I think the point others are making is that unlike, say, your height, "vision" is actually a combination of raw input from the eyes, and the subsequent processing of that input by the brain.
Therefore vision can be improved by making the eyes better - contact lens, lasik, etc - or by making the brain better - presumably what this app is doing.
A (very poor!) analogy would be how you you can use post-processing in software to capture better images, even without changing out the lens or the camera. Upgrading the algorithms in the software will result in better images.
Note that I'm pretty skeptical of the claims as well, but I also acknowledge that this falls within the realm of possibility. About to download the app so I can verify for myself...
