Wren — Period & Cycle Tracker

Wren is a clean, private period and cycle tracker for anyone who wants to understand their body — without forced ads, without selling your data, and without constant upsell interruptions. Your data stays on your device. Backups are optional, encrypted with your own passphrase, and go only where you choose to save them. WHAT WREN DOES - Predicts your next period, fertile window, and ovulation based on your logged cycles - Shows your current cycle phase every day — menstrual, follicular, ovulatory, or luteal - Gives you a motivational daily card based on where you are in your cycle - Lets you log flow, symptoms, mood, and pain intensity each day - Tracks patterns over time so you actually understand what's happening JOURNAL Write freely. Log how you feel, what's happening, what you notice. Your journal stays private on your device. STATS See your cycle averages, symptom patterns, and mood trends at a glance. No jargon — just your data, clearly presented. PDF EXPORT (PRO) Export your full cycle history as a clean PDF. Keep it for your records, share it with your doctor, or anyone you choose. Your record, your way. ENCRYPTED BACKUP (PRO) Save an encrypted backup file protected by your own passphrase, then restore it anytime — on this device or a new one. The backup is locked to your passphrase, so only you can open it. Nothing is ever uploaded without your say-so. PIN LOCK Protect your cycle data with a custom PIN. Your information stays private even if someone else picks up your phone. NO INTRUSIVE ADS Wren never forces ads on you — no banners, no pop-ups, no interruptions. The only ad in Wren is one you can choose to watch to unlock a Pro day for free. Watch it or don't — it's always your call. WREN PRO A subscription unlocks everything: advanced stats, unlimited journal entries, PDF export, encrypted backup, and multiple profiles. Want a taste first? Watch a short ad for a 24-hour Pro pass — stats, journal, and export, free for the day. Wren is a personal tracking app, not a medical device. Predictions are estimates based on your logged data. Your cycle. Your rhythm.
