They promised a companion app during their Kickstarter campaign but since then (over one year now), they keep saying that their app "is in the final stages of beta testing," which seems to be an empty lie. Backers inquiring about the app on Kickstarter get ignored, comments or remarks about the app in their FAQ section get deleted (the worst thing a company can do), and the same goes for negative product reviews in response to their aftersales emails which never get published on their website.
So basically, as a customer you are allowed to voice your opinion as long as it is positive, otherwise, you get ignored or deleted. Not a very modern or democratic way to manage a company.
And please don’t tell me about their refund policy. I kept the device after my purchase as they continued to lie about the app coming out soon, and now it is just another worthless piece of useless technology in my basement.
My advice: DO NOT BUY.
Bottom Line: Yes, I would recommend this to a friend
