I've been logging my rides with MapMyRide since last summer as well as using the mapping feature to plan out other fitness rides. This year, I have an Android phone and last week, downloaded the MapMyRide app. However, I've had a couple of issues with it but I don't know if they are related to GPS in general or the app.
The Auto Pause feature is nice since I like to know my time/speed on commutes independent of waits at intersections but twice in the last 6 days of using the app, the Auto Pause has not resumed: the first time, it missed about 3:30 at the beginning of my ride and today, it missed the whole of my 45 minute commute in to work. The other reason I enabled the feature is because I use long fingered gloves so I have to take off one glove to activate the app, then put the phone in the backpack, put the backpack on my back and get it settled, put my glove on, hop on the bike and then take off assuming that the Auto Pause will pause during all of that and then resume when I take off.
The other issue is that my ride home ranges from 16.45 to 16.99km according to the app but I can't imagine that I weave that much to add 540meters to my ride.
I'm not set on MapMyRide so if anyone has any suggestions for a better app, I'm willing to switch.
