Problem
Many workout apps gradually turn exercise into data entry. The useful information here is deliberately smaller: the exercise, what I lifted recently, and what I should attempt now.
04 / iOS / Swift
A workout tracker that stays out of the workout.
I didn’t need another fitness platform. I wanted a small tool that could record sets, show recent performance, and give me enough context to decide what to do next.
Small interaction loop
- 01See recent work
- 02Choose the next target
- 03Record the set
- 04Return to the workout
Scope
The main design constraint is intentional absence. The workout model and interaction loop stay small so recording progress does not become a second activity competing with the workout itself.
Today or this week
See workouts for just today or the whole current week, then tap into an exercise to complete it.
Pounds or kilograms
The app supports a preferred weight unit and keeps both unit values in sync for smoother logging.
Workout history and charts
Kachai records workout entries and charts volume over time for each exercise.
Progress selfies
Save progress photos from the camera or library and review them alongside the exercises completed during that same week.
Designed for consistency
Less admin, more training continuity.
Kachai is not trying to be a giant fitness platform. It is a focused personal tracker for lifters who want a repeatable plan, accurate logs, and a simple way to see progress compound.
