Rung.

Your next set,
already decided.

Rung watches your sets and suggests the next weight and reps. Walk up to the bar knowing exactly what to load.

No accounts, no cloud. Your training data never leaves your phone.

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.
