Microscope is a handy utility app that utilizes your device rear facing camera, zoom lense, and macro focus mode in order to simulate a microscope effect on your screen. The app works great for those who are hard of seeing, or just for inspecting things from closer up.
Microscope features a variable zoom slider so you can get as close as you need to. It also allows you to freeze the image, or save the image to your sd card for later review. You can even share your saved images on social media.
