### 5/5 — Great app

*2026-08-11*

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

**Developer response:** Thank you so much for the kind words! We’re glad you’re enjoying the clean experience. We’re constantly working to improve Fastly and add useful features while keeping it simple, focused, and clutter-free. Thanks for your support!

### 5/5 — Exactly what I was looking for

*2026-08-04*

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

**Developer response:** Thank you so much for the kind review! We’re glad you’re enjoying the straightforward fasting tracker and phase insights. Your support means a lot to us!

### 5/5 — Simple and efficient

*2026-08-03*

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!

**Developer response:** Thank you for such a thoughtful review—and for supporting us with a tip! We’re thrilled that you enjoy the clean, distraction-free experience, especially the Apple Watch complication. Feedback like yours motivates us to keep improving the app!

### 3/5 — Almost perfect, missing something useful.

*2026-06-24*

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.

**Developer response:** 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!

### 5/5 — Great Fasting Tracker!

*2026-06-17*

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.

**Developer response:** Thank you for your kind words! We’re so glad you’re enjoying Fastly’s simple design and that the Notes feature has been helpful. Thanks for your support!

### 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

### 5/5 — Follow up to past review

*2026-05-18*

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

**Developer response:** 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!

### 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!

### 3/5 — Missing Scheduled Reminders

*2026-04-21, version 1.3.8*

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

### 5/5 — Great app

*2026-03-24, version 1.3.7*

Simple, easy to use and great app
