Planning a hangout shouldn't take 47 messages. "gather." is the social scheduling app that ends the "when are you free?" group chat loop. Connect your Google Calendar, propose a few times, invite your friends - everyone votes, the best time wins, and the event is confirmed. Done. No more back-and-forth. No more dropped plans. Just made plans. Friends don't need to download the app to respond, they vote from a link in their browser. Free. iOS.
