Hi @smcdonald, I’m one of the founders of Open Data Kit and I’ve spent most of the last 10 years(!) trying to make ODK Collect easy to use. I think we’ve done a pretty good job, but there’s always room for improvement.
We have detailed documentation on all the ODK at https://docs.opendatakit.org so I’d start there. If you run into any problems, we have a very kind and active community of 7000+ ODKers at https://forum.opendatakit.org who are ready to answer your questions.
As to your location feature not working, that’s very strange. Please file a support request in the support category of the forum with details on the device and version of ODK Collect you are using and we’ll track down the issue and fix it for you.
