| 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 | 9.0 HabitNow delivers a comprehensive set of features for habit and routine tracking. We especially appreciate the flexible scheduling options—daily, weekly, monthly, and custom routines—which make it easy to adapt the app to any workflow. Widgets and reminders are reliable, and the built-in timer and Pomodoro tools are a great boost for productivity. Progress tracking is motivating, with detailed stats and streaks that help keep us on track. The free version covers most basic needs, though it does limit the number of habits and tasks you can track. Upgrading to premium unlocks unlimited habits, advanced customization, and additional widgets. While we'd like to see features like account sync and even more robust alarm reliability, HabitNow offers an impressive feature set for both new and experienced users. Winner in this category |
| 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. | 9.0 HabitNow performs reliably in daily use. The app is fast, responsive, and stable, even when tracking a large number of habits and tasks. We experienced smooth navigation and quick loading times throughout our testing. While there are occasional reports of alarms or notifications not firing as expected, and some widget update quirks, these issues are relatively rare and do not significantly impact the overall experience. HabitNow delivers strong performance for a productivity app of its kind. Winner in this category |
| 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 Design is one of HabitNow's standout qualities. The interface is clean, modern, and easy to navigate, making it simple to set up and manage habits or routines. We enjoyed the customizable themes and icons, which allow for a personalized look and feel. Widgets are visually appealing and integrate well with the Android home screen. While we'd love to see even more color options and better support for system fonts or accessibility settings, the overall design is both attractive and highly functional. HabitNow strikes a great balance between aesthetics and usability. 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. | 9.5 We think HabitNow offers excellent value for money, especially with its one-time premium upgrade that unlocks unlimited habits, advanced customization, and additional widgets. The free version is generous enough for most users to get started, and there are no ads or forced subscriptions. Compared to other habit trackers that require ongoing payments, HabitNow's pricing model is refreshingly fair. While some may wish for a slightly higher free limit, the premium upgrade is well worth it for anyone serious about habit tracking and productivity. 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. | 9.3 We found HabitNow remarkably easy to use, with a clear and intuitive interface that makes setting up habits and routines quick and painless. Adding, editing, and organizing tasks is straightforward, and the onboarding process is smooth for new users. Widgets and reminders are easy to configure, and the app's layout keeps everything accessible without clutter. There are a few minor quirks, such as needing to manually mark tasks as done after using the timer, or occasional confusion with backup and import features. However, these do not detract significantly from the overall experience. HabitNow is a great choice for anyone looking for a straightforward and effective habit tracker. 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 We appreciate that HabitNow takes privacy seriously by storing your data locally on your device and not requiring an account for basic use. The lock screen feature adds an extra layer of privacy for sensitive routines and notes, and backups can be created and exported manually, giving you full control over your data. While some may wish for account-based sync or cloud backup, the current approach ensures your information stays private. There are no intrusive ads or unnecessary permissions, making HabitNow a trustworthy choice for privacy-conscious users. Winner in this category |
