Overview
What is NOXA?
NOXA combines strength training, HIIT and run tracking in one app — with Apple Watch, Live Activities & Dynamic Island, Apple Health sync and a voice coach. When running, users conquer territories on an H3 hex grid with RunTurf and race their earlier runs in Ghost Runs. NOXA Pro unlocks advanced features as an in-app subscription. A separate trainer app for coaches is in progress.
