Fertility & Ovulation Days
Private Cycle & BBT Tracker
Free · Designed for iPad. Not verified for macOS.
Your body isn't a guessing game. Track your cycle privately, with honest predictions that sharpen over time — no account, no cloud, ever.
Fertility & Ovulation Days helps you understand your cycle — privately and honestly, with built-in guidance for couples trying to conceive together.
WHY THIS APP IS DIFFERENT
------------------------------
Most period and ovulation apps guess your fertile window from day one like it's a fact. We show you a confidence range that sharpens the more you log — because a 28-day cycle assumption isn't the same as knowing your body.
Everything stays on your device. No account, no cloud sync, no analytics, no ad trackers reading your cycle data. Ever.
FEATURES
-----------
- Fertile window & ovulation predictions that get more accurate over time
- Basal body temperature (BBT) charting with coverline ovulation confirmation
- Sync BBT and period history from Apple Health
- Visual calendar with color-coded chance-of-conceiving levels
- Cycle length trends and history, all in one place
- Gentle notifications for your fertile window, period, and pregnancy test timing
- Export a shareable PDF report for doctor visits
- Educational guidance for couples trying to conceive
- No account required — your data is yours
PRIVATE BY DESIGN
---------------------
We don't sell data because we don't collect any. No servers, no sign-up. What you log stays on your phone.
Whether you're trying to conceive, simply tracking your cycle, or supporting a partner through the process, Fertility & Ovulation Days gives you honest estimates instead of false precision.
