It's usually a pretty big deal when Google releases a new Android app, and that's doubly true this week. Allo is the company's new chat app, which bundles in the brainy Google Assistant for good measure, while Google Travel makes it easy to plan for and make the most of your next trip without putting in a ton of work. Google's own apps lead our latest look at the Play Store's hottest new releases, but they're not alone this week. Also worth a look is the charming Paper Planes, which debuted at I/O this year, while Don't Starve: Pocket Edition brings a popular survival game to Android and Dog Sled Saga turns the grueling activity into a fun arcade game and management simulation. Stickers, games, artificial intelligence--and yes, chat too.
