A private period tracker that learns your rhythm instead of assuming a textbook 28 days.
01 — Today
The home screen shows exactly where you are — current cycle day, expected window, and how regular your rhythm has been. One tap to log your period, one tap to record today's symptoms.
02 — Calendar
A full calendar view where period days are marked in rose. Tap any month to jump back — all the way to 2017 if you imported history. Edit periods by tapping days directly, just like selecting dates in any calendar app.
03 — Insights
See your cycle history at a glance — typical length, regularity drift, average phase lengths, and patterns over time. Understand how your cycle changed before and after starting a medication.
04 — Medications
Add your medications with doses, colors, start/stop dates, and daily reminders. See taken/missed dots right on the calendar. Dotti correlates medication changes with cycle pattern shifts in Insights.
05 — Labs
Record testosterone, fasting insulin, HbA1c, LH/FSH, AMH, and more. Watch values trend against typical ranges. See whether your numbers are moving in the right direction across appointments.
No ads. No analytics. No trackers. No data sold or shared — not with anyone, not ever. Your history lives in your own account, encrypted in transit and at rest, readable only by you when you sign in.
No analytics, no advertising SDKs, no third-party code that phones home. What you track stays between you and your account.
Your history is encrypted in transit and at rest, readable only by your signed-in account. You can delete everything permanently from Settings at any time.
We chose the design where you can sign in anywhere and recover your account — not the one where a forgotten password destroys your history. The full reasoning is in the privacy policy.
Free. Private. Built for your cycle, whatever it does.
