Index of work

Two apps, one shipped and one in beta development. Everything else is in the workshop.

01

SheetSight A Piano Companion

For people who own sheet music and can’t read it. In beta development Show details

Point your iPhone at a page of a real book — curved, shadowed, as it sits on the stand — and SheetSight tells you what’s on it in plain English: the key, the chords, the note range, where your hands go.

Companion, not curriculum.

Workshop

Experiments and prototypes. Some will become apps; most won’t.

§ 2

How the work is made

Three rules. They decide what gets built and what doesn’t.

P.1

Local-first, by posture not policy.

Your data stays on your device because the app is built that way, not because a policy page promises it.

P.2

Honesty over confidence.

Limitations are stated plainly. If something is early, it says so.

P.3

Small, and finished.

Fewer features, done properly. An app ships when it’s finished, not when it’s announced.
