Transform your classroom into a game and see how your studentsâ deepened engagement can supercharge your lessons.  1 Seeing silent students find the courage to speak up because they can earn extra XP, or watching students smile when they get back a good result ... those moments are worth a lot, and thatâs what I like about Classcraft.. - Jeroen HeremansBelgium@geekmyclass.

Pebble Time has four buttons. The left button is called the 'Back' button, which is initially used to Power on your watch (press and hold it for 3 - 5 seconds), and subsequently used for returning to the previous screen or entering your watchface app from the main menu.
Pebble's two apps -- one for Android 2.3 or later and the second for Apple devices running iOS 5 or later -- enable everything from initial setup to push notifications. There's no user manual in the box, so you'll need to download your respective app to get started.
