What is the best magnifying glass app?

Hello, I tried a few free magnifying glass apps for my 6s plus. When zoomed in, the images and letters were fuzzy. What app do you recommend?

Sorry I meant using the iphone 6s plus as a magnifying glass.

You are limited by the optics in the phone, so I am unsure as to what you expect?
