Hey brotha! For an Android App, I would highly recommend using RunnerUp! I've been using it for a while.

Currently, you can save any GPX / TCX (gps tracking files) to your phone for upload to EXHAUST, and you can also sync the app and connect to Strava / RunKeeper/ Nike+ / and a couple others.

My short term plan, since this is an open-source app (see git here) is to update the code w/ a pullrequest so you can upload directly to EXHAUST from the app... Eventually, maybe make a fork of the App to change the front-end so it can be a launchpad for a new EXHAUST android app...

I know you got some JS skills, bruh. If you wanted to sink into this -- it might be rewarding...
