Lumie.

Lumie helps you understand your cycle as a rhythm. Period dates, mood, energy, and body symptoms stay together, so you can see what tends to repeat and when your next period is likely to begin. Open the app and see where today sits in your cycle. Start a period, edit one you already logged, or look ahead to the next phase. Check in with mood, energy, flow, and symptoms, and keep a short journal for that day. The calendar shows both a month and a day-by-day timeline. Insights bring together cycle length, symptoms by cycle day, how often a signal appears, and the shape of your mood and energy. You can browse past cycles and search your notes. Period and daily check-in reminders can be set for a time you choose. A starting balance is included. Period logging, daily check-in, and journal text are part of Lumie. Cycle estimates are drawn from your own records. They are not a diagnosis and do not predict pregnancy.
