MoonDial tracks menstrual cycles clearly, displays information concisely, and stores the data privately on your device.
Features:
* The progress 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 built-in guide (accessible by tapping the ? icon) shows app usage help.
* The color palette can be changed by tapping the palette icon (and there are more than a dozen options).
