Postivo is an intermittent fasting timer for people who want calm, steady progress β€” 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 β€” the streak was never the point. The hours are, and the trend you get to watch settle. FEATURES β†’A window that bends to your day 16:8, 18:6, or hours you set yourself β€” or a few questions about when you really eat, and the protocol comes back built around your life. β†’See what the hours are doing The stage timeline shows what your body typically moves toward β€” fat-burning, the onset of ketosis, autophagy β€” in sourced, hedged wording, because timings vary from person to person. β†’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. β†’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. β†’Automatic iCloud backup, included for everyone Everything backs itself up with no subscription needed, so a new phone never costs you your history. β†’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 β€” the full picture of what your fasting hours are actually doing for you. WHY POSTIVO β†’ Honest by default β€” no countdown pressure, no dark patterns, no shame when a fast ends early β†’ Nothing punishes you for stopping β€” end when you need to, log it, move on β†’ Visible close buttons β€” every offer screen has an obvious way out β†’ Your data stays yours β€” iCloud backup for everyone, Health export (Postivo Pro) β†’ A window you manage, not endurance you test β€” 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 β€” especially with a medical condition, medication, pregnancy, or a history of disordered eating.
