Getting older or not, we all can use a little help sometimes reading tiny print or microscopic part numbers on various devices. Of course there is an app for that!
Two of the best (and free) are Magnifying Glass with Light for Apple gadgets and Magnificent Magnifier HD for Android users. Each magnifying app uses your smartphone’s camera to enlarge wherever you point. It can also fire up your phone camera's flash/flashlight, which can help if you are trying to read in a poorly lit area. Kids will also love these apps for looking at insects, rocks and other objects in nature.
