Not at all! In most cases you can choose to watch the workout course videos without connecting to equipment. Keep in mind that when done this way, the app will not be able to track as many data points as if the equipment is connected. Treadmill workouts will lose the functionality of being able to control the treadmill’s speed and incline from the app during video playback if it is not connected.
The Challenge mode and the Indoor Workout - Free Mode are the only modes in the SunnyFit – For Home Fitness app that requires Bluetooth-connected equipment.
