Precisely what these old eyes need!
I buy something from China, a micro-sized drone, say, and the instructions look like fly-specs. I cant read them. Thanks to this wonderful app, I can enlarge those instructions so that they are readily legible. Except of course that they were produced by some combination of Google Translate and a dart board. So I still cant read them.
