Kōji Health

Kōji runs eleven clinics whose patients skew older than the average health app assumes. Type size, contrast and touch targets were requirements in the kickoff document, not findings in a report.

The system ships at AA or better everywhere, with a large-type mode that reflows rather than scales, and flows that survive a screen reader without a special path.

The identity had to work at 12 pt on a prescription label and at four metres on a clinic wall, so the mark is a single stroke weight at three optical sizes.
