Nice concept - doesnt work well though

I bought this app after I got an Apple Watch. It worked for a while - then stopped. If remove the association between my MBP and my iPhone in the knock apps, then re-associate them it will work for a while again. But it hasnt worked with my watch in ages.

Cool concept, and when it works its nice, but considering the cost I dont think the value matches the price.
