The problem
Scale is hard to feel. Strata lets people pinch and drag through maps of the cosmos and of history, and compare the gap between any two points, so very large and very small numbers become something you can see.
What I did
- Designed and built a zoomable map engine rendered with Skia in React Native
- Wrote and structured around 900 history events across several map packs
- Moved the app from paid to free with eight optional in-app purchases, while keeping every pack for original buyers
- Fixed a 2.1(b) rejection caused by Apple's sandbox reporting the original app version as "1.0" for every account
- Added a home screen widget and a web version from the same codebase
What it shows
- Performance-sensitive rendering and gesture work in React Native
- Careful monetisation changes that don't break existing customers
- Debugging App Store review issues that only appear in Apple's environment
