Android users who use Pixel 2, Galaxy S9, and the G7 ThinQ will now be able to use the Google Measure App. This is because Android 7 and upwards supports the company’s ARCore standard. The project was previously known as Project Tango which involved specialised cameras and sensors.
The measure app is a augmented reality app that you can use to measure things. The Google Page gives the following info:
Move your phone around the space to find flat surfaces such as tabletops or the floor. Then drag a length tool or height tool into the scene, and adjust it to the right size. Tap the camera icon to snap a photo for later, or tap the trash icon to start a new measurement.
Earlier at the WWDC event, Apple had announced a similar Measure App which will come along with iOS 12. It also works by pointing the phone’s camera to measure objects.
