A local-first pain diary — register pain symptoms as they happen and present them concisely to your doctor.
Log each pain episode in seconds: body location, intensity on a 0–10 scale, what the pain feels like (burning, stabbing, dull, throbbing, …) and an optional note. Browse your history grouped by day, then open the report view for a per-location summary of frequency, average and worst intensity — made to be read by a doctor in under a minute. Everything is stored in your browser; nothing ever leaves your device. Install it from your browser menu and it works offline like a native app.
