MoonDial tracks menstrual cycles clearly, displays information simply, and stores the data privately on your device.
- The dial shows the current cycle and the estimated number of days until the next period start.
- The calendar shows past cycles, future predicted periods, and estimated ovulation ranges.
- The history chart shows start dates and cycle lengths, and handles adding or updating entries.
- The period-countdown badge on the MoonDial icon (enabled in device system settings) shows at-a-glance information without opening the app.
- The guide (accessible by tapping ?) shows app usage help.
- The color palette can be changed by tapping (and there are more than a dozen options).
