Most stop at 99.
C100 is built on one rule: complete 100 reps, however you split them.
The Standard
100 reps. One movement. Finished.
No shortcuts. No almost. No exceptions.
How it works
- 01
Choose your movement.
Pick from the built-in library or your own custom exercises.
- 02
Complete 100 reps.
Split across as many sets as you need. The app tracks reps remaining, not a fixed set/rep prescription.
- 03
Return tomorrow.
Your history and progress carry forward automatically.
Features
01
The 100-rep standard
Every exercise has one target: 100 reps. Split it across 4 sets or 14. The app tracks reps remaining live.
02
Three-tier timing
Independent workout, exercise, and set timers run simultaneously. Always know your pace and how long each set took.
03
Pause & resume
Step away mid-session. Pick up exactly where you left off, with paused time excluded from every timer.
04
112-exercise library
Chest, Back, Shoulders, Arms, Legs, Core, Cardio and Other. Plus fully custom exercises.
05
Build your own programs
Assemble reusable training plans, or start from a template: Full Body, Upper Body, Lower Body, Core.
06
See your last time, mid-set
Reps, sets, and average weight from your previous session, shown next to the set you're about to log.
07
kg or lb, your call
Switch units anytime. Every logged weight in your history converts automatically.
08
Private by design
No account, no login, no server. Every rep you log stays on your iPhone.

A 100-square grid fills to 99, then the 100th square completes. The video then shows the C100 app: one rule, 100 reps, split however you like; workout, exercise and set timers; a library of 112 exercises, your own programs and your history; the exercise and workout complete screens; and that there is no account, no login and no server. It ends with: Stop rounding down. Start finishing. iOS, coming soon.
