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.

List Fast is a timer and a log and gives no nutrition advice. It is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a healthcare professional for medical advice, diagnosis, or treatment. Fasting is not right for everyone - see the in-app disclaimer, and check with a doctor if you are pregnant, have a history of an eating disorder, have diabetes, or take regular medication.

Recent changes:
• Settings › About fasting & your health now says in full what this app is not: List Fast is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a healthcare professional for medical advice, diagnosis, or treatment. The store listing already said so; now the app does too.
• That note now scrolls, so a large display font cannot cut the end of it off.
