I made this app as a creative project assignment for my forensics class. This app calculates the angle of impact of a blood drop using the drop’s length, width, and distance from the area of convergence (where all the blood paths intersect, making it the origin of the blood). The app also finds the origin's distance from the wall (or the surface the blood drop is on). With this information, you can make a 3-d map of where each blood drop came from, and get a better picture of what happened at the crime scene.

I had the idea for this app during the blood unit, because we were working on a project where we had to map an actual (pretend) crime scene. The image in the [?] menu is an actual photo from said crime scene. My group was able to use this app to get the angle and distance from surface calculations without having to do the trigonometry for all the calculations.
