The main feature of the app is that you will be able to adjust your Boost fin’s settings to comply with your needs and your style. Each fin comes with pre-set modes that you can customize for different types of styles and waves. You can play around with the setting to find just the right mode for yourself. Remember, more power equals more battery usage and vice versa.
