iPhone
New: share the workouts you choose with your trainer on KATACHI +. Weight, photos and Health data are never sent. Log sets in two taps. No ads, no tracking.
Numbers and photos, together.
KATACHI brings your lifts, body weight and progress photos into one calm, private place, so you can look back on how you’ve changed.
LOG IN SECONDS
Pick an exercise, enter weight and reps. Or type a line like “Bench Press 135lb 5 reps 3 sets” and it’s read for you. A gentle target from last time is suggested. Running is logged too, by distance or by speed, time and incline.
TRACK YOUR BODY
Weight and body fat trends, goal weight, and optional import from Apple Health.
PROGRESS PHOTOS
Take front, side and back photos with a self-timer camera, with your last photo faintly overlaid so every shot lines up. Compare before and after, and export a timelapse. Faces can be pixelated automatically when you share.
MONTHLY LOG
A one-card recap of your month — training days, volume, weight change — made to share or keep.
TOOLS
Plate calculator, rest timer with Live Activity, estimated 1RM, weekly volume by body part.
UNITS THAT FIT
kg or lb, cm or ft/in, km or miles, ml or fl oz — your choice.
PRIVATE BY DESIGN
Your records and photos stay on your device. No ads, no tracking. Optional Face ID lock and iCloud backup with Pro.
FREE, AND PRO WHEN YOU WANT MORE
Free to use with the last 10 days visible. KATACHI Pro keeps your full history, with Apple Health import, iCloud backup and shareable Monthly Log cards. Choose a monthly or yearly subscription, or a one-time purchase: pay once, no renewal.
KATACHI is a logging tool and does not provide medical advice.
