No email, no signup wall, no "create an account to continue." Your data lives on your device, backed up to your own iCloud. BUILT FOR YOUR GYM, NOT A GENERIC ONE Every gym is different. Yours has that one plate-loaded machine nobody else stocks, or a cable setup with its own quirks. GymHack lets you add your own exercises and your own machines — name them, photograph them, tell the app what they count as, and train with them like any built-in movement. And your AI Coach — a PRO feature, currently in beta — knows about them.
