To use Boom Cards, you must be connected to the Internet. Boom Cards play on modern browsers (Chrome, Safari, Firefox, and Edge). Apps are available for Android, iPads, iPhones, and Kindle Fires. For security and privacy, adults must have a Boom Learning account to use and assign Boom Cards. You will be able to assign the Boom Cards you are buying with "Fast Pins," (play provides instant feedback for self-grading Boom Cards). Fast Play is always a free way for students to engage with Boom Cards decks. For additional assignment options you'll need a premium account. If you are new to Boom Learning, you will be offered a free trial of our premium account.
