Fertility Tracker: BBT & IVF

Fertility Tracker is an all-in-one journal for your fertility journey — from timing and TTC to IVF treatment. Record everything that matters in one private, secure place.

⚠️ Note: The app interface is currently available in Japanese only. An English version is planned.

🔒 Privacy first
• Health records (basal body temperature, cycles, medications, visits, treatment stages, receipt photos) are stored with end-to-end encryption — our servers cannot read your data.
• Receipt text is extracted on your device (on-device OCR); images and text are never sent to any external recognition service.

✨ Features
• Basal body temperature (BBT) chart
• Period & cycle tracking
• Medication reminders
• Clinic visit schedules with day-before reminders
• Treatment stage management (egg retrieval, transfer, rest)
• Cost tracking for medical expense records, with receipt photos
• Partner sharing — share what you choose, with gentle reactions
• AI-powered support for your questions

💛 Free & Premium
Core tracking is free. Premium unlocks advanced AI support and more storage.

Take care of yourself, one record at a time.
