Great app

Very clean and attractive interface and devs that are constantly updating with new features. One of the better fasting apps available now.

Exactly what I was looking for

A straight forward and functioning fasting tracker that includes phases without a subscription pay wall.

Simple and efficient

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!

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.

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.

No bs, just fasting

Unlike other app no bs. Only reason for 4 not 5 is I want 20+ hour fast info

Follow up to past review

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

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.

Response from developer

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.

Great app

Simple, easy to use and great app

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!

Simple, Good, to the Point

Perfect App for fasting. Allow us to change the colors of the “Custom” Plan!

Simple, Good, to the Point

Perfect App for fasting

Response from developer

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!

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!

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!
