## What is Intermittent Fasting?

Free · Works offline · No account needed.

JustFast is a simple intermittent fasting app and fasting timer for everyday use. Pick a 16:8, 18:6 or OMAD plan, tap start, and see how much time is left of your fast and of your eating window. No account and no long setup: your first fast starts in seconds.

New to intermittent fasting? A plan like 16:8 means 16 hours of fasting followed by an 8-hour eating window. Many beginners start with 12:12 or 14:10 and move to 16:8 or 18:6 when it feels comfortable. JustFast explains each plan in plain words and lets you switch at any time.

### 5/5 — Destined to become my only fasting app

*2025-10-26*

This app is fairly new, but even so has a lot of great aspects to it. I’m new the fasting, but I’ve used this to track my two fasts and found it very easy to use, I’ve even managed to get my wife to use it.
Outside of the app one thing that I thoroughly am impressed with is the response you get back from the developer. He’s still designing the app as well as adding elements that people using the app for asking for. This will very quickly become my one and only fasting app.

### 5/5 — Easy to use.

*2025-10-26*

Really like the design of this app. It took me a couple of seconds to get used to how you set or adjust the time, but once I figured it out, I really like it! Thank you!
