About this app
Cykel is a private period, ovulation, and fertility tracker that keeps your health data where it belongs — on your phone. 🌸
No account. No sign-up. No ads. No cloud. Your menstrual data never leaves your device.
🌙 TRACK YOUR CYCLE
• Period tracking — log start and end dates in one tap
• Cycle predictions — next period, ovulation, and fertile window, estimated from your own history
• Symptom tracker — 19 symptoms, from cramps, bloating, and acne to fatigue, PMS, and brain fog
• Daily check-in — log your whole day in one tap, with a little celebration when you're done 🎉
• Menstrual calendar — color-coded month view of your full cycle history
• Insights — cycle length trends, period stats, and frequent symptoms across 3, 6, or 12 months
📔 DAILY LOG & WELLNESS
• Mood tracker — log how you feel and see patterns across your cycle
• Wellness log — water, sleep, and weight, all in one daily view
• Activity & movement — cycle-synced yoga and workout routines
• Private notes — a journal for anything about your day
🤍 ALSO HELPS WITH
• Irregular periods and PCOS — turn on PCOS mode to spot patterns across months. PCOS has a new name — PMOS (polyendocrine metabolic ovarian syndrome) — and whether your doctor says PCOS, PMOS, or PCOD, Cykel has you covered
• Late or missed period — see your full history at a glance
• PMS and mood tracking — log symptoms in the days before your period
• Fertility awareness — track basal body temperature (BBT), LH tests, and cervical mucus
• Trying to conceive or to avoid — understand your fertile window, with an optional conception-chance view
📚 LEARN & MOVE
Phase-synced yoga and movement routines, plus simple tips on what to eat and how to feel your best through every phase of your cycle.
🔒 PRIVATE BY DESIGN
• Your data is stored in an encrypted database on your device
• App lock — protect Cykel with a PIN, fingerprint, or face
• Screenshot blocking for extra discretion
• No third party ever sees your health data
• The only thing that ever leaves your phone is an anonymous crash report if the app crashes — it contains no health information
✈️ WORKS COMPLETELY OFFLINE
Tracking, predictions, insights, and the built-in assistant all work without internet. There is no server. Airplane mode? Everything still works.
🧠 ASK CYKEL
A private, offline assistant that answers questions like "When is my next period?" or "What are my most common symptoms?" — using only the data on your phone.
🔔 GENTLE REMINDERS
Upcoming period, late period, fertile window, daily check-in, plus your own medication or supplement reminders — all yours to customize.
🏠 HOME SCREEN WIDGET
Your cycle day and next period, right on your home screen.
💛 YOUR DATA IS YOURS
• Export your logged data anytime
• Encrypted backup and restore with a passphrase you choose
• Delete everything with one tap — gone means gone
🌍 SPEAKS YOUR LANGUAGE
English, Spanish, French, Hindi, Indonesian, Portuguese, Thai, and Vietnamese.
NO ACCOUNT NEEDED
Open the app and start tracking immediately — no email, no password, no personal questions.

Anyone who wants a simple, beautiful period and ovulation tracker without giving their menstrual data to a company.
