Open Piano · The Bench
What’s on the bench.
Open Piano is built one change at a time, in public. This is what’s next, why it’s here, and what moves it.
How it gets made: One unit is one change that clears the whole release lane: build, test on a real iPhone, screenshots, App Store submission. One unit is $250, underwritten in $5 shares. Funded first, ships first. Nothing is for sale: every change ships free to everyone.
