Cycle Forecast & Planner
Plan ahead
of your cycle.
Not a tracker. Not a notification app.
Enter the first day of your last period and your average cycle length. DAYS forecasts your condition for the next 14 days and lines it up with your calendar, so you can see ahead of time when a sensitive stretch overlaps something important.
The 14-day forecast, overlap check and preparation tips are free

What Mocamoco DAYS does
A 14-day forecast in 30 seconds
Enter the first day of your last period and your average cycle length. Your day-by-day forecast for the next 14 days appears right away — no account, no daily logging.
Four-level condition forecast
See your phase (period, follicular, ovulation, luteal) and a gentle four-level read of the day: Upbeat / Steady / Sensitive / Rest-friendly.
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.
Preparation tips
Open an overlapping day for practical tips: what to get done early, how to keep the night before light, how to pace the day itself.
Look back
Mark each forecast "hit" or "miss" and see how well DAYS fits your rhythm over time.
Import from Health
Read your last period and cycle length from Apple Health "Cycle Tracking" or Health Connect on Android (read-only). Manual entry works just as well.

About Moca-chan
Moca-chan reads the day for you
Moca-chan is a little owl who feels at home in a coffee cup. Her expression changes with the day's forecast, and she adds a gentle hint on how to pace the day.
Upbeat
A day that tends to feel upbeat — room for an ambitious plan
Steady
A day for your usual pace
Sensitive
Mood and energy may fluctuate — leave some slack around plans
Rest-friendly
A day to go easy and make time to rest
Tendencies only — they vary from person to person
