Wake up to a caring daily reading of your energy, mood, skin, and comfort, based on where you are in your cycle — with kind suggestions to plan your day with ease.

Smart, personal predictions
Cyca learns your unique rhythm to predict your next period, fertile window, and ovulation, and adapts every time you log.

A calendar that feels calm
See your whole cycle at a glance — period days, fertile window, and ovulation in soft, clear color. No clutter, just clarity.

Log in seconds
Record flow, symptoms, moods, and notes effortlessly, and watch your personal patterns gently appear over time.

Insights that care
Personal Rhythm shows how your body tends to move through each phase. The Smart Planner highlights your best and gentlest days, so you can plan life around how you actually feel.

Gentle care, never clinical
A daily Care Plan and a kind heads-up before your period or PMS help you be a little softer with yourself — supportive guidance, never cold or clinical.

Private by design
Your cycle is yours alone. Cyca has no servers and no account — your data never leaves your device, and the app works fully offline. Privacy isn't a setting here; it's the whole design.

One-time unlock, no subscription
Track today and your period for free. Unlock Cyca Pro once for future predictions, Personal Rhythm, the Smart Planner, full calendar history, and deeper personalization — a single one-time purchase, never a subscription.
