Most gym trackers are built around logging random workouts. Pully is built around your training plan. Set up your full program - number of week, PPL, 5/3/1, Upper/Lower, or any custom split. Add exercises with target sets, reps, rest times, and grip variants. Then execute it: auto-filled weights from your last session, rest timer, RIR tracking. After each workout, see week-over-week volume deltas and automatic PR detection. Free on iOS. Premium unlocks charts and advanced stats.
