The Smart Measure app.

The next entry in the list of best measuring apps is The Smart Measure app. It is a measuring app that mostly uses the main camera of your smartphone. The camera then lets the app gauge the distance of an object and the height of that object. To use this app, all you need to do is press the distance button. The app will then try to guesstimate the distance between you and the target object. If you want the height of the target object, all you need to do is to point at the bottom, tap the height button, and tap once more at the top.
