Just Fast - Fasting Timer

Intermittent Fasting Tracker

Features & Capabilities

The only fasting app with eating window countdown. See fat burning, ketosis & autophagy phases.

Just Fast is the intermittent fasting timer that tracks both your fast and your eating window — a combination no other fasting app offers.

Whether you're new to 16:8 or pushing into 20:4, OMAD, or custom schedules, Just Fast gives you a clear, distraction-free timer alongside the insights to understand what your body is doing and build habits that stick.

EATING WINDOW COUNTDOWN — ONLY IN JUST FAST Most fasting apps tell you when your fast ends. Just Fast also tells you when your eating window closes. Know exactly how much time you have left to eat, so you stop overrunning your window by accident.

UNDERSTAND YOUR FAST, NOT JUST YOUR TIMER

Just Fast visualizes the metabolic phases of fasting as they happen: fat burning begins around hour 12, ketosis deepens past hour 18, autophagy activates beyond hour 24. You do not need a biology degree — the app shows you where you are and what your body is doing.

Note: The app is free with light banner ads on secondary screens (history, settings). The main fasting timer screen is completely ad-free.

User Reviews

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.

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!
