I use MapMyRide app (MVP subscription) with Android phone for my main device for stats. Cateye wireless bike computers work great for me except when I use my Niterider lights. The headlight interferes with the signal going from the bike computer to the sensor. I tried to wrap the light with foil, but that didn't help.

I use the Cateye computers for backup. I have two road bikes, both with the Cateye Micro MC100W model. I use Cateye Strada CC-RD300W for my gravel bike and 29er. The Strada is the more accurate of the two. It's very close to the MapMyRide GPS stats even on long rides. The Micro is a good computer too, but it's usually off from the GPS (after the ride is done) by about a couple of tenths of a mile on short rides under 20 miles... several tenths/mile on long rides. I may need to re-calibrate my wheel settings on the Cateye Micros. I went by the 700 x 25c settings provided by Cateye and I think they are off a little.
