I am having the same problem. It a great product idea and the hardware was working great until a recent iOS update which has rendered the product useless.
The such a good idea should be let down by an App seems crazy. And the lack of news from the company about an update is poor form on their side.
Their website is still selling it - so you’d hope they are on the case otherwise they run the gauntlet of consumer law. The last thing we CrowdFunder of the thing need is for an App to get them into trouble.
