Ciclara: Period & Cycle

About this app

Ciclara connects your cycle to the rest of your body — your sleep, your resting heart rate, your energy — and explains what it finds in plain language. Nothing leaves your iPhone. AN INSIGHT ON DAY ONE Most trackers ask you to log for three months before they say anything. Ciclara reads the sleep and heart data already in Apple Health and shows you your first real pattern before you have logged a single day. PATTERNS, NOT HOROSCOPES • How your sleep changes across your four phases. • Which symptoms cluster where, and in how many of your recent cycles. • Resting heart rate and HRV against your own baseline, not a population average. • A weekly summary written on device, from your data. Every screen with a number on it tells you the formula behind it and cites its source. Ciclara reports patterns in what you logged — it does not diagnose, and it is not a medical device or a contraceptive. FOUR WAYS TO USE IT • Cycle — phases, predictions, symptoms and moods. • Fertility — an estimated fertile window and basal temperature charts. • Pregnancy — weeks, trimesters and a due date you can correct with a scan. • Perimenopause — cycle variability and the symptoms that come with it, without being told you are "staged". BUILT AROUND YOUR DAY • A home-screen widget and a Live Activity for the days before your period. • An Apple Watch app for logging without your phone. • Face ID lock on the whole app. • A one-page PDF for your doctor, with the method printed on it. • A partner view that shares what phase you are in and nothing clinical. PRIVATE BY DESIGN No account. No sign-in. No analytics SDK, no advertising SDK, and the tracking prompt is never shown, because there is nothing to track. Your logs live in your iPhone's own database, and Apple Health data is read and correlated on device — no cycle, no symptom and no health sample is ever uploaded. The one thing that leaves your phone is whether you own Ciclara Pro, checked against an anonymous purchase id that is tied to no identity. SELUNA PRO Logging, the calendar, your next-period prediction, the widget, the Watch app and the two strongest insights are free forever, as is every explanation of how a number was calculated. Pro adds the rest of the pattern analysis, the Apple Health correlations, the fertility, pregnancy and perimenopause modes, partner sharing and the doctor's report. Accessibility is never behind the paywall. Pro is available monthly, annually or as a one-time lifetime purchase. Prices, renewal terms and any free trial are shown in the app before you buy; subscriptions renew until cancelled in your Apple Account settings.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
