QoFast: Intermittent Fasting
Extended Fasts & Ketosis Timer
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
New: watch 13 metabolic milestones unlock in real time, from fat burning to autophagy. The only app built for both 16:8 and multi-day extended fasts. 7-day free trial.
Tired of dieting without results? Lose weight naturally with intermittent fasting instead of counting calories, and go further than any other app when you're ready.
THE ONLY APP FOR BOTH INTERMITTENT AND EXTENDED FASTING
QoFast is built for the full journey: daily 16:8 windows AND multi-day extended fasts with a guided Prep > Fast > Refeed structure. Most apps stop at 24 hours. QoFast safely takes you to 3, 5, even 7 days.
SEE YOUR METABOLISM IN REAL TIME
Watch your body move through 13 milestones as you fast: Fed > Fat Burning (4h) > Ketosis (12h) > Autophagy (24h) and beyond. Real-time metabolic-zone education tells you exactly what's happening inside you, with milestone notifications at every stage.
