Does something that no other software can do.
*UPDATED* Xert is the only app that I found that can connect to the Powertap P1 pedals using Bluetooth on my Nexus 6P and actually add up the power from both pedals! I compared with the readings from my ANT+ dongle on my PC in Tacx Trainer Software and they match. This is a great app that deserves 5 stars! The online analysis seems very nice too, but I didn't test that part very much yet.
