Ovelle: Period Tracker & Cycle

The private period tracker: no ads, no data sold, no subscription. Track your period, ovulation, fertile window and pregnancy free, with smart predictions.

Ovelle is a private period tracker and ovulation calendar with no ads, no data sold and no subscription. Track your menstrual cycle, fertile window, ovulation and pregnancy in one calm, uncluttered app.

TRACK WHAT MATTERS • Log your period, flow, spotting, symptoms, cramps, mood, and notes in seconds • See predictions for your next period, fertile window, and ovulation • Switch between cycle tracking, trying to conceive (TTC), and pregnancy modes as your life changes • A week-by-week pregnancy dashboard with due date and baby size

UNDERSTAND YOUR PATTERNS Ovelle's "Noticed for you" insights are computed entirely from your own logged data: cycle regularity, trends, and PMS symptom or mood patterns. Nothing is sent anywhere to generate them.

PRIVATE BY DESIGN • No ads. No ad trackers. No data sold, ever. • Your logs sync to your own account, locked to you by security rules • Delete your account and every trace of your data anytime, right in the app • Free: no subscription, no paywalled features

GENTLE REMINDERS A local notification reminds you 2 days before your period is due. No server involved, just a quiet nudge when you need it.

Whether you're tracking your cycle, trying to get pregnant, or expecting, Ovelle keeps it simple, honest, and yours.

Ovelle is not a form of birth control and does not provide medical advice.
