If a course has the note "Compatible with mobile devices", it should work on a mobile device. If it doesn't have that note, you can access your account and take quizzes, but your courses' learning material may not be viewable and courses cannot be paid for. Even if modules can be viewed, the completion information may not be sent back to our system. This would mean retaking the course with a desktop or laptop computer instead.
Our site is capable of hosting courses for mobile devices and a few courses are now HTML5 capable. We expect this number to grow over the year. However, many of our courses were developed to use Adobe Flash. Apple has not allowed Adobe to run Flash plug-ins on the iDevices. If a device has Android OS Jellybean 4.1 or newer, it will not run Flash. Older Android devices may work for you if you have Flash installed.
