Organize, Compare and Measure Before & After Photos

Before & After Photo Viewer iPhone App

Layer Lapse – Before & After Viewer - Adam Hammons

Layer Lapse is used to compare and categorize photos to easily see changes or differences. You are also able to measure pixel differences and advance through scenes of overlapping and semi-transparent photos for a time-lapse effect of layers.

This method of comparing photos gives you the ability to quickly detect the smallest difference and allows for easy organization so you can keep your photos ready for comparisons in the future and with others.

FYI: “Layer Lapse is like having a perfect photographic memory to know in an instant what is different but with psychic mindreading telepathy as you can compare your memory with others’ memories and even having bionic eyesight enabling you to measure pixels like a robot. It’s an app of super powers.”
