What is Google Bubble Level?

Google bubble level is an accessible built-in tool that is dedicated to measuring the levelness of a surface on your phone. This feature uses your phone’s accelerometer sensor to determine if the object is horizontally or vertically aligned or not.

Using the Google bubble level is a convenient and handy way to find out how level a surface is. The tool requires your phone’s edge to be flat, as it uses this edge as the base to measure the surface’s levelness. This means that you can either place your phone flat on its back or use it in an upright position to get what you’re looking for.

How to Use Google Bubble Level

Google bubble level can be accessed easily through your Android’s browser. All you have to do is type in ‘bubble level’ in the search bar and the Google bubble level will appear at the top of the search results.

Even more, if you don’t feel like typing it out, you can also speak out the words to Google Assistant and bubble level will pop up in the search results in an instant. Users even have the options to make this tool a widget on their phones for quick access.

If you’re an Apple user, you may also use Safari to access the Google bubble level. Although you should already have a Compass app that incorporates a level measurement tool to save you an extra step.

Once you’ve accessed the tool, begin by aligning your phone on the surface you wish to check, either horizontally or vertically. Make sure that there’s no bump that’s stopping your phone from being flat on the surface. The bubble on the screen will reveal the levelness of the surface.

If the bubble is in the center of the guidelines and the reading shows zero degrees, it is an indicator that the surface is level. However, if the degrees indicate any deviation from zero, either negative or positive, it means that the surface is tilted or not entirely level.

It’s also important to ensure that your phone’s sensors are properly calibrated for accurate measurements. Any uneven surface, such as the protrusions of your camera or side buttons, can result in incorrect readings. Hence, we recommend that you utilize this tool only for minor leveling tasks, otherwise, the physical spirit level should be used for serious leveling work.
