FlowSense: Period Tracker

Track your period, predict your cycle, and understand your body — all privately, on your phone. No accounts, no cloud, no data leaves your device.

FlowSense is a beautifully simple, fully private period and cycle tracker designed for women who want clarity about their bodies without giving up their privacy.

Unlike most period apps, FlowSense never asks you to create an account, never sends your data to the cloud, and never shares your information with advertisers or third parties. Everything lives only on your phone — your cycle is yours alone.

— KEY FEATURES —

• Period Tracking — Log start and end dates, flow intensity, and notes for every cycle. • Smart Predictions — See your next period, fertile window, and ovulation day predicted from your own history. • Beautiful Calendar — A clean monthly view that shows your past and predicted cycles at a glance. • Symptoms & Mood — Track cramps, mood, energy, sleep, and any symptoms you care about. • Cycle Insights — Average cycle length, period length, and patterns over time. • Reminders — Gentle local notifications before your next period or fertile window. • 100% Private — No account. No login. No internet required. No analytics. No ads. Ever.

— WHY FLOWSENSE —

Most period apps treat your most personal data as a business asset. FlowSense doesn't. There is no server, no signup, no tracking pixel, no ad SDK. Your cycle data is stored locally on your iPhone and stays there. If you delete the app, your data is gone with it.

FlowSense is perfect for anyone who wants: • A clean, calm interface without ads or social feeds • Honest cycle predictions based on their own data • Total control of their reproductive health information • An app that respects them as a person, not a data point

— IMPORTANT —

FlowSense is a wellness and tracking tool. It is not a medical device, and it is not a substitute for advice, diagnosis, or treatment from a qualified healthcare professional. Do not use FlowSense as a method of contraception. Predictions are estimates based on the data you log and may not be accurate, especially for irregular cycles or new users. Always consult your doctor about any medical concerns.
