Nice, versatile app, clean look with logical layout. However, I don't appreciate having ads on an app when I paid for their device already. Stop this practice, and I'll change this review to five stars. UPDATE: ads stopped appearing and have stayed gone for several months. SECOND UPDATE: Less than a week after writing the above and adding stars to my rating, ads are back, presumably with the app update. App is now buggy and loses workout data constantly since the update. Down to one star UFN
