## What is Bubble Level?

Bubble Level - Calibrated turns your iPhone into a practical, accurate bubble level for everyday measuring, alignment, and leveling.

Most phones do not sit perfectly flat. Cases, raised camera lens bumps, uneven backs, and different phone shapes can all affect level readings. This tool is designed with proper calibration so you can account for real-world phone surfaces and get more reliable measurements.

Use it to check whether a surface is level, measure angles, align objects, or quickly verify slope. It is useful for hanging shelves, setting up furniture, aligning picture frames, checking tables, DIY projects, and quick household measurements.

Features:

- Bubble level for horizontal and vertical surfaces
- Proper calibration for phones with cases and camera bumps
- Helps account for uneven phone backs and raised lens areas
- Angle and slope measurement
- Clean, easy-to-read display
- Fast launch for quick checks
- Useful for home projects, DIY, furniture setup, construction, and alignment

A phone level should work with the phone you actually use — case, camera bump, and all.
