Hanging a picture, putting up a shelf, checking a table or lining up a shelf bracket — the level tool shows a clear bubble and a live angle in one glance.

A machined vial sits at the center of the screen. Tilt the phone and the bubble drifts the way it does on a real spirit level. When the surface comes flat the bubble locks green and the phone can buzz to confirm it, so you do not have to squint at tiny lines.

AROUND THE HOUSE AND THE WORKSHOP
Hanging pictures and mirrors straight • mounting shelves, TVs and curtain rails • checking floors, worktops and table legs • DIY, woodworking and carpentry • lining up a washing machine or fridge so it stops rocking • leveling a tripod, a camera or a projector • checking a caravan or camper before you settle in for the night

The accelerometer already in your phone does the work, so this leveling tool needs no special permissions and works anywhere, even with no signal.

SPIRIT LEVEL FOR PHONE — HOW ACCURATE IS IT?
Readings come from your phone's built-in accelerometer, so what you see depends on that sensor and on how flat the back of your phone or its case really is. Calibrating on a surface you trust helps a lot. It is a handy digital spirit level for home jobs, not a certified instrument: for structural, safety-critical or trade work, use a physical spirit level.

ANGLE FINDER AND SLOPE METER
Beyond simply checking flat, the angle finder mode gives you a live degree reading in portrait or landscape. Useful for setting the angle on a saw guide, checking the slope of a roof panel, aligning a ramp, or confirming the tilt of a display mount. Switch to percentage slope for applications where gradient is measured that way — drainage, driveways, accessibility ramps.

WHO KEEPS A BUBBLE LEVEL APP
DIYers who need a level tool for weekend projects and do not want to hunt for the spirit level in the garage. Renters hanging pictures who cannot mark walls and need precision without commitment. Photographers and videographers levelling a tripod or gimbal in the field. Camper and motorhome owners checking they are parked level before cooking. Tradespeople who want a backup angle finder on their phone for quick site checks.
