Period Tracking
Log your periods in one tap from the calendar or the editor. Duration, interval and year are validated at input so your history stays medically meaningful.
Your cycle, clearly tracked.
Log periods, predict ovulation and the fertile window, follow your contraceptive pill pack, and keep medical visits on track - quietly, in 14 languages. No account required, your data never leaves your device.
Everything your cycle needs
A clean, no-pressure companion built for your body
Cycle Ring & Predictions
A circular ring shows the current day of your cycle and the upcoming phase. Up to 13 cycles are predicted ahead using the median of your recent history.
Fertility & Ovulation
Optional fertile window and ovulation estimates based on your luteal phase. Computed strictly for information - never as contraception.
Contraceptive Pill
Track 21/7, 24/4 or 28-day packs on a timeline. Confirm daily intake, see missed days at a glance, and get a daily reminder at the time you choose.
Appointments
Record past visits and upcoming appointments with custom reasons, per-doctor reminders, and one-tap call / SMS / email from each card.
Smart Reminders
Period start, period end confirmation, pill intake, pack end, doctor visits and birthday. Explicit or discreet wording - your choice, per reminder.
Statistics
Median cycle length, median period length, and variability across your last cycles. The app never lets a single atypical cycle skew the estimate.
Widgets
Home-screen widgets for cycle countdown and the current pill pack. Two sizes, automatically in your chosen language.
iCloud Sync
Your profile, periods, packs and visits sync across your iPhone and iPad via your personal iCloud. On-device first, always.
14 Languages + RTL

No account. Your cycle, period, pill and medical data never leaves your device or your own iCloud — never shared with advertisers. Full GDPR + ATT controls. Export as JSON and wipe in one tap.
Accessibility Built-in
