Daikon: Period Tracker

A little care, every day. Daikon is a simple, joyful period tracker and a diary that knows your cycle. Log your period, see what may be coming next, and let a few little white radishes brighten your day. When your period arrives, they turn into red carrots. On estimated ovulation day, one wears a flower. YOUR RHYTHM AT A GLANCE A colorful cycle ring shows period days, the estimated fertile window, ovulation, and today. See the next three predicted periods and upcoming fertility dates. ONE LITTLE LOG Tap “My period started” or “My period ended.” The babies jump, spin, and shower you with leaves. Edit past days in the calendar; neighboring days join automatically. A DIARY THAT KNOWS YOUR CYCLE Every day gets a page: your mood, how you feel, a few words, handwriting with Apple Pencil or your finger, up to nine photos and voice memos. See a month of moods and photos, search every page, look back on the same day in past years, and export your diary as a PDF. PATTERNS AND RECAPS Mark how you feel for a few cycles and Daikon shows what keeps coming back, like cramps two days before your period. A recap sums up your last cycle; on devices with Apple Intelligence, it can be written for you on the device. YOUR HISTORY How regular your cycles are, where the next one could start, every past cycle and a PDF for your doctor. Undo a log, pause predictions, or bring in past logs from a CSV file or Apple Health. WIDGETS, SIRI AND LOCK Home Screen and Lock Screen widgets, a Control Center button, Siri, and the period day on your Lock Screen. Lock Daikon with Face ID, Touch ID or your passcode. PREDICTIONS THAT KEEP GOING Daikon learns from up to six recent cycles, or uses a cycle length you choose. If you haven’t logged a new period, estimates keep rolling forward. A gentle prompt helps you update your history. GENTLE, OPTIONAL REMINDERS Choose a period reminder, an estimated fertile-window reminder, or a “Did your period start?” check-in. All are off until you turn them on. Reminders are local notifications. APPLE HEALTH, IF YOU WANT IT Turn on “Sync to Apple Health” in Settings to save each logged period day as menstrual flow in the Health app. It’s off by default and keeps your Health data if you turn it off. “Delete all logs” also removes what Daikon wrote there. While iCloud is off for Daikon, you can also import past periods from Health. PRIVATE LITTLE GARDEN No account, community, or subscription. Your logs and diary, photos and voice memos included, are stored on your device and can sync through your private iCloud when available. Handwriting and recaps are recognized and written on your device. Your health data is never sent to the advertising SDK or used to target ads. If you turn on Apple Health sync, period days are also saved in Health. On an unfolded iPhone Duo, a 13-inch iPad in portrait or any iPad in landscape, today and the calendar sit side by side. Designed for iPhone and iPad, in English, Traditional Chinese, Simplified Chinese, Japanese, Korean, Spanish, French, and German, with a warm light and dark appearance and support for Reduce Motion. Advertising: non-personalized interstitial ads may appear after logging and its animation finish, at most once every four minutes. Your first session is ad-free. Ads never block logging. A one-time “Remove ads” purchase in Settings turns ads off for good, with “Restore purchases” on your other devices. Predictions are estimates, not medical advice or contraception. Cycle timing can vary. Support: https://easonwumac.github.io/daikon/support.html Privacy: https://easonwumac.github.io/daikon/privacy.html
