Mountainside Fitness is a free Android app developed by Smart Health Clubs. It is a lifestyle app in the Health & Fitness subcategory and is designed to help members of the Mountainside Fitness chain of health clubs get the most out of their fitness goals. The app is a one-stop-shop for all your fitness needs, allowing members to track their workouts, set personal goals, and register for classes.

The app is user-friendly and easy to navigate, allowing you to check class schedules at all locations, add a class to your calendar, and register for Peak Performance classes. The app also allows you to sync with popular fitness tracking devices, such as Fitbit and MyFitnessPal, and track your progress both in the club and on the go. Additionally, there is no need to carry a membership card anymore, as members can check in to the club using the app.
