Terms of use

Using the tool
Bubble Level Online is a free browser utility that estimates tilt from your device’s motion sensor. You may use it for everyday checking tasks such as levelling a shelf, frame or tabletop. It is not a certified measuring instrument and must not be relied on for construction, safety or any work where an incorrect reading could cause harm. Confirm critical measurements with an appropriate calibrated tool.

The site and the tool are provided “as is”, without warranties of any kind. Readings depend on your device, browser, case and placement, and the tool may be unavailable or produce errors. We do not promise any particular accuracy, and we are not liable for decisions made on the basis of a reading.
