Your entries sync through your own iCloud. Nobody else can read them.

- Private — your own iCloud
- No ads, no data selling
- Under a minute to log an attack
What it does
Four things, done properly
Everything below is in the free version except the pressure forecast and the deeper correlations.
Logging
Finishable during an attack
A dial for severity, a tap for where it hurts, and you’re done. Symptoms, triggers, sleep, stress and medication are all there when you want them, and all optional when you don’t. Log now, add detail tomorrow.

Weather
Pressure recorded for you
The barometric-pressure change over the preceding 24 hours is captured the moment you log, because it’s the one variable nobody can reconstruct afterwards. You also get a plain forecast of the days ahead.

Patterns
Correlations, once there’s enough to say
How severity shifts on days with each trigger, and how your attacks line up against falling pressure. Nothing appears until there are enough entries to mean anything, and it’s described as a pattern in your data rather than a cause.

Appointments
A report built for the ten minutes you get
Attack counts, average severity, severity over time, and a clean PDF of your last 30 days. MIDAS and HIT-6 are built in, so you arrive with a disability score rather than an impression.

Privacy
Your data stays yours
Entries sync through your own private iCloud, not a server I control. I can’t read them, which also means I can’t sell them or lose them. Analytics are anonymous product-usage signals only and never carry health data. Everything exports as JSON whenever you want it.
