How it works
Six steps from install to a private, encrypted symptom history, and back again on a new device.
-
1. Sign in
Open CrohnOlogy and sign in with your Google account. Access is restricted to authorised family members only. If your email isn't on the family list, you can't get in.
-
2. Create or join a family
The first parent sets up the family and chooses a Family Recovery Passphrase (at least 8 characters), which is backed up securely as the recovery path. Everyone else joins by scanning the Admin's QR code. A secure handshake brings the new device into the family. No passwords to share.
-
3. Unlock with biometrics
Confirm with your face or fingerprint to unlock the encryption key. This happens once when you open the app; a short-lived session key then keeps things smooth for 120 seconds before you're asked again.
-
4. Log entries
From the Report screen, tap a large button to log Food, Stool, Pain, or Weight. Entries are encrypted on the device and uploaded instantly. Need to back-date something? Adjust the entry time to when it actually happened.
-
5. Review the timeline
The Journal shows a colour-coded timeline of everything the family has logged. Today's entries appear live; older history loads as you scroll. The analytics view summarises the last 14 days so you can spot patterns. Tap any entry to view, edit, or correct it.
-
6. Recover on a new phone
Lost or replaced your phone? Sign in on the new device and enter the Family Recovery Passphrase. CrohnOlogy securely recovers your key from the encrypted backup and restores full access to the family timeline.
