PeriodVol

Period volume & flow tracker

Free · In‑App Purchases

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.

Fixed: choosing a language in Settings didn't stick. If you picked Korean, the app went back to your phone's language the next time you opened it. Your choice is now remembered properly. Your entries stay on your device, as always.
