Fasting Tracker - List Fast

Your fast, your phone, nowhere else - a private, offline intermittent-fasting timer.

List Fast is a fast, no-nonsense fasting timer and log. Pick a protocol, tap Start, and watch an honest progress ring count up - no account, no cloud, and nothing you log is ever uploaded.

★ START IN ONE TAP

• 16:8, 18:6, 20:4 and OMAD presets, or set your own custom length

• The timer is based on the real clock, not a countdown that resets if your phone restarts - close the app, reboot, come back a day later, it is still exactly right

• Edit a fast's start or end time afterwards - perfect for the days you forgot to press Start

★ A CLEAR PICTURE OF WHERE YOU ARE

• A live progress ring shows elapsed and remaining time at a glance

• A plain-language stage timeline (Fed, Early Fast, Fat-Adapting, Deep Fast, Extended Fast) - general background information only, never a claim about what your own body is doing

• General information only, never medical advice - see the in-app disclaimer

★ HISTORY THAT MEANS SOMETHING

• Every fast logged with duration and completion percent

• A current streak, plus weekly and monthly summaries

• Nothing is ever deleted unless you choose to

★ GENTLE, BATTERY-FRIENDLY REMINDERS

• Optional nudges for "fast complete" and "eating window closing"

• Both are inexact by design - a reminder a few minutes late costs nothing, and the app never requests the exact-alarm permission

★ YOUR DATA STAYS YOURS

• Works 100% offline - internet is used only to show ads

• No account, no cloud, no tracking of your fasting schedule

• Android cloud backup is switched off on purpose: your data never leaves the device

• Export a readable JSON backup of every fast and import it back any time - never locked behind a paywall

★ MADE TO FEEL GOOD

• No banner ads. Ever. Nothing sits on top of your ring or your timeline

• Material You design that follows your wallpaper, light and dark themes

• Prefer no ads at all? Watch one short video and go ad-free for 24 hours

List Fast needs an internet connection only to show ads. Starting and stopping a fast, the timer, the stage timeline, history, reminders, export and import all work in airplane mode.
