About this app

A condition forecast planner built on your menstrual cycle.

Mocamoco DAYS forecasts your day-to-day condition tendencies from your cycle and checks them against the events already in your device calendar — so you can see, ahead of time, when a sensitive stretch overlaps something important. Not a tracker, not a notification app: DAYS is for planning ahead.

FOR YOU IF…
• You worry whether you'll feel like yourself on days that matter
• You'd like to schedule work, trips and plans around your rhythm
• You don't want to log anything — just enter once and read the forecast

WHAT IT DOES
◎ A 14-day forecast in 30 seconds
Enter the first day of your last period and your average cycle length (or import from Health Connect). Your 14-day, day-by-day forecast appears right away.
◎ Four-level condition forecast
See your phase (period, follicular, ovulation, luteal) and a gentle four-level read of the day: Good / Normal / Sensitive / Rest.
◎ Calendar overlap check
DAYS reads your device calendar (read-only — it never creates or edits events) and marks events that fall on sensitive days with a warning icon. Open a day for preparation tips: what to do the day before, how to pace the day itself.
◎ Look back
Mark each forecast "hit" or "miss" and see how well DAYS fits your rhythm.
◎ English and Japanese

DAYS PREMIUM (auto-renewable subscription)

PRIVACY
No sign-up needed. Health data you enter or import — your cycle included — is stored only on your device and is never sent anywhere. Health and Calendar access can be revoked at any time, and "Delete all data" is one tap away in Settings.

PLEASE NOTE
Forecasts and tips are general information to support your planning. They are not medical advice, diagnosis or treatment. Condition tendencies vary from person to person; consult a doctor or specialist about any symptoms that concern you.
