About this app

PlainFasting is intermittent fasting and water tracking without the noise: one clean timer, one honest water tracker, and nothing you didn't ask for. Pick your eating window, drink through your day, and see everything logged exactly the way it happened.

NEW: HYDRATION

Track your water without the circus. A fill rises toward your daily goal, one tap logs a glass, and every drink sits in a log you can edit or delete. Millilitres or ounces — it uses your region's default. Take the sensible daily goal or set your own.

Water reminders that respect you: gentle nudges only during your waking hours, each carrying your real progress ("42 of 68 oz — a glass now keeps you on track"). No 3 AM buzz, no lighting up your phone, no watching an ad to log a sip. Off by default; on in one tap. Everything stays on your device.

FASTING, DONE PLAINLY

1. Pick a rhythm — 16:8, 18:6, 19:5, 20:4, OMAD, or slide to your own window. Tap any preset to see what it's actually good for. Change it anytime.

2. Live your day — the timer flips between fasting and eating at your planned times. Eating early or late? One tap tells the app what really happened — today bends, not forever. Done eating early? Your next fast starts now, extra hours credited. First bite an hour in? Log it and the fast gets its true length.

3. See it logged honestly — every fast lands in History with its real times. Streak, best run, 7-day average, and a calendar of goal-met days. Made a mistake? Edit a fast's times, or long-press to delete. Honest logging includes corrections.

EXTENDED FASTS

Some days deserve a longer fast. Schedule a one-off 24, 48 or 72-hour fast on top of your daily plan — free. The planner shows exactly when it starts, when the goal is met, and when your first meal opens. Bail out anytime, logged honestly: "31h of 48h." A repeating weekly rhythm is Pro.

WHY PLAIN?

• No account. Your data lives on your device and never leaves it.
• Works offline. It's a timer and a tracker, not a cloud service.
• Honest guides built in: "What can I drink?", "One meal or many?", and "Losing fat?" — plain words, no lectures, no prescriptions.
• A home-screen widget that shows your phase and when it flips — a real clock time, never a stale countdown.
• Light and dark themes, free.

PLAINFASTING PRO — ONE SMALL YEARLY PRICE. CANCEL ANYTIME.

Everything that matters is free, forever. Pro removes all ads and unlocks weekly extended-fast schedules, the Wear OS watch tile, accent colors, and CSV export & import — for one small yearly price. Cancel in two taps; you keep the free app either way. No trial traps. Bought the original one-time Pro? You keep it forever.

THE HONEST PART

Most fasting and water apps make you watch an ad for every tap, wake your phone at night, rent you your own data, or lock streaks behind a paywall. PlainFasting does none of that. Fast, hydrate, and see what you actually did. That's the whole job, done properly.

Supports Android phones and Wear OS 3+ watches (Galaxy Watch 4 and newer, Pixel Watch).
