The Cola Bubbles feature in the Cola messaging app will introduce additional interactivity and functionality. For instance, rather than to invite someone out via text, just send them a Bubble with three times whenever you are available, and they can pick from a range of options that convey the message back. If you are so busy that you can’t even type a reply, just share your location with a time period locked in (ranging from 15, 30 or 60 minutes).
Different kinds of Bubbles comprise of polling and shared to-do lists, and the whole point is to make them accessible from a text message conversation, as opposed to installing and running even more apps. Heck, even those without the Cola app can receive Bubbles, now how about that?
