I don't see how this app is using QCAR. It seems that it just relies on the accelerometer and not a marker to get the camera orientation.

I downloaded a game once which uses this technique to create "Augmented Reality". I put this in brackets because it's user experience is pretty bad. The accelerometer output is jittery and to dampen that you have to use a low pass filter. This creates a noticeable delay between the camera movement and the 3d content. Furthermore, it suffers from "wandering" as the 3d content is not referenced to a real world object. All in all, the accelerometers make really bad inertial reference/navigation systems. They just aren't accurate enough.

So in my opinion, if you want to use AR, then using markers (or marker-less if features from the live camera stream are tracked such as with PTAM) are the way to go.
