Cycluna is a period and cycle tracker that keeps everything on your iPhone. No account. No sign-up. No data leaving your device, because there is nowhere for it to go. Know where you are Your cycle day, your phase, your fertile window, and when your next period is likely to arrive. One look and you know. A calendar that knows your rhythm Period days and fertile days marked across the month, so planning ahead doesn't take math. What your body is actually doing Each phase explained in plain language, with a hormone reference chart showing how oestrogen, progesterone, LH and FSH move through a typical cycle. A journal that's actually private Moods, headaches, and anything you want to write down. Lock it behind Face ID if you like. Patterns, only when they're real Cycluna looks at your mood and headache logs across your days, your cycle phases, and the lunar month. It only names a pattern when there is enough data to support one — and says so plainly when there isn't. No invented insights. The moon, every night Tonight's moon phase, the nights ahead, and how your own logs sit across the lunar month. Research has not established a moon–mood link, and Cycluna does not pretend otherwise — this lens describes your logs and nothing more. Reminders before it matters A gentle nudge before your period or ovulation, scheduled by your own phone. Turn them off and they're gone. Yours to take with you Export your data whenever you want. Delete it and it's gone from the device for good — there is no copy anywhere else, because we never had one.
