Piggybacking here but the FAQ is painfully vague. On the question of what phones does it work with their answer is:<p>&gt; Beartooth pairs with both iOS and Android smartphones, as long as the operating system is up to date.<p>Which is a pretty much useless statement on Android especially since they would know what API level their app targets...<p>It certainly sounds like it&#x27;ll use Bluetooth though and makes sense as a bridge between the two devices. The only other real option would be Wifi or if you wanted to be weird for the sake of it you could probably do it through NFC.<p><a href="https:&#x2F;&#x2F;beartooth.zendesk.com&#x2F;hc&#x2F;en-us&#x2F;articles&#x2F;217369867-Which-phones-does-Beartooth-work-with-" rel="nofollow">https:&#x2F;&#x2F;beartooth.zendesk.com&#x2F;hc&#x2F;en-us&#x2F;articles&#x2F;217369867-Wh...</a>
