Rebuilt Optimystic, a visual-acuity testing app my team originally made as an undergrad project in 2019–20.
This version is a native iOS/SwiftUI rebuild and can run on one device, pair two Apple devices as controller + chart, or use an Apple Watch as a remote. Everything stays local with no accounts or backend.
I wasn’t able to get it through App Store review because of the organization requirements around health-related apps, so I’ve open sourced it instead. You’ll need to build it locally in Xcode for now.
Would appreciate any feedback on the code, bug reports, or contributions.
