Read full descriptionHide full description
This app allows user to take a picture of areas written in red and make only the red text less visible. After taking a picture with the camera, the app saves two images: the original image and an image with the red text less visible. Even if user don't have a red transparent sheet, user can still memorize and study by hiding the parts highlighted in red pen.
