ABPM is gold standard but home logs are a mess. £0 PWA gives GPs structured 24h data without hardware change.

Problem

~14m UK adults have high blood pressure.

Ambulatory BP monitoring (ABPM) is gold standard, but NHS hardware is in short supply and home logs are scribbled paper. Cheap home monitors are everywhere; the data they produce is wasted.
