I'm guessing you've already searched the Google Play Store for the app on their Tablets and tried to install it? The only information I got online was:
4.0 and up
It doesn't say if it's compatible with Tablets, but I can tell you if you try to install it and it's not, you'll know.
If you can leave one of your smart phones with them, it looks like that's your next best option. I don't think there is a secondary app that can be used with the device.
