Track your disease activity.
Understand your flares.
A privacy-first iOS app for people living with Crohn's disease, ankylosing spondylitis, and other chronic inflammatory conditions.
Features
Flare Journal uses the same validated scoring instruments your specialists rely on — so your self-tracking data means something in the consulting room.
17 validated scores across 14 conditions — CDAI, HBI, BASDAI, DAS28-CRP, RAPID3, and more. The same instruments your specialists use, computed from your daily logs.
Visualise your disease activity over weeks and months with severity-zone charts. See patterns, track treatment response, spot flares early.
Zero servers. Zero accounts. Zero tracking. All data stays on your device and your personal iCloud. The developer cannot access your data.

Your data is yours. Always.
Health data is among the most sensitive personal information
that exists. Flare Journal is built on a simple principle:
the developer has no access to your data.
There are no user accounts, no analytics SDKs, and no data
ever leaves your devices. Everything lives in your personal
iCloud — encrypted, private, and under your control.
