Cycle Tracker: Period Log
Private Ovulation & Fertility
Free · Designed for iPad. Not verified for macOS.
Built by a gynaecologist, not an ad network. Your cycle data never leaves your phone — no account, no cloud, no tracking.

Cycle Tracker was developed with the clinical care your reproductive health deserves. Whether you are monitoring your cycle, planning a pregnancy, or simply learning your body's patterns — this app gives you the tools to do it right.
IMPORTANT
Cycle Tracker is a tracking and educational tool, not a medical device. Predictions are statistical estimates calculated from the cycle history you enter — they are not a diagnosis and must not be used as a method of contraception or to rule out pregnancy. Always speak to your doctor before making any medical decision.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Pregnancy tests and cycles left out of your averages.
Also in this release:
• Log pregnancy tests. After a positive test, period and fertility predictions pause, and that cycle stays out of your averages; bleeding early in a pregnancy, or after a loss, is not counted as a period
• In History, "Count in averages and predictions" leaves out a cycle affected by treatment, hormones or another reason
• A positive LH test dates your next period from your own ovulation, and your own luteal phase is used once LH tests have measured it
• The file for your clinic carries pregnancy tests and left-out cycles
• History flags a period that has lasted more than 8 days while it is still going on
The app does not access the network: your data stays on your device.
