Seems incomplete
And it does, but...
You cannot actually play the script on your screen without recording video, so if I want to stick my iPad on a teleprompter stand and video with a different camera, my iPad will be recording video, even though the camera won't be pointing at me.
It's a ridiculously simple flaw, and one that would be so easy to fix, yet this app has been on the app store for over 2 years, and nobody's thought to fix this.
In fact, a mistake like that should never had made it to the app store, as any reasonable software tester would have spotted it right away, and the fact that they didn't indicates to me that the software wasn't properly tested at all, leaving me with little faith that the software can be trusted to work as you would expect.
On top of this, when you use the app as a prompter on the device you're using for filming, you lose all control over camera settings -- there is no way to set or lock exposure or focus, for example, meaning your picture can change dramatically during filming.
It does its basic job, and it is usable, but there are vastly superior apps out there, so I wouldn't bother with this one unless it gets quite a radical overhaul (or if you have an old device and none of the alternatives will work with it.)
