Calla.
Coming to the App Store

Track perimenopause. Keep it on your phone.

Calla records symptoms, hot flashes and HRT, then turns months of them into one page your doctor can read in a minute. No account, no server, nothing to sell.

Logging that takes seconds

A hot flash is one tap from the Home Screen. The rest of the day is a short list, not a questionnaire.

A report for your appointment

Symptom load, cycle history and treatment on one PDF – generated on your iPhone, yours to share or delete.

Private by construction

Your entries live in an app-private database on the device. There is no sign-up, because there is nowhere to sign up to.

Built for the whole transition

Perimenopause rarely arrives on a schedule, and plenty of women reach it without a cycle to track – after a hysterectomy, with an IUD, on contraception, or years past the last period. Calla never asks you to log a period to keep going.

What it shows are observations from your own entries, with the number of days behind each one. It does not diagnose, and it will never suggest a dose. Those conversations belong with your clinician – Calla just makes sure you walk in with the data.

Not out yet. Calla is in testing on iPhone. If you would like a note when it ships, or you want to help test it, write to support@callatracker.app – one email, nothing else.
