wow I'm impressed you got that all hooked up! This was definitely not ready for prime time yet!
I just fixed up https://compass.p3k.io/ since I'm going to be using that starting next week. If you want to continue using these, you should switch to the p3k one, since the other one you found will likely be deleted occasionally.
I haven't documented the "trip" feature yet, but you likely saw it if you used the app. I'll have docs soon, but basically it makes a Micropub post to your server when a trip is completed. This is how I'm going to be tracking my bike rides and runs from now on!
