How do I download to take a look? (Never mind, I found you, but I don't have an android phone at the moment. Still, it's ok to post a link.)
I keep my information as private as a I can, which isn't very private. I use WHIB for location, which I like but whose background location tracking gets silently turned off by Apple during OS updates, causing holes in my data.
I use self-collected data with a very wonky process.
If I ever get around to an API driven data flow I'll probably use Zenobase. The reason is that this service has shown rather unusual "staying power" in our domain. A big risk of API driven data collection and storage services is that they pivot and/or disappear.
