Poor OCR
I had an application that had a list of data that I needed to get converted to text. The app didnt have any way to export it and nothing was selectable on the screen. So I scrolled the screen and took screen shots, only about 10 of them, no big deal. I then cropped out everything except for the text. Should be a VERY easy conversion since it is nice and crips with absolutely no garbage in the image. I was able to achieve about 50% accuracy. This is pitiful. I found another application that was able to do a 98% conversion. I was quite disappointed with the application.
