Android phone app that records trip average speed AND moving average speed

I used MyTracks for years, but it has started to tell me than on a ride of an hour or more with stop lights, re-grouping waits, trip time and moving time are within 20 seconds of each other! I have not been able to find any setting changes that can fix this. At the end of a ride I would like to know MPH average for the whole ride and MPH average moving. I have looked at screen shots of a lot of apps that seem to do trip time average speed only.

Thanks....Don in Austin

Since average speed has to do with "motion", I fail to see the relevance of including "stop time" when doing a calculation involving "average speed". This would kind of be like telling your boss that you worked an extra two hours and when he/she asked you what you did in those two extra hours you tell him/her that you had two hours of coffee breaks.

Regardless, your android has a calculator. Take the total mileage of the route and divide by the total time of your choice ( in hours ) and you have your answer in MPH. ( Not that it will mean anything if you include the time you lollygag around but hey, whatever makes your day FWIW ).

A problem with MyTracks is that it is no longer calculating time at stoplights etc. properly. I could just look at the time on my phone for total trip time, but I don't know how much time was spent at stoplights and stop signs. And, despite that some might think it meaningless, I AM interested in the total time for my commute into work and average speed with stop signs and stop lights averaged in.

I think I downloaded Mytracks at some point but deleted it because it wouldn't do what I thought it would do. Doing speed/timing calculations by way of a phone GPS system is likely not going to be really accurate IMO anyway. If you're poking along riding up a long hill at 5 mph ( or less ) you have to wonder how accurately the app ( via the satellite signal ) is going to be able to triangulate the calculation for your speed ( seeing that many times it has a problem just trying to track you period. I think that all of this just goes with the limitations of consumer electronics. I think when NASA tracks objects in space they are likely using more sophisticated technology.

Anyway, I do have Trimble Outdoor Navigator on my android. It does tracking and has stats for avg.speed, trip time and such. It wasn't free though and I really haven't used it enough to know whether or not it is accurate. Sorry I couldn't be of more help. Sadly you might have to just use a standard bike computer as I'm sure there are some that will include both total trip time and total moving time. I love the android stuff but I'm not giving up my bike computer because it's just too useful of a tool.

Good luck, I hope you find something that works.

If you upload the GPX track to a website (or just your computer), you can get that information. At Connect.Garmin.com, I get both moving and total time (regardless of whether I use my phone with MyTracks or my Garmin GPS).

GPS on your phone should be quite fine as far as accuracy goes. I find when I ride the same route on different days, I get very close total distances, etc.

I will look into Trimble. Don't mind paying a few $$$. Regards bike computer, I have 7 bikes and they already all have various different computers!

Sorry, my bad. If you're a government worker you probably do get paid for coffee breaks. Sorry if that was confusing.
