Level - Simple Bubble Level

Advance Integrated Tech LAB

About this app

Level is a one-screen spirit level that does one job perfectly and respects you completely.

It requests zero permissions and has no internet access, so nothing you do in it can leave your phone — the app physically cannot collect or transmit anything.

WHY THIS ONE
• Zero permissions — the app cannot access the internet, your files, your location, or anything else
• No third-party code: no analytics, no crash reporting, no SDKs
• Tiny: the whole app is smaller than a single photo

WHAT IT DOES
• Two-axis bubble level with live degree readouts (X and Y, to 0.1°)
• The bubble moves toward the high side, exactly like a real vial
• Turns green with a gentle haptic tick the instant you hit level
• Tap to freeze the reading — handy when your hands are full
• Long-press to calibrate: any trusted surface becomes your 0.0°, remembered forever
• Screen stays on while you work

PERFECT FOR
Hanging pictures and shelves, leveling appliances, workbenches, camper vans and RVs, 3D-printer beds, turntables, aquariums — anywhere "close enough" isn't good enough.

PRIVATE BY DESIGN
A clean tool with nothing hidden inside. Scroll down and check the permission list on this page — it's empty. Calibration offsets are stored only on your device. That's the product.
