AllyFast is only 0.99 and provides all the features of the more expensive apps. It's perfectly simple and informative. A huge thanks to the developer. My only requests are a future dark mode and the new iOS 26 design. **Developer response:** Thanks so much for the review! I first built this app just for myself with one simple idea: fasting apps shouldn’t need subscriptions. It makes me so happy to see so many people using it and finding it helpful. Reviews like yours really mean a lot. And yes - dark mode and the new iOS design are on the way! ### 5/5 — Easy!! *2025-07-14* Solid as app all you need to start the journey or continue ur journey without all the corney things other apps offer would highly recommend **Developer response:** Thanks!! Reviews like this really motivate me to keep maintaining and improving the app. I’m planning to spend more time on updates, and you’ll be seeing some new features soon! ### 5/5 — Love It! *2025-06-02* As simple as it gets and love that it doesn’t track my data. No ads, no subscription it really doesn’t get better than that!! Hoping it could eventually have the option to do a custom fast or even a 24, 48, or 72 hour option :) **Developer response:** Thanks for the great review and feature ideas! Users like you are the reason I’m doing this. As I mentioned before, I’ll be adding your suggestion - custom fasts and fasts longer than 24 hours - in the next version! ### 5/5 — What a great app! *2025-05-10* Simple, effective, no ads and no subscription. Exactly the app I’ve been looking for. Great!!!! **Developer response:** Thanks! A new update is coming soon. I’m also open to new feature ideas - I’ll implement them even if just one person asks!! ### 5/5 — Love it! *2025-04-09* Simple, effective, I love this app **Developer response:** Thanks for the comment! This is just the beginning. We’ll keep updating as we build our user base!! ### 5/5 — Finally, a fasting app that’s clean and motivating! *2025-04-05* I’ve tried a bunch of fasting apps, but AllyFast is by far my favorite. No ads, no annoying popups—just a simple, beautiful timer that helps me stay focused. I love how it shows when fat burning and ketosis kick in, and the little confetti when I hit my goal is such a nice touch. Perfect for anyone who just wants to track fasting without the clutter.
