UAC - Universal Athletic Club is a lifestyle app designed for iPhone users, developed by SmartWeights Inc. This free app offers users the convenience of checking in to the club and accessing various club resources. Users can easily view class schedules, purchase and book programming, schedule appointments at BLU Salon & Spa, order shakes from the cafe, and more.

One of the notable features of UAC is its integration with the Health app on iPhones, allowing users to sync nutrients and workout data seamlessly. To enable this functionality, the app requests permission to access and update nutrients and workout data stored in the Health app.
