Works as described. With an Android phone, the signal is weaker but doable. Was amazed when it arrived and it was in 2 parts. No explanation except in Scandinavian. Finally, it was determined through Revain Q&A that the extra piece needed to be glued to the outside of the phone to allow the Kardia device to be inserted into the mount from the other side to secure it for a stronger signal. I found it inconvenient so didn't do it, but found it worked while sitting next to my phone.
