Spirit Level: Bubble & Angle

Turn your iPhone into a precise, easy-to-read spirit level. Pocket Level uses the built-in motion sensors to measure tilt, angle and slope in real time, with numbers so big you can read them at a glance. No clutter, no sign-up, and no ads getting in the way of your work. ▼ Main features - Bubble level vials: horizontal, vertical and a bull's-eye (round) view - Auto switching between horizontal and vertical mode as you rotate the phone - Digital angle readout in 0.1° steps, on both X and Y axes - Switch units: degrees (°), percent slope (%) or roof pitch (x:12) - Freeze the reading to lock the current value - 1-tap calibration to fine-tune accuracy on your own surface - Camera clinometer: live horizon line, crosshair and tilt angle - Haptic feedback, sound on/off, and a clean dark interface ▼ Free, and no ads Pocket Level is completely free to use, with no ads and no subscriptions in the released version. Measure, level and align as much as you like. ▼ Premium (one-time purchase) An optional one-time in-app purchase unlocks extra tools: zero the reference angle in the camera clinometer for relative measurement, add the percent slope and roof pitch units, and support future features. Buy once, keep it forever. ▼ Please note Readings are estimated from your device's sensors, so accuracy can vary by model. Use the 1-tap calibration on a known flat surface to adjust and get the most reliable results. Whether you're hanging a picture, checking a shelf, building furniture, mounting a TV, leveling an appliance or measuring a roof pitch, Pocket Level gives you a fast, reliable angle anywhere.
