Dual n-back trainer ported from Brain Workshop 4.8.1 to a Rust and Tauri desktop app and a native Kotlin Android app, with every trial, press and reaction time stored for statistics. GPL-3.0-or-later.
How it knows: Two ports with no shared code are held to one behaviour by golden JSON fixtures exported from the Rust core, with the random generator reproduced bit for bit, so the same seed gives the same session on desktop and phone.
