Exercise library
Create exercises with descriptions, reference photos, and links so technique notes and cues stay attached to the movement.
Product
Kachai turns workout planning into a clean weekly loop.
The app starts with editing your exercises and weekly schedule, then makes it easy to complete workouts, log what actually happened, and review progress later.
Day-by-day programming
Assign exercises to weekdays and set default weight, sets, and reps for each program day.
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.
