Period Tracker Pro - Ovulation

Period Tracker Pro logs your periods and estimates your next period, ovulation and fertile window. Tap "Period started" once, then record flow, symptoms, mood, basal body temperature and pills in a few taps. No account needed: your records stay on this device.

KEY FEATURES

• One-tap period logging
Tap "Period started" and period days are filled in as each day arrives, up to your usual length, until you tap "Period ended". Missed a day? Pick "Started on another day". In the calendar, "Edit period days" fixes past months.

• Log your whole day
Flow (4 levels), spotting, 17 symptoms, 10 moods, discharge, sex, BBT, weight, ovulation and pregnancy tests, pills, notes and your own tags. Hide what you don't use. Every tap saves at once.

• Period and ovulation predictions
Your next period comes from the average of recent cycles, with a ± range from their variation. Ovulation is estimated 14 days before the next period (luteal length is adjustable); the fertile window runs from 5 days before to the day after. A positive ovulation test moves this cycle's ovulation. If it's late you see "N days late".

• Predictions that fit you
Average 3, 6, 12 or all cycles, fix the cycle length or set the luteal length. Cycles under 15 or over 90 days are skipped, and you can exclude any cycle. Hide ovulation and fertile days or turn predictions off. Choose "Trying to conceive" to see your chance of conception on Home.

• Home, calendar and insights
A cycle ring shows your period, fertile window, ovulation and today, with days until your next period and what's next. The month calendar marks logged and predicted periods, fertile days and ovulation. Insights show averages, variation, charts, cycle history and your most logged symptoms.

• Reminders
Before your period and on the day, when late, fertile window, ovulation, daily log and BBT time. "Hide what notifications are about" keeps the word "period" out of notifications and widgets. "Notification check" shows the next reminder and what may block it.

• Pregnancy mode
See weeks pregnant and your due date on Home. Period predictions and reminders pause; logging goes on.

• Lock and privacy screen
Lock with fingerprint, face or device PIN, hide it in recent apps and block screenshots.

• Backup for new phones
Export a backup and restore it on a new phone. Daily auto backup to a folder you choose, undo for the last restore, and CSV export and import for Excel or Google Sheets.

• Widgets, tile and sharing
"Next period" and "Today's log" widgets (log your period without opening the app), a Quick Settings tile, and sharing your next period as text or a calendar event.

PREMIUM (ONE-TIME PURCHASE)
