Bubble Level & Angle Finder

GenArt Level is the bubble level that feels like a real precision instrument: a smooth, sensitive bubble, big readable numbers, and a calibration that actually makes your phone accurate. Lay it on a shelf, stand it against a door frame, or set it on a roof. It tells you exactly how far off you are and which side to raise.

FOUR TOOLS IN ONE
• Surface level: a 2D bullseye with X/Y readouts for tables, appliances, floors, washing machines, RVs and camper trailers.
• Vial / plumb level: a classic spirit-level vial. Stand the phone on any edge and the display rotates to stay readable, so it works for shelves, picture frames, TVs, cabinets, door jambs and posts.
• Angle finder (inclinometer): measure any slope from 0 to 90° with the back of the phone or its long edge. Use Zero to measure relative to any angle, which is ideal for saw bevels, miter cuts and matching existing angles.
• Roof pitch: rise in 12 (6/12, 8/12…), plus degrees and percent grade, for roofing, solar panels, ramps and drainage.

ACCURATE, AND STAYS ACCURATE
• Flip calibration needs no level surface: take a reading, turn the phone around, take another. Your phone's sensor error is cancelled out.
• One calibration corrects every tool in every orientation, flat or on edge.
• Adaptive smoothing gives a rock-steady reading when still and fast response when moving, with no jitter and no lag.
• Readouts to 0.1° or 0.01°, with an adjustable level tolerance from ±0.1° to ±1°.
• Adjustable bubble sensitivity (±2°, ±10° or ±30° full scale), so a tenth of a degree is visible on the bubble.

LEVEL WITHOUT LOOKING
• A satisfying click and tone the moment you hit level.
• Guidance beeps and vibration pulses that speed up as you get closer to level, like a parking sensor. Perfect when the phone is on a high shelf or behind an appliance.
• Full vibration control: on/off, strength, vibrate on level, guidance pulses and button taps.
• Choose your level sound (Tock, Chime or Bubble) and its volume. Sounds follow your phone's silent mode.

MADE FOR REAL WORK
• Hold freezes any reading so you can read it after measuring in an awkward spot.
• Auto-hold locks the angle by itself once the phone is still.
• Units: degrees, percent slope, inches per foot and mm per meter. All free.
• Tells you which side to raise, so you're not guessing.
• Keep-screen-on while measuring.
• Beautiful dark and light themes, large high-contrast numbers.

RESPECTS YOU
• No permissions to grant: no camera, no location, no storage.
• Works fully offline.
• Never shows a pop-up ad while you measure. One optional small purchase removes ads for good, with no subscription.

Perfect for DIY, carpentry, woodworking, construction, hanging pictures and TVs, installing shelves and cabinets, leveling an RV, camper or trailer, washing machines and fridges, pool tables, 3D-printer beds, tripods, telescopes, drum kits, aquariums, roofs and solar panels.
