You can always control your Wave using the buttons on the device, but the app lets you do so much more. Through the app, get access to more features and options to create personalized relief for hot flashes and other menopause symptoms like sleep disruptions, chills, and increased stress. Change how long your sessions last; choose specially designed waveforms for different situations; reprogram your Wave’s buttons for shortcuts to your favorites; and track your patterns over time. The app also lets you keep your Wave up to date with new features and improvements.
