Fasting hours you can actually see, a window that bends to your day, a history that stays yours — no pressure, no guilt, no punishment for stopping early.
Postivo is an intermittent fasting timer for people who want calm, steady progress — without pressure tactics, guilt, or punishment for ending a fast early.
It's 7 p.m. and dinner ran late. Most trackers answer with a red screen and a broken streak. Here you shift your window and carry on — the streak was never the point. The hours are, and the trend you get to watch settle.
FEATURES
→A window that bends to your day
16:8, 18:6, or hours you set yourself — or a few questions about when you really eat, and the protocol comes back built around your life.
→See what the hours are doing
The stage timeline shows what your body typically moves toward — fat-burning, the onset of ketosis, autophagy — in sourced, hedged wording, because timings vary from person to person.
→Progress you can look at
Fasts, weight, and water land in one history, so weeks of effort become a line you can read instead of a feeling you have to trust.
→Reminders that respect your evening
A nudge when your window opens and closes, silent through the quiet hours you choose. Never enough to feel supervised.
→Automatic iCloud backup, included for everyone
Everything backs itself up with no subscription needed, so a new phone never costs you your history.
→More depth when you want it (Postivo Pro)
Apple Health sync, a live fasting ring on your Home Screen, advanced statistics, and a glucose and ketone log — the full picture of what your fasting hours are actually doing for you.
WHY POSTIVO
→ Honest by default — no countdown pressure, no dark patterns, no shame when a fast ends early
→ Nothing punishes you for stopping — end when you need to, log it, move on
→ Visible close buttons — every offer screen has an obvious way out
→ Your data stays yours — iCloud backup for everyone, Health export (Postivo Pro)
→ A window you manage, not endurance you test — fasting without the drama
Own your window. Watch it work. Feel steady.
SUBSCRIPTION INFORMATION
Postivo Pro is an auto-renewable subscription or a one-time purchase. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the current period ends; the renewal charge falls within those 24 hours. Manage or cancel in your Apple Account settings. Any unused trial period is forfeited on purchase.
DISCLAIMER
Postivo is a tracking tool, not a medical device, and nothing in it is medical advice. Stage information is educational and timings vary per person. Talk to a doctor before starting or changing a fasting routine — especially with a medical condition, medication, pregnancy, or a history of disordered eating.
