The most customizable gym app — built by a gym-goer who actually trains. Now in Simplified Chinese, with cardio/distance tracking, exercise search, and backups.
FitSimp is the most customizable gym app — built by a gym-goer who got tired of bloated logs and rigid templates. Every screen exists to make logging fast and your routine yours.
FOR EVERYONE WHO TRAINS
First-week beginners, intermediates chasing PRs, returners getting back into it, lifters and mixed-modality gym-goers alike. The visual system leans industrial because that's what depth users want. The voice meets you where you are.
BUILT BY A GYM-GOER
FitSimp is made by someone who actually trains. Every feature shipped because it solved a real problem under a bar — not because a roadmap said it should. If you've ever fumbled with a log between sets, this app is the answer to that exact frustration.
DEEPLY CUSTOMIZABLE
- Three themes — Crimson, Warzone, Neon Grind — each with light and dark variants
- Per-template identity icons and a 10-color identity palette
- Build templates exactly how you train: any exercises, any order, your own rest intervals
- Lock Screen widgets and Live Activity layouts that fit your routine
- Pick the look that matches your gym; pick the layout that matches your training
LOG SETS IN SECONDS
- Track weight, reps, and notes per set
- Track distance-based sets for cardio and mixed-modality work
- Search the full exercise library to find anything fast
- Rest timer between sets, visible from the Lock Screen and Dynamic Island
- Heart rate streamed live from Apple Watch
- Auto-saves as you go — never lose a set
TEMPLATES THAT REMEMBER
- Save any workout as a template with its own icon and color
- Repeat last week's session in one tap
- Build a library of proven sessions
REAL HISTORY
