# FairFast

> FairFast is an honest intermittent fasting tracker and fasting timer for iPhone and Android. No ads, no account. The timer, every schedule, widgets and the full history are free, and the developer pledges they stay free. Your fasting log is stored on your phone; the developer never sees it.
