Cykie

A period tracker that feels more like a notebook than a medical chart.

Log a day in two taps, see when your next period and fertile days are due, and dress the whole app up the way you like. Everything you log stays on your phone.

What's inside.

Predictions that learn

Your next period and fertile window, based on your own cycles, with a heads up on how much it could move.

Period, fertile and ovulation days at a glance, plus up to four stickers on any day.

Fertility tools

A temperature chart that spots the rise after ovulation, LH and pregnancy tests, and cervical mucus.

Symptoms and moods

Log flow, pain, sleep, cravings and more, then see what tends to come back each cycle.

Make it yours

Five looks, a character you design yourself, 160+ stickers and home screen widgets.

A report for your doctor

A tidy summary of your recent cycles you can share or print before an appointment.

Privacy
