Bull's Eye Level — Place your phone flat on any surface for a 360° bubble level. The bubble moves smoothly to show exactly how far off-level you are, with a satisfying green glow when perfectly flat.

Tube Level — Two precision tube levels show tilt on both axes. Perfect for checking shelves, tables, and countertops. Graduation marks help you see even the smallest tilt.
