About this app

FastR is a minimalist fasting tracker built to do one thing well: track your fasts. Just open it, start your fast, and go.

Why you'll like it:

• No ads - ever. Nothing to interrupt you, nothing to click away.

• No internet required - FastR works fully offline. No connection, no problem.

• Your data stays with you - everything is stored locally on your device. No accounts, no sign-ups, no cloud, no tracking.

• Dead simple - start and stop your fast with a tap. That's it.

• Recent history - keeps your last 30 fasting records so you can see how you're doing without drowning in old data. Don't focus on history analysis. Focus on your goals that are in front of you.

• Desktop widget available


FastR is for people who want a clean, honest fasting timer without the subscriptions, notifications, and feature creep of other apps. If you've been looking for something that just tracks your fasting and then gets out of your way, this is it.
Simple intermittent fasting tracker. No ads, no account, works fully offline.
