  • Awesome! The recognition rate of this app is much better than any other camera-based OMR apps. I recommend this app for parents or tutors who teach their children or students at home. Two thumbs up!!!

    Very good application, this is what I needed. Now I'm enjoying my time with my family instead of grading papers.

  • It is a very good application to adjust the number of questions and number of choices made freely. As a side note, the paper and the camera (optical axis) is not perpendicular to the time of reading, you tend to read miss occurs. Everything else is higher reading accuracy. You can also recognized with a ballpoint pen. Because it was very polite also the developer's support for an inquiry when there is a problem, I think that he will go in the future be more and more improvement.

    The developer has been very helpful and responsive to my questions and calls for help. Hope to continue the working relationship as this app continues to grow.
