Bubble Level & Digital Ruler

Hang a picture frame straight. Check whether a shelf actually sits level. Measure something small when there's no tape measure in reach. Bubble Level & Digital Ruler keeps a spirit level and a screen ruler in your pocket, so a two-minute job doesn't mean digging out the toolbox. The level reads your phone's accelerometer in real time and shows tilt as a moving bubble plus exact X and Y angles. The ruler turns your screen into a measuring scale in centimetres or inches. 🔧 BUBBLE LEVEL & SPIRIT LEVEL Three levels in one screen, so you can check almost any surface: • Bullseye level: A round vial for flat surfaces like tables, shelves and floors • Horizontal tube: A classic spirit level vial for left-to-right alignment • Vertical tube: For door frames, posts and anything upright The bubble moves the way a real one does: it drifts toward the high side and settles smoothly instead of twitching. Angles update live in degrees, and the readout holds steady at 0.0° once a surface is level, so you're not squinting at a flickering number. WHAT PEOPLE USE IT FOR • Hanging frames, mirrors, shelves and wall art • Levelling washing machines, fridges, desks and furniture • Carpentry, woodworking and DIY around the house • Checking a slope, a ramp, or a surface angle on site • Quick alignment checks when a proper level isn't nearby LEVEL FEATURES ✔ Live X and Y angle readout in degrees ✔ Smooth, damped bubble movement — no jitter ✔ One-tap zero calibration: set your current surface as 0° ✔ Screen lock to freeze a reading while you look at it ✔ Beep alert the moment an axis hits level (can be turned off) ✔ Screen stays awake while you measure 📏 DIGITAL RULER No tape measure? Lay a small object on the screen and drag the two guides to its edges. The measurement updates as you drag. RULER FEATURES ✔ Switch between centimetres and inches - your choice is remembered ✔ Guides snap onto exact tick marks for clean readings ✔ Live measurement shown in large, readable numbers ✔ Millimetre marks in cm mode, 1/8" marks in inch mode Note: the ruler measures objects up to the length of your screen, and screen readings vary slightly between phone models. Treat it as a handy estimate, not a replacement for a calibrated tape. ⚡ FAST AND LIGHT • Opens instantly - no splash screens, no waiting • Small download, light on storage • The level and ruler work without an internet connection • Clean layout with nothing to learn 🎨 MAKE IT YOURS • Light and dark mode • Turn the level beep on or off • Privacy Policy and Terms available inside the app 🛠 WHO IT'S FOR DIYers and homeowners, carpenters and woodworkers, decorators and interior designers, students, and anyone who has ever eyeballed a shelf and regretted it. A NOTE ON ACCURACY This app uses the sensors already in your phone. It's genuinely useful for everyday levelling and quick checks, and the calibration button lets you zero it against a surface you trust. For structural, engineering or safety-critical work, use a calibrated tool. Download Bubble Level & Digital Ruler and stop guessing whether it's straight.
