About

Kadd

Features
Read full description

Kadd is your training log and your crew in one app. Underneath, a progression engine that keeps your numbers honest. On top, a feed where you and your friends compete on the work. And now it comes with a coach. TRAIN Fast logging built for the gym floor: sets, reps, weight, plates math, rest timer, and a live view of the session as you go. Follow one of the starter programmes or build your own. The progression engine raises your working weight only when you've earned it, so the number on the bar is always real. KADD COACH (Pro) Tell the coach how long you've got, where you're training and how you feel. It writes today's session from your own data: the muscles falling behind, the kit you actually have (a hotel room counts), the exercises you've banned, the injuries it should work around. Every weight and rep target comes from your logged history, not a template. Rough night? It goes easier. Every Monday it reviews your week and tells it straight. KADD FUEL (Pro) Point your camera at your food. Scan a meal by photo, text or barcode and Fuel reads its calories and macros, set against targets from your own goal and bodyweight. Fix anything with a tap. Estimates stay editable, never dressed up as precise. YOUR CLUB Add your gym friends with an invite code or find them by @handle. Share a session to the feed when you're proud of it, with a photo if you want. Friends see only what you choose to post. Likes, comments, and a leaderboard that resets every Monday. Feeling brave? Opt into the Global room: everyone on Kadd, one board, in or out anytime. THE GRAFT Scoring is built on Graft: it pays for sessions done, habits kept, streaks and personal bests, not for junk volume. A beginner and a veteran compete on even ground, and there's a new winner every week. Milestones mark the lifetime work. HABITS AND HEALTH Daily habits with streaks: water, sleep, creatine, or your own. Connect WHOOP or Apple Health to see sleep, recovery and training load next to your training. Bodyweight log, widgets and a Live Activity for the lock screen. Your training data is yours. Nothing is public unless you opt in, and nothing is shared unless you post it. The club is free, forever. Kadd Coach and Kadd Fuel are part of Kadd Pro. TRAIN HARD.
