Nearpod is built for the 1:1 class, giving the teacher power to push out videos, quizzes, and assignments right to students' devcies.
You can create a quiz, interactive slideshow, or activity and immediately put students to work on it. They are not limited to multiple-choice activites as they can use a stylus or finger to write and draw within the app.
Nearpod officially supports the Nexus 7, 10, and Samsung Galaxy Tab 7, though it may work on other devices.
The mobile app is free, with Nearpod offering a paid tier for schools that want additional storage and other services, like a self-paced feature called Nearpod Homework.
