Your program, weights and history stay in this browser on this device. No account, no sync, no ads. Export JSON to keep a copy.
Log your GZCLP session and the coach writes the next one: sets made add a plate, a miss moves 5×3 → 6×2 → 10×1 at the same weight, then a 90 % reset. History, rest timer, kg/lb. No account. Free, local, JSON backup.
GZCLpad is a GZCLP coach, not a workout diary: it decides the next session's weight and stage from what you just did. For a free-form sets × reps × weight log with macros, use Gymac — the two are separate apps and share nothing.
