minute to figure out. Winner in this category |
| Security & Privacy Prod Apps's expert score for the 'Security & Privacy' aspect of each app. | 7.0 For security and privacy, we give Merlin AI a 7 out of 10. The app uses standard encryption for your conversations and personal data, which is good. However, since it connects to multiple AI providers, your data might be shared with these third-party services. This is mentioned in their privacy policy, but it's something to be aware of. The app doesn't ask for unnecessary permissions, but remember that your conversations and any documents you upload are processed by external AI services. While the company is transparent about how they use data, we would have liked more control over what gets shared with which AI providers. They do a good job of being upfront about it, but some users might want more control over their data. | 9.0 For security and privacy, we give Habitive a 9.0 out of 10. The fact that you don't need an account is a big plus - it means the app isn't collecting your personal information. Even when you do use the app, it keeps your data private. Your habits, progress, and achievements stay on your phone by default. This means your information is much safer from hackers or data breaches. The app doesn't sell your data to other companies or use it for advertising. Everything stays private and is only used to make the app work. What we liked about privacy:
There is one downside though. Since everything is stored locally, if you lose your phone or it breaks, you'll lose all your habit data. There's no backup in the cloud. For users who prioritize maximum privacy, Loop Habit Tracker offers similar offline-first privacy with additional backup options. We give security and privacy a 9.0. Habitive takes privacy seriously by keeping your data local and not collecting unnecessary information. Winner in this category |
