What it does
Honest estimates, every insight included
Tap “Period started” and CommuniHer does the rest: today’s cycle day and phase on a simple ring, a month calendar, and an estimate of your next period drawn from your own history. When it doesn’t have enough data yet, it says “still learning” instead of inventing a date.
One‑tap logging
Start and end your period with one tap, then add flow, symptoms, mood, energy, sleep and notes with big, easy chips.
Honest predictions
Your next period as a date with a ± range and a confidence level, plus how far off past predictions were.
Every insight included
Cycle and period length history, variability, and which symptoms cluster in which phase. Nothing is held back.
Basal temperature
A temperature chart that marks a sustained rise, plus pill, patch, ring and other medication reminders on their own schedules.
Works with Apple Health
Optional: save period days and temperatures to the Health app, and bring in periods logged by other apps or Apple Watch.
A report for your doctor
A PDF of your averages, cycle history, symptoms by phase and temperatures, ready to share at an appointment.
A look inside
From today’s ring to a year of history
Everything you see here is in the app everyone gets.
A wellness tracker, not a medical device
CommuniHer does not diagnose, treat or screen for any condition, does not confirm or rule out pregnancy, and is not a method of contraception. Fertile-window estimates and temperature observations are for planning only and can be off by days. If anything about your cycle concerns you, talk to a healthcare provider.
Track your cycle, calmly
Every feature is included. After the first free day, one short ad opens the app for the next 12 hours. That’s the whole business model.
Free, no subscription.
