FASTING FOR SHIFT WORKERS
Night shifts and early shifts make a fixed 16:8 hard. Snap your roster and FairFast moves your eating window around your shifts, day by day, without making any fast longer than your goal.
OUR PLEDGE
What's free today stays free: the timer, your full history, widgets, and every fasting schedule from 13:11 to 72h+. Your data is yours. Export it any time, free. You can always pay once instead of subscribing.
PRIVATE BY DESIGN
Your fasting log stays on your phone. No sign-up, no ads, and we never see your fasting log. Pro photo checks send only the photo you choose, after you agree, to Google Gemini to be read. We never keep it.
FairFast is a tracking tool. It is not a medical device and does not diagnose, treat, cure, or prevent any condition. Talk to a healthcare professional before fasting.
