Bloom · Cycle & Fertility

Bloom is a smart, private period and fertility tracker designed for women who want accurate predictions without giving away their health data.

Unlike most trackers, Bloom stores everything on your device. No account. No cloud. No third parties. Your cycle is yours.

🌸 Period Tracking
Log your period start and end dates and Bloom learns your cycle over time. The more cycles you track, the more accurate your predictions become — using your own history, not a generic average.

🌿 Fertile Window & Ovulation
Bloom calculates your fertile window, peak fertility days, and estimated ovulation based on your personal cycle history. The calendar updates automatically as your data builds.

💜 OPK / LH Surge Tracking
Log your ovulation predictor kit (OPK) test results directly in the app. Positive OPK results are factored into your ovulation estimate for even greater accuracy.

🤍 Pregnancy Testing Guidance
Bloom tells you exactly when to take a pregnancy test — earliest possible (10 DPO with a sensitive test) and the reliable date (14 DPO) — so you're never testing too early and getting a false negative.

🧬 IVF & Embryo Transfer Support
Planning or going through IVF? Bloom includes a dedicated IVF mode that tracks your transfer date and calculates your implantation window, test dates, and key milestones based on your embryo day (Day 3 or Day 5).

📊 Cycle History & Trends
View your cycle length and period duration history over time. Bloom uses your averages to make smarter, more personalised predictions the longer you use it.

📋 Doctor-Ready Reports
Generate a PDF summary of your cycle history to bring to appointments. No screenshots, no explaining — just a clean report your doctor can actually use.

🔔 Smart Notifications
Get reminded when your fertile window is opening, when ovulation is approaching, when your period is due, and when it's the right time to test. Notifications work even when the app is closed.

🔒 Complete Privacy
Bloom was built with privacy as the foundation, not an afterthought. There is no account to create, no data sent to any server, and no analytics tracking your behaviour. Everything is stored locally on your device using your phone's secure storage.

This matters. Several major period tracking apps have faced investigations and controversies over how they handle sensitive reproductive health data. With Bloom, that concern simply doesn't exist.

Perfect for:
– Women tracking their natural cycle
– Anyone trying to conceive (TTC)
– Women using fertility awareness methods (FAM)
– Anyone going through IVF or fertility treatment
– Women who want period reminders without giving up their privacy

No subscription. No ads. No account. Pay once, use forever.
