PeriodVol

PeriodVol is a period tracker that measures what most apps ignore: how much you actually bleed. Instead of only logging dates, PeriodVol estimates your flow in millilitres — each day and across your whole cycle — so you can finally see your real numbers. It even flags when a cycle passes 80 ml, the clinical marker for heavy menstrual bleeding (HMB), so you can talk to a doctor with facts instead of guesses. LOG WITH PICTURES, NOT NUMBERS No math, no guessing. Tap the picture that matches what you used — a pad (by size and how soaked it is), a tampon, or a menstrual cup (by capacity and fill) — and PeriodVol turns it into millilitres for you. Clots and flow colour, too. KNOW WHAT'S NORMAL A clean cylinder shows your cycle total at a glance, with the 80 ml heavy threshold marked. Compare cycles over time with simple volume bars. PREDICTIONS Log a few cycles and PeriodVol predicts your next period, ovulation, and fertile window, right on the calendar. (Estimates only — not a method of contraception.) PRIVATE BY DESIGN • No account. No sign-up. • No servers — your data never leaves your device. • No ads, no trackers, and we never sell or share anything. • Optional PIN or Face ID / fingerprint lock. • Export a backup or delete everything anytime. Built for anyone who wants to understand their flow, watch for heavy bleeding, or simply track periods without handing their health data to a company. PeriodVol is not a medical device. Volume figures are estimates based on product-absorption research. Predicted dates may be inaccurate. Consult a healthcare professional for medical advice.
