If you're a detective looking for clues, one essential tool of trade is a magnifying glass. It helps you spot things you might otherwise miss.
If you aren't a detective, a magnifying glass is still something great to have around. You never know when you'll need to read tiny print on a document, minuscule instructions in a cook book, microscopic writing on a computer part or some equally inconvenient text.
Unfortunately, you might not have a magnifying glass just lying around. However, you probably do have a smartphone within arm's reach.
Turning it into a magnifying glass just takes the right app. I recommend the Magnifying Glass with Light for Apple gadgets and Magnificent Magnifier HD for Android users.
These magnifying apps use your smartphone's camera to enlarge whatever you point the mat. They can also fire up your phone camera's flash, which can help if you're trying to read in a poorly lit area.
No more squinting at menus or holding labels at arm's length. Now you can read fine print without your glasses and see things clearly in dim light.
