A Clue alternative with no account
Clue needs an account and keeps your data on its servers. Iris needs no account and keeps your cycle on your iPhone, with every feature free.

What Iris covers
- Period predictions from your own cycles
- A likely window for irregular cycles and PCOS
- BBT chart with a coverline, and LH test logging
- Partner sharing with a private code, end-to-end encrypted
- Two-way Apple Health sync, widgets and reminders
- A PDF report for your doctor
When Clue is the better fit
Clue runs on Android as well as iPhone, and an account means your data follows you to any device. Iris is iPhone and iPad only, and moves between your own devices through your iCloud instead.
Questions
Why does no account matter?
Without an account, nothing links what you log to your name or email, and there is no copy of your cycle on a company server.
Can I bring my history?
If your periods are in Apple Health, Iris reads them in. Otherwise add your last few period dates on the calendar.
Iris is not a contraceptive. Its predictions are estimates, and it never marks a day as safe.
