Yes we do! If you want to do the same questions that Firecracker recommends on the legacy website, but in a mobile-optimized interface streamlined for quizzing, then you can check out legacy.firecracker.me/m/

This site is not a dedicated mobile app; however, its convenience and the simplicity of its design should help you to hammer out questions efficiently. The questions you do on the legacy.firecracker.me/m/ mobile-optimized website will chunk away from your daily recommendations on the full Legacy website, which you're also welcome to check out on your mobile device(s).
