According to the requirements posted on the app page at Play Store website, the software requires Android 3.1 and up and it's listed as being compatible with Galaxy tab 8.9, Galaxy tab 10.1, Galaxy note 10.1. These devices are listed as possible compatible devices. Theoretically, the app should work natively without any issues, but if you encountered bugs, then you should report them to the developer.
Use the following email to send him an inquiry: kcsteve8580@gmail.com. Based on my knowledge, I believe the software still requires an update for the new Android OS.
