When connected it's OK, however. .. This highly configurable app works great when it is connected to the PC. However, in a typical work day, it disconnects every 15 minutes or so. Requires it to reconnect , which takes about 8 tries each time. Now with the latest version, it sometimes says that it is connected, but the screen is blank and you have to exit and try again. No idea if it is the app or the Bluetooth connection. I would rate it one star higher if it could stay connected all day.
