Magniband is simple, fun and handy. It fits iPhones 4 to X as well as smartphones with similar dimensions.
Magniband offers a 4 x magnification when held 1 inch away from the subject.
To use, simply stretch over your phone and align, then hold your phone roughly 1 inch away from what you want to take a photo of and wait for your phone to focus. Two bands means 8 x magnification!
