My Cancer eDiary

A private, personal cycle calendar and symptom diary for tracking cancer treatment — built for patients and the family helping them through it.

What it does

My Cancer eDiary keeps chemotherapy cycles, appointments, symptoms, and day-to-day notes in one place, on your device.

Built for family, not just yourself

Turn on Share with Family and invite the people helping with your care — they'll see the same up-to-date information you do, kept in sync automatically through your own private iCloud account via Apple CloudKit. No separate account, no third-party server.

Your data stays yours

Everything is stored on your device by default. Nothing is sent anywhere unless you choose to turn on family sharing, and even then it only goes to your own iCloud account and the people you specifically invite. No ads, no analytics, no tracking.
