Why CompoundLift
Lifting brain. Zero friction.
Traditional gym apps lock you into rigid workout plans or force you to tap dozens of tiny menus between heavy sets. CompoundLift is built around how lifters actually train.
02
Volume First
Loyal to muscles, not splits
Swapping an incline dumbbell press for a machine isn't a deviation. CompoundLift tracks total weekly volume per muscle group with multi-muscle assistance credit.
03
Instant Tap
Ghost-text previous values
Your previous session's weight and reps automatically pre-fill each row as subtle ghost text. A single tap on the checkmark accepts and logs the set.
04
Smart Generator
"Fill my gaps" workout builder
Let CompoundLift assemble a session targeting the exact muscle groups that are behind this week's volume goals. Tap once to build, or ask the mic.
05
Delight
Automatic PR celebrations
Hit a weight record or a bodyweight rep personal best? CompoundLift celebrates immediately with haptics, celebratory visual feedback, and trophies in history.
06
Privacy
100% Local-first & offline
Gyms and basements have terrible signal. CompoundLift works fully offline with instant on-device IndexedDB storage. No accounts, no ads, no trackers.
