About

Pure Kaos

Features
Read full description

Kaos is the members' app for Kaos CrossFit in Halifax. Your workout, your class schedule, your numbers, and your gym — in one place. YOUR TRAINING See the day's workout with the scaling option that suits you, whether you're going Rx, scaled or somewhere in between. Follow the track you train on — CrossFit, HYROX, Weightlifting or Open Gym — and see the specific warm-up that leads into the lift. Log your result in seconds. The app reads your workout and works out which movements you did, so your history builds itself. Hit a new personal record and it's spotted automatically, with a card you can share. Browse the movement library for standards and demo videos when you want to check your form, and track benchmark workouts and named lifts over time. CLASSES Book a class, see who else is coming, and check the schedule a week ahead. If your plan includes a set number of classes, you'll see how many you have left and when it resets — no finding out at the door. TRAINING AND RECOVERY Connect Apple Health and Kaos shows your own numbers alongside your training: an estimated fitness age, last night's recovery signals, and how your steps, VO2 max and body composition compare to published norms for your age and sex. Your health data is read on your device and shown only to you — it is never uploaded, stored on our servers, or shared with anyone. YOUR GYM The gym feed carries photos, results and the occasional poll. Chat with your coaches and the members you train with. Collect achievements as you go, and see who's made the Committed Club each month. PERSONAL TRAINING Book sessions with your trainer, see how many you have left, and get a reminder the day before. If your trainer writes programming just for you, it appears in the app alongside everything else. MEMBERSHIP Check your plan and payment history, save a card so the next payment is one tap, book an InBody scan, and refer a friend. — Kaos requires an active membership at Kaos CrossFit. You'll sign in with the email address the gym has on file.
