It also tells you (accurate) phases of fasting like fat burning and ketosis. It doesn’t seem to automatically log a fast like so many do without you doing it yourself (I often start at different times or skip a day and hate when my phone tells me I fasted when I didn’t). It lets you edit the fast start and end time, which many do not. It gives a clear, easy to understand graph of data to look back on your fasts. There is an option to pay if you like which I happily did mostly because it was optional. Lastly, there is a 2x2 widget which was important to me. It’s missing a few common fasting plans that span multiple days but that’s not something I do often so doesn’t matter too much. Would be neat if it had a way to integrate weight and body fat percentage from Apple Health or even blood ketones from KetoMojo so you could see how they correlate but sometimes less is more. Overall very happy! ### 5/5 — Simple App, Responsive Developer *2026-02-20, version 1.3.4* I love a simple app that just works! Fastly will help you stay on top of your fasting with a clean interface and easy to understand language for those new or experienced with fasting. I had a suggestion for the app and the developer responded and implemented the change within the week! I will always support a small time developer over another app from Meta and this app is one that really works and I can rely on! ### 5/5 — Simple & Perfect *2026-02-18, version 1.3.4* Appreciate to do a live activity to show on lock screen & notification for water intake and starting and ending of the fast, please. ### 5/5 — Best FREE fasting track out there *2026-02-14, version 1.3.4* I love it and the widget is perfect 💛 ### 5/5 — Easy to use *2026-02-10, version 1.3.3* Very easy to use, simple and easy to ### 5/5 — Great app *2026-02-04, version 1.3.3* Works well and has a lot of features! ### 5/5 — Simple and easy *2026-01-27, version 1.3.2* Intermittent fasting made simple. This app has made sticking with my program a lot easier. I highly recommend. ### 5/5 — Amazing *2026-01-26, version 1.3.2* It’s so beautiful and easy to use. I hope it gets a lot of people to use it. ### 5/5 — Great app *2026-01-23* Simple, easy to use and great app **Developer response:** Thank you, Bahar Lawter! We're so glad you're finding the app simple and easy to use. That’s exactly what we aimed for. Happy fasting! ### 5/5 — Awesome *2026-01-16, version 1.2.2* Great way to keep within the time zones required for intermittent fasting ### 5/5 — Very good *2026-01-15, version 1.3.0* Brill ### 5/5 — Really great *2026-01-11, version 1.2.1* I like how simple this app is. Some fasting apps have gotten way too complex and this keeps it really simple. One suggestion would be I would really like to see is when clicking on the fasting timer, that it switches to a countdown of time remaining in the fast. Also put the time the fast is over near the countdown somewhere! That would make this perfect! Great job Dev. ### 5/5 — Super easy and straightforward *2026-01-10, version 1.2.1* Wanted a simple app that tracked my feeding/fasting times with light descriptions of the fasting phase. Perfect for my needs!! ### 5/5 — Great fasting app *2026-01-10, version 1.2.1* I recently got this app after leaving another app that was so complicated and so many different issues so far this has been very easy. No issues I get my notification went to fast went to stop fasting. So I have no complaints. ## Most critical reviews (10 lowest-rated) ### 3/5 — Almost perfect, missing something useful. *2026-06-24, version 1.3.14* This app is well designed and works very well for tracking fasts. It just needs the ability to track weight daily since managing weight is one reason someone may be fasting. If that was added, this app would be perfect. ### 3/5 — Missing Scheduled Reminders *2026-04-21, version 1.3.8* It’s a decent app but missing scheduled reminders and watch complications. ### 4/5 — No bs, just fasting *2026-06-05, version 1.3.12* Unlike other app no bs. Only reason for 4 not 5 is I want 20+ hour fast info ### 4/5 — Great just needs Apple Watch widget *2026-05-07* Works great, simple and informative. I just wish it had an Apple Watch widget to look down on my watch and see how much time is left till fast is over. **Developer response:** Thank you for the thoughtful feedback. We’re glad you’re enjoying the app’s simplicity and usefulness. An Apple Watch complication for quickly viewing fasting progress and remaining time is a great suggestion, and it’s something we’re considering for a future update. Appreciate you taking the time to share this with us! ### 4/5 — Almost perfect *2026-01-22, version 1.3.1* I literally have 10 fasting apps currently downloaded trying to find the