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 never leaves your device. Ever.

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.

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.
