I'm using Wahoo on an I phone 10 which I have mounted with a Rokform Mount Works great : I also have the Duotrap Sensor with a Ride time Computer : One gives me a Visual The other I record the Trip with . Maybe because I have a New Phone I don't notice much battery drain. I get the thing Started and then minimize the window : I could get by fine with just the Bontrager Sensor and Wahoo on Phone.

I read complaints the Duotrap doesn't work consistently . Yes it does : You have to turn it on before you start peddling : Just spin the back wheel and it sets the sensor. Sometimes it works without doing that . Rarely though . Unfortunately the Instructions don't tell you that > I figured it out accidentally : Since then it works perfectly

I ride pretty much in a 100 mile area : Often I just leave from My House : There's a Bike Trail that's at least 50 miles only 5 miles from where I live : Country Roads making life easier : Just watch the Inner-sections Soooooo GPS isn't a feature I've even used so far.
