# iOS GPS logger and compass

[aaron parecki](https://aaronparecki.com)’s ([@aaronpk](https://twitter.com/aaronpk)) *[iOS GPS logger](https://github.com/esripdx/GPS-Logger-iOS)* works pretty well in conjunction with *[compass](https://compass.esripdx.com)*. with one exception though: the underground.

i found *compass* in the footer of aaron’s new [telegraph](https://telegraph.p3k.io) web app, where it’s listed as part of the *p3k suite*. compass at p3k.io didn’t work though (it threw 500 errors). so i uncommented 2 lines in [AppDelegate.m](https://github.com/esripdx/GPS-Logger-iOS/blob/master/GPSLogger/AppDelegate.m#L21) to use *compass* at compass.esripdx.com instead of compass.p3k.io.
 

to make the app upload the location data i had to add a *write token* that i got from compass.esripdx.com/settings/[database name]. with those hardcoded credentials the ios GPS logger sends it’s data to *compass* just fine.
 

nice work aaron, thanks a lot for opening your tools to the public!