perfect one. I love the format of yours and how easy it is to edit your fasts as far as start and end. My only suggestion would be to add some graphs. I would like to be able to track my weight as well as see all of previous fasts. I want to be able to track how many hours I’ve fasted for the week, month, etc. if you made those changes this would 100 percent be a 5 star and your app would be the one I’m using. For now I will keep looking but still a great basic app for fasting. Would recommend to anyone that is just simply wanting to track fasts and nothing else. It’s a very simple and straight forward app. ### 4/5 — Love the Simplicity *2026-01-19* This app gets right to why you would download it…starting, tracking, and ending your fast! I love the UI, it’s clean and shows you exactly what you need when you need it. My only reason for 4 stars is the timing given to users is incorrect for fat burning and such than what is proved by science. I suggest this be fixed and the app gain a few more features like tracking if you worked out during a fast and if that accelerated your fasting timeline. **Developer response:** Thank you for the detailed feedback, JoeSpecific629! We're thrilled that you love the clean UI and simplicity—that’s exactly what we’re striving for. You make a great point about the fasting phase descriptions. We are currently reviewing our data to ensure it aligns more closely with the latest metabolic science. Also, the idea of tracking workouts and their impact on the fasting timeline is fantastic—I've added it to our development roadmap! We’d love to earn that 5th star from you as we continue to improve. Thanks for helping us grow! ### 5/5 — Great app *2026-08-11, version 1.3.21* Very clean and attractive interface and devs that are constantly updating with new features. One of the better fasting apps available now. ### 5/5 — Exactly what I was looking for *2026-08-04, version 1.3.20* A straight forward and functioning fasting tracker that includes phases without a subscription pay wall. ### 5/5 — Simple and efficient *2026-08-03, version 1.3.20* The app is simple but has all the functions I need. It’s clean and aesthetically pleasing, without any distracting ads or constant prompts to spend money (although you can send a tip if you’d like to show support). The developers clearly respond to feedback and strive to improve the app. The Apple Watch complication is my favorite feature: it’s easy to tell what phase of the fast I’m in or how much time I have left in my eating window. In my opinion, this is the best fasting tracker app. I ended up sending a tip to support the development of this app, I like it so much! ### 5/5 — Great Fasting Tracker! *2026-06-17, version 1.3.14* Works well! I actually like it better than different app I downloaded that wants me to pay a subscription fee to use a bunch of features I don’t really need. Fastly’s interface is sleek and easy to figure out. Logging fasts only takes a few seconds. This is great since I use it every day where having to click through multiple things gets old fast. I also love that they added a notes section so you can keep a diary on how each fast went. This is helpful especially for longer fasts as a newcomer; I can keep a record of where I struggle so I know to what to avoid or improve. ## Most praised reviews (6 highest-rated) ### 5/5 — Follow up to past review *2026-05-18, version 1.3.12* Fixed to the small complaint I had about the app. Added an Apple Watch widget. Everything is perfect now thank you! ### 5/5 — Great app *2026-03-24, version 1.3.7* Simple, easy to use and great app ### 5/5 — One Suggestion! *2026-03-16, version 1.3.5* I supported with $10 cause I just love this design! My one only suggestion is adding below the timer when the fast actually ends. It only shows when I started the fast. Showing when my fast ends helps me plan my next day. Thank you again for such an amazing app! ### 5/5 — Simple, Good, to the Point *2026-03-11, version 1.3.5* Perfect App for fasting. Allow us to change the colors of the “Custom” Plan! ### 5/5 — Simple, Good, to the Point *2026-02-27* Perfect App for fasting **Developer response:** Thank you so much! We’re really glad the app feels perfect for your fasting routine. Keeping it simple, accurate, and easy to use is exactly what we aim for. Appreciate your support! ### 5/5 — Amazing interface with everything that I need at my finger tips. Widget too! *2026-02-22, version 1.3.4* I love the interface and even better is the widget. My only suggestions: a widget for the lot screen would be great, as well as the projected end time during the fast window. Eg in addition to the countdown, it’ll give me the ETA. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
