Photo Measures Lite allows users to mark up photos with dimensions and notes, then save or share them with others. The concept is so simple that the app doesn’t seem worth mentioning, until you try to imagine how else you would accomplish the same task without the app. For example, let’s say you wanted to describe to your deck builder how the back of the property slopes down to the patio. You’d probably send measurements, notes, and instructions in an email and attach a photo, and hope the recipient can piece the information together. Photo Measures Lite combines all the info — visual, textual, and numerical — into a single image, leaving little room for misunderstanding.
