I like it, especially with the ability to import Google Location History. I also like the name, assuming I'm pronouncing it right :)
I'm currently using Home Assistant for keeping track where I've been, but the update frequency is rather low (to save my phone's battery, presumably, despite often having the little location access indicator on screen).
Perhaps someone here has any experience with OwnTracks/Overland? This looks pretty good, but I'm curious about the extra battery usage.
