Good interface, reading image quality difficult to maintain – VisionAssist Review

I like the concept, and this app will be useful in some circumstances. I tried the app first on an iPhone 4, found the best magnification level for me, and switched to white on black. It was usable, but took a bit of care to move the phone over the text and remain in focus as I moved. I tried it on an iPad 2 and it was not as good because the image was less clear and harder to maintain. The smart text feature with magnification turned up to where I needed it wasn't helpful. The image freezes for almost a second at a time as it processes the image to enhance text, so moving the magnification along over text was jerky. The enhancement was very subtle, and did not have a white on black mode. Using the light on the iPhone 4 was useful. In a darkened situation where I need to read something, it would be quite useful. Having just tried a Ruby portable magnifier today, the Ruby was by far much easier to read. The device was designed for that purpose. But at $550, it or something like it might be out of price range, in which case this app could be a fair substitute. I know this app will get more useful as the optics in these devices improve.
