What is that PHONE APP above the kb being used?

Does anyone know what that small display tablet or what phone app is being used in this video?
and what it's used for with the Roland GO Keys?

can anyone translate the text below the picture?

I-phone not included.
You can play along your favorite songs or tracks.
The instrument comes along with USB Midi for even more possibilities.

But it must be some kind of APP to control the keyboard styles right what I wanna know is what app it is??

anybody??????

... I also emailed the store that did the demo waiting for a reply too.

The Phone app that is used is called
garage band. Its a free app....
Just heard back from the person who is playing the demo.

This keyboard intrigues me too, especially the compact size, it might be worth its weight and cost as a MIDI controller.
However, I don't believe it's an arranger in the traditional sense (styles that follow the chords you play.) Instead the accompaniment is "loop based," whatever that means. I guess it's like a collection of multipads?
I would like to see someone doing a song cover on this thing, without the aid of a tablet or iPhone. I searched for a while on YouTube and didn't find anything. If anyone comes across a video like that, please post it!!

Ted you can loop 8 patterns (1300 on board loops based on 22 rhythm types)

And yes you can switch from looper to chord and play chord changes... You can also save your loop and overdub 8 more tracks..

Other plus Bluetooth and USB audio and Midi.. Robust speakers that sound great..

And a decent key feel...all for under $300.
