The Firecracker Legacy Beta mobile app (the one with the purple interface) employs a unique recommendation engine, which we have since refined and updated into the more sophisticated algorithm that governs your recommendations in Firecracker MD and Firecracker DO. You can read more about the reasoning behind our recent updates on the blog here:

To get your Firecracker MD or Firecracker DO questions scheduled to sync with your progress on mobile, use the Firecracker Daily Review mobile app, which is currently free for download for iOS.

We plan to phase out the Beta entirely soon, to be replaced by the Firecracker MD and Firecracker DO dedicated mobile apps for Android and iOS smartphones and tablets. The Firecracker Daily Review mobile app is the first step in this direction, which synchronizes with the Firecracker MD and Firecracker DO website. The Daily Review mobile app allows you to complete your recommended questions to-do anywhere, anytime!

If you prefer to stick with the Legacy version of Firecracker on the web, then you can check out the Firecracker Legacy mobile app and/or the mobile-optimized website as your go-to version of Firecracker on your mobile device(s). Feel free to reach out to us within the app, or via email at with any questions, concerns, comments, and ideas!
