Microsoft's Garage team has tried to solve many everyday problems with its experimental mobile software, but it's now tackling one of the most common: how do you get your friends together for a night on the town? The group's new Tossup app for Android and iPhone gives you a simpler, shared experience for deciding on where you're going, when, and who's coming. You only have to ask your friends for a vote, and Tossup will automatically plug your decisions into your calendar. Is this a one-trick pony? You bet -- but that might be all you need if you don't want to set up a Facebook event (or juggle multiple conversations) just to head out for Korean barbecue.
