Take a new photo or pick a photo from your photo library and then count objects on it by tapping them. Save screenshots and/or share them via email or social networks. Use the Line tool when you need to mark a sequence of objects with equal distances between them (note: this doesn't work well with object viewed in perspective). Use the Multiplication tool to count objects positioned in 'rows' and 'columns'.
