| 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 | 8.2 Habitica is honestly unlike any other habit tracker we've used. It turns your daily tasks into a full-on RPG adventure, which makes building routines way more fun. You can track habits, daily routines, and one-off to-dos, and you get experience, gold, and collectibles for checking things off. It's surprisingly motivating!
We did wish there were more advanced stats and better ways to manage tasks (like duplicating or redoing them). We also ran into a few bugs that messed with streaks or notifications. Still, Habitica's features are fun and keep you coming back—especially if you like games. We give features an 8.2 out of 10. |
| 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. Winner in this category | 7.2 Most of the time, Habitica runs smoothly and does what you need. We did run into some slowdowns, bugs, and issues with notifications or widgets—something other users have mentioned too. These problems didn't ruin the experience, but they were a little annoying. With some bug fixes, performance could be even better. For now, we rate it 7.2 out of 10. |
| 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. | 8.8 Habitica's design is a breath of fresh air compared to most productivity apps. The retro pixel art and RPG theme make it feel playful and rewarding. The interface is colorful and lively, and we had a lot of fun customizing our avatars.
Sometimes the UI can feel a bit busy, and we'd love even more options for color coding and icons. But overall, Habitica's design is charming and makes habit tracking feel less like a chore. We rate it 8.8 out of 10. 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. Winner in this category | 7.5 Habitica is free to use, with optional in-app purchases for gems and subscriptions. Most features are available for free, and we never felt pressured to pay. Some of us wished there were more ways to earn premium currency without spending money, but overall, the value is fair—especially if you want a fun way to stay productive. We give value for money a 7.5 out of 10. |
| 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. Winner in this category | 7.8 Getting started with Habitica is pretty easy, and the game-like approach makes tracking habits feel less boring. Adding tasks, checking them off, and customizing your avatar are all simple. If you need a little extra motivation, this app really helps. There is a bit of a learning curve if you want to use all the features, and sometimes the interface can feel overwhelming at first. We also hit a few bugs and slow moments here and there. Once you get used to it, though, Habitica is user-friendly and rewarding. We'd love to see better onboarding and smoother performance, but overall, ease of use scores a 7.8 out of 10. |
| 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. Winner in this category | 7.0 Habitica says your data stays private and isn't sold to third parties, which is great. We didn't find much info about advanced privacy or security features, but we also didn't run into any issues. For most people, privacy is handled well, but if you have strict needs, you might want to look a bit deeper. We rate security and privacy at 7.0 out of 10. Winner in this category |
| Conclusion A summary of our findings and final thoughts for each app. | Merlin AI stands out as an exceptional all-in-one AI assistant that successfully combines multiple AI models with practical tools. The generous free tier makes it accessible to everyone, while the premium features offer significant value for power users. For anyone looking to consolidate their AI tools into one powerful platform, Merlin AI delivers an impressive and well-rounded experience. | If you want to make habit tracking more fun, Habitica is a great pick.
