I use it as my primary—while I ride—bike computer, and it’s works really well for that on a Shimano 11 speed rim brake Di2. I come from using Shimano’s Flight Deck bike computer (when mechanical) and this is the natural progression from that. Highly customizable, rudimentary d-fly switch control, perfect for on the fly computing. Not quite stable enough to solely be relied upon to track your rides if you don’t want to lose a ride every now and then, but hey, it’s on my phone, so I run Cyclemeter in the background for that. I love that it—like Flight Deck—displays what chain ring and cassette gear I’m in (if you tell it to). I also love that it displays my sensor battery status (Wahoo speed and cadence, Watch HR, and my Di2 battery status). Other than providing a nice picture at the end for the record of the ride, its map function is completely useless. But hey, it’s on my phone, I’ve got Google Maps for that. I bought an iPhone 13 mini to use with it because that’s the smallest and lightest iPhone with a decent battery life. Quadloc mount. With a new battery in the 13 mini it can easily go 6 hours without worrying about battery life—and that’s streaming Bluetooth to my AirPod pro’s, running gps on at least two apps constantly, with the screen always on, and with an Apple Watch connected, a BT speed sensor, BT cadence sensor, and a dongle converting and broadcasting the Apple Watch HR data to BT HRP. If I had a power sensor it would display date from that as well (I don’t, but I’m looking at them on eBay which is a bad sign that I will sooner or later). I understand that it also works with e-bikes, but I can’t speak to that. It has its strengths and weaknesses, but its strengths are so strong that they far outweigh its shortcomings. It’s silly to use a dedicated head (that costs $$$) and is heavy, when you have your phone with you anyway and This is a really good app for that.
