## What is Cycle & Period Tracker · Onda?

Onda is a private period tracker and ovulation calendar that learns your cycle. No account, no cloud, no ads: everything you log stays on your iPhone.

HONEST PREDICTIONS
• Your next period with an honest range ("likely Oct 3–5") that narrows as you log
• Estimated fertile window and ovulation, personalized from your own cycles
• Positive LH tests and a basal temperature shift update the estimate
• Apple Watch temperature: nightly wrist temperature from Apple Health helps confirm ovulation (Apple Watch Series 8 or later or Ultra, with Health sync on)
• A clear heads-up when your period is late, and when a cycle is worth discussing with a doctor

LOG IN ONE TAP
• Flow and spotting, 20+ symptoms, moods, discharge, sex drive, LH and pregnancy tests, temperature, weight, pills, your own tags and notes
• "Period started" fills in your usual length; edit any day in the calendar
• Siri and Shortcuts: "My period started in Onda", "When is my next period in Onda"

UNDERSTAND YOUR CYCLE
• Cycle history and a typical-or-atypical check against medical reference ranges (FIGO)
• Pro: your patterns, such as which symptoms and moods come when (bloating two days before your period, for example)
• Pro: Coming up — the symptoms your own patterns expect in the next few days, with an optional heads-up the evening before
• Pro: temperature and LH charts that show when ovulation likely happened
• Pro: a clean PDF report to bring to your doctor

FOR EVERY STAGE
• Track your cycle, try to conceive, follow a pregnancy week by week, or navigate perimenopause
• On a hormonal method? Onda hides fertile-day estimates while you use it
• Reminders for your period, fertile window, daily log, morning temperature and your pill
• Pill packs: 21+7, 24+4 or 28 days; reminders skip break days, and you can mark "Taken" right from the notification

PRIVATE BY DESIGN
• No account, no cloud, no ads, no trackers. App Privacy: Data Not Collected
• Face ID lock, plus discreet notifications and widgets
• Optional Apple Health sync and import; export your own backup file any time
• Password-protected backups: an encrypted file that only you keep
• Share dates, not data: send your partner a message or a calendar file with your predicted periods
• Ask about your cycle: a private assistant that runs on your iPhone (needs Apple Intelligence and iOS 26 or later; 3 questions included, unlimited with Pro)

WIDGETS
• Home Screen and Lock Screen widgets with your countdown, cycle day and fertile window
• A "Period started" button on the Home Screen widget when your period is due

ONDA PRO
Pro adds patterns and symptom forecasts, temperature and LH charts, the doctor report and unlimited assistant questions. Logging, predictions, the calendar, every mode, reminders, widgets, Apple Health and backups stay free. Pro is available as a yearly subscription with a free trial, a monthly subscription, or a one-time lifetime purchase. Payment is charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel them in your Apple Account settings.

Onda is not a medical device and not a method of contraception. Predictions are estimates, not medical advice.
