PlainFasting

The honest fasting timer.
Now it tracks your water, too.

Pick your eating window, log your water, and see every fast and every glass exactly the way it happened — no ads on every tap, no 3 AM nudges.

How it works

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. Set when your first meal usually lands. Change it anytime, no lectures, no lock-in.

2

Live your day

The timer runs itself. Eating early or late? One tap tells the app what really happened, and your schedule bends for today — not forever.

3

See it logged honestly

Every completed fast lands in History with its real length. Streak, best, 7-day average — computed from what you did, not what you promised.

New in 0.7

Now it tracks your water, too.

Fasting's other half, done with the same restraint. A fill rises toward your daily goal, one tap logs a glass, and every drink sits in a log you can edit.

  • One tap to log — never an ad to mark a glass of water.
  • Reminders only during your waking hours, each carrying your real progress. No 3 AM buzz, no lighting up your phone.
  • Millilitres or ounces — it picks your region's default.
  • Edit or delete any drink. Off by default; on in one tap.
  • All on your device. No account, nothing to sign up for.

The app

Plain to look at. Plain to use.

One ring, one number, one button. Reminders arrive when your window opens and closes — with a heads-up you control, down to none at all.

FAQ

Fair questions.

Why should I trust the pricing?

Because it's stated plainly and it behaves plainly. Pro is $2.99 a year — about the price of one coffee — and cancelling takes two taps in Google Play. No trial that quietly converts, no price that jumps after a teaser period, no features held hostage. If you cancel, you keep the entire free app: timer, plans, reminders, widget, history. And if you bought Pro back when it was a one-time purchase, you keep it forever — a promise made is a promise kept.

Do I need an account?

No. There's nothing to sign up for. Your data lives on your device and never leaves it.

What if I eat outside my window?

Tap "I'm eating now." Your window shifts for today, the fast you just finished is logged at its real length, and tomorrow the plan is back to normal. The app records what happened — it doesn't scold you about it.

Which devices are supported?

Android phones, with a home-screen widget included. The watch tile supports Wear OS 3 and newer (Galaxy Watch 4 and up, Pixel Watch).

What data do you collect?

Your fasting data: none — it stays on your device. The free version shows ads via Google AdMob, which involves standard ad-network identifiers; going Pro removes ads entirely. Details in the privacy policy.
