I added that to the todo-list. About the images you can actully have 2 for each exercise. I have been thinking about it and I decided not to have gui for it. The reason, you have to put the image on the phone. And if you have a gui you first need to put them on the phone then open the program and add the images. Why not just name them "exercisename1.png" or "exercisename2.png" and put them in the right place directly(wich for now is MyDocs)? I know this maybe is not optimal but for now it have to be like this.

Edit: It now reads the proximity sensor so it won't register a shake while being in the pocket.
