Ivy: Period & Cycle Tracker

Ivy is a private, easy period and cycle tracker. Mark your period days on the calendar and Ivy predicts your next period, ovulation and fertile window — so nothing catches you by surprise.

Your data stays on your phone. No account, no sign-up. Ivy never sees your cycle data, and it is never sold. Optional iCloud backup keeps everything safely in YOUR iCloud, so you can move to a new phone without losing a thing.

WHAT YOU CAN DO
• Tap the calendar to log period days — Ivy handles the rest
• See your next period, ovulation and fertile window at a glance
• Log symptoms, moods, sexual activity, water, weight and basal body temperature (BBT)
• Follow your current cycle phase right on the home screen
• Get gentle reminders before your period starts
• See trends and a full cycle history in Insights
• Export a report as PDF (to show your doctor) or CSV

PRIVATE BY DESIGN
• Everything is stored locally on your device
• No account and no cloud servers of ours — ever

Ivy is free, supported by ads — no subscription, ever.

Ivy is not a medical device and is not a method of contraception. Predictions are estimates and can be wrong; do not rely on them to prevent or achieve pregnancy. Talk to a healthcare professional about your health.
