FastKeep: Fasting Timer

Private fasting & streak timer

Only for iPhone

$4.99

iPhone

Pay once, keep it forever. No subscription, no account, no tracking. Your fasts and streaks live on your phone — and nowhere else. FastKeep is a simple, private timer for two things people actually stick with: fasting windows and quitting streaks. Start a fast and watch the timer run. Break a habit and watch the streak grow. That's it — no accounts, no cloud, no ads, and nothing to subscribe to. WHY FASTKEEP • One-time purchase. Pay once and it's yours, including updates. No subscription — ever. • Truly private. Everything is stored on your device. FastKeep makes no network requests, has no analytics, and never sees your data. • Fasting timer. Track 16:8, 18:6, OMAD, or any custom window. See elapsed and remaining time at a glance. • Elimination streaks. Quitting sugar, alcohol, nicotine, or anything else? Track the days since you stopped, and keep the chain going. • Backup on your terms. Export your data to a file whenever you want; import it on a new phone. You hold the backup, not us. • Designed for focus. A clean, dark interface that shows what matters and stays out of the way. NO CATCHES No account to create. No email to hand over. No "premium" tier hiding the good features. No data leaving your phone. If you've had enough of subscription apps that track everything, FastKeep is the opposite of that. Note: FastKeep is a timer and tracker only. It does not provide medical advice. Consult a health professional about whether fasting is right for you.
