Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The period tracker that can't leak your data. 100% offline, no account, no cloud. PDF reports for your doctor. Your data never leaves your iPhone.
Verity Cycle is a 100% offline period & cycle tracker. Your data stays on your iPhone — no account, no cloud, no ads, no analytics. Track menstruation, BBT, ovulation, 40+ symptoms, and mood. Export doctor-ready PDFs. Available in 5 languages.
WHY VERITY CYCLE
Other period trackers ask for your email, sync to their cloud, and serve ads based on your cycle. Verity Cycle does none of that. Everything lives on your iPhone, encrypted by iOS, backed up only when you choose.
