Smart Distance is an app that lets you calculate long distances on your Android. All you need to do is point your device's camera at a distant object and the app will automatically calculate the distance from here to there.
Using Smart Distance is very simple: enter the height of the object whose distance you want to measure, and then adjust the green lines. By doing this, you can immediately find out the distance between your camera and said object. Here are some easy references: the average person's height is 1,70 meters, a bus is around 3 meters. and a door is normally 2.
The app's pro version lets you access some additional features, like measuring the distance from an object based on its width or zooming in and out with the camera.
Smart Distance is one of those apps that seems almost magical. Luckily, there's nothing magical about it, it's just math.
