Moonfast

Moonfast is a quiet intermittent-fasting timer for people who would rather not
be shouted at by an app.

Pick a protocol — 16:8, 18:6, 20:4, OMAD, or your own hours — and start. The
ring shows how far into your fast you are, and keeps counting if you go past
your goal.

LIVE ON YOUR LOCK SCREEN
Start a fast and it appears as a Live Activity, so the timer is there without
unlocking. The Dynamic Island keeps it at a glance, and Home and Lock Screen
widgets show your current fast, your streak and your longest fast so far.

A GENTLE STAGE TIMELINE
As the hours pass, Moonfast describes the stages people commonly associate with
fasting windows. It is written to be interesting, not instructive — bodies
differ, and the app says so.

YOUR HISTORY, HONESTLY
A calendar of the fasts you have finished, current and longest streaks, weekly
averages and personal bests. When there is not enough data yet for a number to
mean anything, Moonfast says that instead of inventing one.

WEIGHT, SMOOTHED
Log your weight, or connect Apple Health and let it come across on its own.
Moonfast draws a smoothed trend line through the daily noise, because day-to-day
weight moves on water alone. Connecting Apple Health is optional, and the app
works fully without it.

VITALS, SIDE BY SIDE
If Apple Health has your resting heart rate, heart rate variability or time
asleep, Moonfast charts them next to the days you fasted. It shows the
readings; it does not tell you what they mean. Readings come from an Apple
Watch or another app — Moonfast only reads them.

HYDRATION
Log water, tea or coffee while you fast. If you want a daily target you can set
one — Moonfast will not pick one for you.

PRIVATE BY DEFAULT
No account. No servers. No analytics. Everything you log stays on your iPhone,
and you can export all of it as JSON or delete every trace of it whenever you
like.

Moonfast is a timer and a log. It is not a medical device, and it does not give
medical advice, diagnosis or treatment. Talk to a doctor before you change how
you eat, especially if you take medication or have a health condition. Moonfast
is not intended for anyone under 18, for anyone who is pregnant or
breastfeeding, or for anyone with or recovering from an eating disorder.
