You've hit several good points here! This looks really cool. I've never used something like this, but I'm seriously considering buying it. I love the single price up front and the privacy of not sending my tracking data to some unknown server on the internet.

My only complaint is that I absolutely hate the name. I don't even know how to pronounce it. "Cube-serv?" "Queue Observe?" Don't make me think. Also, I'd be embarrassed to try to say the word to someone else when telling them about it. "Looks like a really cool app! What's it called?" "Oh, it's um... Q... Uh... Cube..., uh I don't know. I have to go." And even if I could pronounce it, trying to spell it for someone so they can look it up. Ugh. Forget about it.
