Firecracker MD and Firecracker DO are our newest flagship products, available on the web at med.firecracker.me/app. Firecracker DO includes all of the content, questions, and features from Firecracker MD, in addition to our osteopathic materials and COMLEX practice questions. If you are a DO student who signed up for Firecracker MD, then upgrading is free; just send us a message at techsupp@lww.com and we'll activate the osteopathic materials in your account.

The web-based versions of Firecracker MD and DO are supplemented by the free Firecracker Daily Review mobile app, which is a companion product that is free for download on iOS and Android smartphones and tablets.
