Whoa! this is a fantastic app. Yes, it needs instructions and the developer says they are coming. (he responded right away to my email) This is by far the most accurate clone app (trust me I have them all) you simply use your finger to go around the shape (any shape) you want to clone in or out (most cloning programs have a fixed shape). Once that jagged white line around the area you want to clone is complete, you simply press and hold your finger on the that cut out you just made and drag it to the area you want to replace or be replaced. So, you can choose to clone something in the object you outline or you can choose to clone that area some place else in the image.......very simple and the people who gave this such a bad review just didnt take time to figure it out. Of course, the app needs (and will have instructions) and because it doesnt it would only get 4 stars from me but I am giving it 5 becaues the other reviews are so unfair. I am a professional photograhper and cloning is a huge part of my world. Trust me, this app does work (apple obviously tests and approves all apps) I have paid far more for computer programs and plug ins that dont work near as well partly due to the touch screen capability of the IPAD.....Bravo to developers like this
