CoFasting 16:8 Fasting Tracker

CoFasting is a fasting timer built for two. You and one other person, on the same ring.

Send an invite by iMessage or AirDrop and they are in within seconds — no account, no email, no password, ever.

BUILT FOR TWO, NOT FOR ONE
A fasting tracker is usually a solo screen. CoFasting starts from the opposite idea: the person doing it with you should be right there on the ring.

• One invite, sent the way you already text
• Both timers on a single ring, refreshed about once a minute while the app is open
• See when they start, when they are close, when they finish
• Remove a partner at any time, from either side
• If you have Plus, your partner never needs to buy anything

SHARING WITHOUT A SIGNUP
Sharing normally means creating an account first. CoFasting uses your own iCloud to link the two of you, so there is nothing to create and nothing to remember. Your fasts live on your device and in your private iCloud. We do not run a server that holds them, because there is no account to hold them against.

SIX SCHEDULES
12:12, 14:10, 16:8, 18:6, 20:4 and 23:1 — one meal a day. 16:8 is included for everyone. Switch whenever your week changes — travel, a late dinner, a slow Sunday.

A LAP, NOT A LECTURE
Pip walks your fasting window like a running track and passes checkpoints along the way: Fed, Glycogen, Ketosis, Autophagy. The checkpoints are time-based educational estimates, meant to make the hours more interesting to watch. They are not measurements of your body.

FOOD NOTES, ON DEVICE
Describe what you ate in plain words and Apple Intelligence turns it into an estimated calorie and macro entry, entirely on device. Nothing is uploaded anywhere. Values are estimates — edit any number you disagree with. Without Apple Intelligence, a built-in food table makes the estimate instead.

WHEN THE TIMER ENDS
An alarm you will actually hear, even with the ringer off. Checkpoint notifications while the clock runs. A Home Screen widget and a Live Activity so the ring is one glance away.

YOUR DATA STAYS YOURS
• No account, no signup, no email address
• No third-party analytics servers
• Everything on device and in your own iCloud
• CSV export and import, in every version

COFASTING PLUS
Included for everyone: the 16:8 schedule, the timer, your full history, food notes with no limit, the widgets, the Live Activity, and CSV export.

Plus unlocks the other five schedules, the silent-mode finish alarm, and laps that start themselves the moment your eating window closes — and lets you invite a partner, who never needs to buy anything. Accepting an invitation never requires Plus.

CoFasting Plus is offered as a 3-month or 12-month auto-renewing subscription, or as a one-time purchase.

Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel in your Apple Account settings.

BEFORE YOU START
CoFasting is a timer and a tracking tool. It does not provide medical advice, diagnosis or treatment, and the checkpoint labels are educational estimates rather than readings from your body. Talk with a qualified health professional before changing how you eat — particularly if you are pregnant or breastfeeding, under 18, taking medication, living with a medical condition, or have a history of disordered eating.
