High-intent answer

app that predicts energy and mood based on menstrual cycle phase

Cyca's Body Forecast gives you a daily estimate of energy, mood, skin, focus, social drive, and sleep quality based on where you are in your cycle — no wearable, no ML, just your own data.

Short answer

Each day, Cyca translates your current cycle phase and day number into a forecast across six wellbeing dimensions using phase-based patterns that are broadly consistent with published research on hormonal fluctuations: energy and mood tend to rise in the follicular phase as estrogen increases, peak around ovulation, then soften into the luteal phase as progesterone rises. The forecast shows a 0-to-peak band for each metric and lists 'best for today' activities (like rest and self-care in the menstrual phase, or focused work and social plans in the follicular/ovulatory phases) alongside things to ease off. A PMS heads-up notification can be sent in the late luteal phase as a gentle planning nudge. All calculations happen entirely on-device using your own logged cycle history — Cyca collects no population data and runs no cloud model. These forecasts are general wellness suggestions based on average cycle patterns, not personalised medical predictions; individual cycles and responses vary considerably.

FAQ

Is Cyca's Body Forecast scientifically validated?

The forecast uses general phase-associated patterns from menstrual cycle research — for example, rising estrogen in the follicular phase is broadly linked to improved mood and energy, while late luteal progesterone decline is associated with PMS symptoms. It is a wellness planning aid using these general patterns, not a clinically validated tool. Your experience may differ significantly from the general model.

What are the five cycle phases in Cyca?

Cyca tracks menstrual, follicular, fertile window, ovulation, and luteal phases. Each is displayed in a distinct colour on the cycle ring. Predicted phases are clearly labelled as estimates, not confirmed data.

Does Cyca send PMS reminders?

Yes. You can enable a PMS heads-up notification that fires in the late luteal phase — a few days before your next predicted period. This is a planning nudge, not a medical alert. Enable or disable it in Cyca's Settings.
