The product they write/develop is called Cola Bubbles, you can find out more here. Nice timing on how it was posted on the Apple iTunes Store on his birthday last Friday. It’s free so I don’t get any money for endorsing/plugging it.
What does it solve? This is often the question I have because there’s no shortage of useless crap fighting for space on my phone. Bubbles consolidates several things into a conversation: polls, calendar (make appointments), photos/video (Messages already does this, I know), location/map and the to-do list. The goal is to cut down on what they call pogo sticking between apps. What I like that Messages doesn’t do is Bubbles allows you to add/subtract people from a conversation, the former makes the group a permanent situation.
I’m on it so invite me to try it out.
