Read full descriptionHide full description
Catalyst Coach is the training app for clients of Catalyst Performance, the healthspan and longevity training studio in Manulife Tower, Singapore. Your coach writes your programme. The app puts it in your hand. Open the day's session, follow each exercise with its demonstration, and log your sets, reps and loads as you go. Your coach sees the work and replies with notes on it. Progress is measured. Your 4-Pillar Healthspan Assessment results, your body composition scans and your training history sit in one place, so you and your coach can see what is moving across strength, stability, cardio capacity and body composition. If you allow it, the app reads daily values from Apple Health, such as steps, sleep, resting heart rate and VO2 max. It can also read the daily values from Oura, WHOOP or Garmin if you connect them. Your coach uses these to set the training load. The app never writes to Apple Health, and your data is never used for advertising. Reminders and coach notes arrive as phone alerts. Catalyst Coach is for current clients of the studio. You cannot sign up in the app. Your coach invites you by email after your assessment. To start, book a complimentary 30-min consultation at catalystperformance.sg. Show up. Do the work. Repeat.
