Measurement tools
More than a basic bubble level meter
Built for people searching for a bubble level app, inclinometer or practical level tool while still wanting calibration, saved profiles and professional workflows.
Inclination and slope
Read pitch and roll using degrees, percentage, mm/m or in/ft depending on the job.
Two-point calibration
A guided calibration flow is designed to reduce device-sensor bias and improve repeatability.
Profiles and surfaces
Organize surfaces, projects and calibration references for jobs that need different setups.
Professional reports
Save measurements and prepare reports so results do not have to be copied manually.
Voice guidance
Voice commands and spoken feedback help when both hands are occupied during a measurement.
Privacy by design

Core measurements and profiles stay on the device. Online services are separated and used only for specific features such as security, purchases, optional backup and rewarded ads when enabled.
- No BubbleLevel account is required to use the level.
- Core measurements and profiles are processed and stored locally.
- Optional, user-authorized Google Drive backup.
- Play Integrity and the Notary service are separated to protect the app and premium features.

BubbleLevel questions
Is BubbleLevel a real spirit level app?
Yes. It uses available Android device sensors to show level, tilt and orientation. Final accuracy depends on the phone's sensor quality and calibration.
Can it work as an inclinometer?
Yes. BubbleLevel reports pitch and roll and supports multiple units for slope and inclination.
Does the bubble level app need Internet access to measure?
Core measurements are local. Network access is used only for separate functions such as integrity checks, purchases, optional Google Drive sync or rewarded ads when enabled.
Can I use BubbleLevel online in a browser?
BubbleLevel is designed as an Android app rather than a browser-based online level. This website provides product information, support and legal documentation.
