Level & Measure Camera

Level & Measure Camera turns the sensor already in your phone into a spirit level you always have with you. Put the phone on a shelf to see whether it runs true, hold it against a picture frame to straighten it, or aim the camera at a wall and line the horizon up before you take the shot. No account, no sign-up, works completely offline. 🫧 A real bubble vial The classic glass vial tilts with your phone and the bubble floats to the high side, exactly like the level in a toolbox. Two centre marks show the tolerance: get the bubble between them and the reading is level. 🎯 Crosshair for flat surfaces Lay the phone down on a table, a shelf or a tripod plate and the crosshair shows both axes at once — front to back and left to right. Bring the dot into the centre ring and the whole surface is level, not just one edge. 📐 Degrees or percent slope Read the angle as degrees (12.3°) or as a percent slope (21.8%) — the unit builders, gardeners and roofers actually use. Switch at any time; saved measurements follow the setting. 📷 Camera with a true horizon The camera view puts a rule-of-thirds grid over the live picture plus a horizon line that stays level while the phone tilts. Line up the shot, then tap once to save a photo with the grid and the line burned in. Nothing is saved unless you tap. 📌 Hold the reading Press Hold and the number freezes, so you can take the phone off the beam, out of the cupboard or down from the ladder and still read the angle comfortably. 🔖 Save measurements with names Keep a short list of the angles that matter: kitchen shelf, garage ramp, picture frame. Tap one to rename it, swipe to delete it. The list lives on your phone and nowhere else. 🎚️ Calibration you control Every phone is a fraction of a degree off. Rest it on a surface you trust, tap Set as zero, and the app takes that as level from then on. One tap puts the factory zero back. 🔔 Tells you when it is level A short buzz the moment the reading reaches level, so you can watch the shelf instead of the screen. Add a tone if you like, or turn both off. 👋 Meet Lensy Lensy, the little lens carrying a spirit-level vial, greets you on the first start, explains why the camera permission is needed and cheers when you hit dead level. Friendly, never in the way. ♿ Made to be easy Large buttons, a big angle readout with steady digits, and a keep-screen-on setting so the display does not dim mid-measurement. Available in more than 30 languages, and you can change the language inside the app. 🔒 Private and offline Angles are read from the motion sensor on your device. The app has no account, no server and no internet requirement. The only Android permission it asks for is the camera, and only when you open the camera view — no microphone, no storage permission, no location. ✨ Free, with one optional upgrade Every feature above is free, supported by a small banner and an occasional full-screen ad. A one-time purchase removes ads forever; it is not a subscription. Level & Measure Camera is a household tool for shelves, frames, appliances, ramps and photographs. It is not a certified measuring instrument and should not be used where a calibrated level is required.
