An update on our mobile apps

When we launched Firecracker MD and Firecracker DO in August, we planned to release dedicated mobile apps for iOS and Android devices shortly after.  Unfortunately, we ran into two delays and we want to give everyone an update on our mobile apps as we know how important they are to you.

1. Publishing an iOS app requires approval by the Apple App Store.  When we submitted Firecracker MD and Firecracker DO to Apple on September 8th, we expected approval in the standard 7-days timeframe.  After a lot of discussion, Apple finally approved Firecracker MD but rejected Firecracker DO.  Essentially these apps provide the same experience, the major difference being the additional OMM content that DO students are responsible for. Working through the Apple approval process has taken a lot of time and we are still waiting for a response to our appeal.  Until then, Firecracker MD was removed from the app store. Our iOS apps could be approved “any day” from Apple but we know this doesn’t help you as a student better prepare for your exams today.  If we are not approved in the next week, we plan to start developing a more focused review task app that should meet your daily firecracker needs and require less review by Apple.

2. The Firecracker MD and Firecracker DO apps load a lot of review content directly to your device so you can quickly complete your daily tasks and study specific subjects. For students who own new phones and tablets like the iPhone 6, Samsung Galaxy S6, Google Nexus 9, our apps work great.  For older devices, the experience does not meet our performance standards as these devices do not have the processing power we need. This impacts both iOS and Android but until our apps are approved by Apple, the best we can do is release a test version for Android, which you can access here:

We are providing these fully-functional test apps so we can gather as much real-world performance data with the range of devices students use. If you’d like to help test our Android apps, click either MD or DO above, then click “Become a Tester”, and after a few minutes you’ll be able to download the app to your phone.

We know this delay is frustrating for many of you. We put a lot of work into building Firecracker MD and Firecracker DO so they could be accessed from laptops, tablets, mobile web browsers, and dedicated iOS and Android smartphone apps. Until these apps are available, we recommend you bookmark “” on your phones so you can quickly access all of Firecracker using the web browser.

Firecracker is committed to delivering apps for iOS and Android and it remains a top priority for our design and engineering teams.  We will keep you posted on our progress.
