My original iOS Brainiversity brain training game was made using Corona SDK and Lua. I have rewritten it from the ground up using #Swfit and #SwiftUI - here is a comparison between the original 2014 and the new 2023 version. Fun fact - I made the very first version of Brainiversity for PC in 2007, a year after Nintendo released Brain Age in the US.
The new version is also playable on Apple Watch and will (hopefully) be out by the end of the month!
