Not a gym tracker. A muscle tracker.

Track every muscle.
Build every rep.

Most apps count reps. KasMaker tracks muscles. See what you've worked on an interactive body map, detect PRs, and get smart training insights.

Everything you need.
Nothing you don't.

Interactive Body Map

Every exercise is mapped to primary and secondary muscles — bench press lights up your chest, triceps, and front delts. Tap any muscle for stats and exercise recommendations.

PR Detection

Personal records are detected automatically and celebrated in real time. Never miss a milestone.

Progress Charts

Track strength gains over time with weight and estimated 1RM charts for every exercise.

Smart Rest Timer

Auto-starts when you complete a set. Tap to adjust duration. Stays out of your way.

Training Insights

Push/pull balance, recovery tracking, volume analysis, and progressive overload suggestions.

800+ Exercises

Curated database with instructions and images. Filtered by your equipment and muscle group.

Routines from Real History

Build a routine from a workout you actually did, not a blank template. Edit freely mid-session — your routine and your session stay separate.

Customizable Recovery Window

Set how long a muscle stays "trained" on your map — 3 days, 10 days, your call. The map fades in time with how you actually train.

Your muscles.
Always visible.
