Almost perfect, missing something useful.

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.

Thank you for the thoughtful feedback! We’re glad you’re enjoying the app. Weight tracking is currently in development and will be included in our next update. We hope you’ll enjoy the new feature!

Great Fasting Tracker!

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.

Fixed to the small complaint I had about the app. Added an Apple Watch widget. Everything is perfect now thank you!

Thank you so much for the updated review! We’re really glad the Apple Watch complication completed the experience for you. Enjoying fasting progress right from the watch face is exactly the kind of simple convenience we hoped to bring. Appreciate your support!

Great just needs Apple Watch widget

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.

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!

Missing Scheduled Reminders

It’s a decent app but missing scheduled reminders and watch complications.

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!

One Suggestion!

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!

Amazing interface with everything that I need at my finger tips. Widget too!

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.

Everything I was looking for in a keto app - if only all apps were this good.

This is a simple, free, minimalist appearing app that checked all my boxes for an app that logs a fast, shows you how long you’ve been fasting and how long you have left as well as how long over your target fast you are. 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!

Thank you for the incredibly thoughtful review. We’re glad the simplicity, accuracy, and manual control stood out — that’s exactly what we aim for. We appreciate your support and your ideas for future improvements.

Simple App, Responsive Developer

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!

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!

Simple & Perfect

Appreciate to do a live activity to show on lock screen & notification for water intake and starting and ending of the fast, please.

Almost perfect

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.

Thank you for such a thoughtful and detailed review — and for trying so many fasting apps to find the right fit. I’m really glad you found the app easy to use, especially the flexibility around editing fast start and end times. That simplicity is very intentional. Your suggestions around graphs, weight tracking, and viewing fasting totals (weekly/monthly hours and history) are excellent and already on my roadmap. Those insights would add meaningful value without compromising the app’s lightweight, straightforward nature. I truly appreciate you taking the time to share this feedback and to recommend the app for users who want a simple, no-frills fasting tracker. I hope to earn that 5-star rating in a future update. Thanks again for giving it a try.
