Double progression, done for you.

Hit the top of your rep range and Rung steps the weight up — sized to the lift and snapped to plates you can actually load. Slip below it, and it tells you to hold. Grind down repeatedly, and it eases the weight back before you stall.

One quiet line under every exercise. No spreadsheets, no percentages to remember, no coach talking at you.

Mid-workout, hands off.

Log a set and the rest timer runs on your Lock Screen and in the Dynamic Island — with your suggested next set beside it, so the phone stays in your pocket between sets.

Proof you're climbing.

A weekly review and a monthly report, computed on your phone from your own log: volume, sessions, records, and where a lift has quietly stalled.
