PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. When will I ovulate? Enter your last period start date and your typical cycle length — OvuWatch calculates your estimated ovulation day (cycle length minus 14) and your six-day fertile window, and paints both onto a colour-coded month calendar in seconds. Unlike heavyweight cycle trackers, OvuWatch is a pure calendar-method ovulation calculator: no account, no community feed, no symptom questionnaires. And it gets smarter on its own — once you have logged two or more periods, predictions switch from the number you typed to the median of the real gaps between your logged cycles. WHAT YOU GET • Your estimated ovulation day and six-day fertile window on a colour-coded calendar, from just one date and one number • “Ovulation in 4d · next period in 18d” — a summary card that answers today’s question the moment the app opens • Predictions that sharpen themselves: after two logged periods the app uses the median of your real cycle gaps, not your guess • A reminder two days before your fertile window opens, so you plan ahead instead of finding out afterwards — plus ovulation-day and period-due alerts • A bar chart of every observed cycle length, with a plain warning when your cycles vary too much for calendar estimates to be trusted • Tap any logged cycle to edit or delete it — every prediction and reminder rebuilds instantly PERFECT FOR • Couples trying to conceive who want the fertile window on a calendar, not buried in a social feed • Anyone asking “when do I ovulate?” who has a period date and a cycle length — and nothing else to log • People with roughly regular cycles (21–35 days) who want a clean calendar-method estimate • Anyone who left a big-name tracker over data worries and wants predictions that never leave the phone WHY NOT JUST USE A BIG TRACKER APP? The famous trackers bundle accounts, content feeds, communities and data sharing around the one thing you came for. If what you need is the math — ovulation at cycle minus 14, fertile window from 5 days before through 1 day after — OvuWatch does exactly that, on a calendar you can read at a glance. PRIVATE BY DEFAULT Everything you enter stays in this app on this device. OvuWatch has no accounts, no servers, no analytics and no networking code — nothing you log is ever uploaded. Reminders are scheduled locally on your phone. IMPORTANT OvuWatch uses the calendar (rhythm) method. Predictions are estimates — your actual ovulation may differ, and the app tells you when your logged cycles are too irregular to rely on. It is not medical advice, and calendar estimates are NOT reliable for contraception: if you are avoiding pregnancy, use a proven contraception method and talk to a healthcare provider. PREMIUM (PURCHASE REQUIRED) OvuWatch requires Full Access, which unlocks the ovulation and fertile-window calendar, self-tuning predictions, cycle trend charts, and fertile-window, ovulation-day and period reminders. Choose an auto-renewing weekly or yearly subscription, or a one-time lifetime purchase. Type in your last period date now — your fertile window is on the calendar before you finish entering your cycle length.
