RIRLift: Hypertrophy Log

RIRLift is a focused hypertrophy logbook for lifters who train with Apple Watch and care about reps in reserve, repeatable routines, and weekly volume.

Build repeatable routines on iPhone, start planned workouts on Apple Watch, and log each set with load, reps, and RIR without digging through social features or generic fitness noise.

Designed for serious lifting:

• Start lifting in one tap. No sign-up, syncs across your devices
• Apple Watch-first workout logging
• Planned routines with sets, rep ranges, rest timers, and target RIR
• AI Coach: the load for your next session, worked out from your own numbers and moved by the RIR you log. It runs on your phone, nothing leaves the device
• A finish line for your program, and the week you are in counted against it
• Fast exercise replacement when equipment is taken, with Coach's load on the picker
• Warmups, drop sets, rest-pause work, and failure finishers
• Cardio and conditioning logged separately, never counted as hypertrophy volume
• Weekly hard-set volume by muscle
• Workout review, notes, and history
• Custom exercises for your own movements
• Optional Apple Health workout saving with your permission
