CycleAI:Period Tracker

Free AI period tracker with real cycle science, a Life Planner that times your best days, and 24/7 AI chat. No paywall, ever.

CycleAI is the free period and cycle tracker built on real hormone science — not guesswork.

Track your period, ovulation, and fertile window with predictions that get sharper the more you log. Every day of your cycle is mapped, from the follicular rise to the luteal wind-down, so you always know what your body is doing and why.

WHAT MAKES CYCLEAI DIFFERENT

• AI Chat, 24/7 — Ask anything about your cycle, symptoms, or fertility and get real, judgment-free answers grounded in your own data. Not a chatbot script — an assistant that actually knows your cycle.

• Life Planner — Type any date, past or future, and see exactly how your cycle will shape it. Time job interviews, first dates, and presentations around your best days.

• Doctor-Ready Reports — Generate a clear PDF summary of your cycle history, symptoms, and patterns in one tap. Walk into your next appointment prepared, not guessing.

• Full Symptom Tracking — Log mood, energy, cramps, sleep, and more. Tap any date on your calendar to see exactly what your body was telling you.

• For Partners — Help the people who care about you understand your cycle too, without ever compromising your privacy.

PRIVATE. FREE. NO CATCH.

CycleAI is free forever — no paywall, no premium tier hiding the features that matter. Your health data stays private, always.

Whether you're trying to conceive, just trying to understand your own patterns, or tired of apps that oversimplify your body, CycleAI gives you the full picture — every symptom, every day, mapped.
