What Jamie wrote
Aaron Parecki released the iOS app that he uses to record his location and use on his website. If you love location tracking but what to own your data this is a cool option. This is only the client though, you have to have a server to send the events to. It would be perfectly paired with a cloud-based serverless API to receive these events, record them and serve them up to other services. Someone want to make that?
