Yes, you can access BarMax from your computer or laptop, one phone, & one tablet. Unfortunately, we don't allow for students to use the course on multiple of one device.
Still, you can log into the app on another device whenever you want. The app will recognize the new device and ask you if you want to associate your account with the new device, and once you select yes, you'll be good to go. That's all you need to do to use the course on a new device.
If you need to go back to the old device for some reason, delete the app, download it again from the App Store, and then log in as though it's a new device. It'll be an identical process and the second device will then lose its access.
Please note, however, that constant switching back and forth between devices will flag your account for sharing and your access will be blocked.
