If you have a phone with a USB-C port and can wait, they are supposedly going to release a version with a USB-C connector some time next year. I have a Nexus 6P so I asked the question using their contact form and they told me they were planning on releasing a USB-C version next year, but did not have a release date yet.
Also $1k seems like too much, at that point it's as much as a Therm-app for similar features, and if they're the same price I might as well go with the company that has a US presence so I can complain if something goes wrong.
