PlainFasting is intermittent fasting without the noise: one ring, one number, one button. Pick your eating window, live your day, and see every fast logged the way it actually happened.
THREE THINGS. THAT'S THE WHOLE APP.
1. Pick a rhythm
16:8, 18:6, 19:5, 20:4, OMAD — or slide to your own window. Set when your first meal usually lands. Change it anytime. No lectures, no lock-in.
2. Live your day
The timer runs itself, flipping between fasting and eating at your planned times. Eating early or late? One tap tells the app what really happened — your schedule bends for today, not forever. Done eating early? Your next fast starts immediately, and you get credit for the extra hours. First bite came an hour into your window? Log it, and the fast gets its true length.
3. See it logged honestly
Every completed fast lands in History with its real length and its real times. Streak, best run, 7-day average, and a calendar of goal-met days — computed from what you did, not what you promised. Made a mistake? 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 tells you exactly when it starts, when the goal is met, and when your first meal opens. No surprises. Bail out anytime with one tap and it's logged honestly: "31h of 48h." Want a weekly rhythm — say, 24 hours after Wednesday and Friday? That's Pro.
WHY PLAIN?
• No account. Nothing to sign up for — your data lives on your device and never leaves it.
• Works offline. It's a timer, not a cloud service.
• Honest answers built in: "What can I drink?" and "One meal or many?" guides — plain words, no lectures.
• Reminders that respect you: a heads-up when your window opens and closes, with lead times you control — down to none at all. Off by default.
• A home-screen widget that shows your phase and when it flips — as a real clock time, never a stale countdown.
• Light and dark themes, free.

THE HONEST PART
Most fasting apps upsell you coaching plans, lock streaks behind paywalls, or rent you your own data back. PlainFasting does none of that. It tells you when your window opens, when it closes, and what you actually did. That's the whole job, done properly.
