Spirit Level vs LevelMaster

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.

LevelMaster turns your phone into a precision spirit level and angle meter, using the built-in motion sensor — no extra hardware needed. BUBBLE LEVEL • Circular bubble level for flat surfaces — lay the phone on a table, shelf or countertop • Bar bubble level for vertical surfaces — hold it against a wall, door frame or picture • Automatically switches between flat and vertical modes as you move the device ANGLE METER • Large protractor-style gauge with a live degree readout • "Set as 0°" lets you zero out any starting angle — handy for measuring a slope or a change in angle (e.g. a ramp or a roof) LEVEL ALERT • A confirming beep and a light vibration the instant the device becomes level • Turn the beep or vibration off independently in Settings CAMERA OVERLAY • See a level line through the camera while you hang a shelf, a frame or a piece of art • The line turns green the moment it's level CALIBRATION • Correct small sensor offsets against a known-level reference, per device MADE FOR EVERYONE • Light & dark themes with multiple accent colors • English and Japanese • Keep the screen on while measuring PRIVACY FIRST • Works fully offline. The camera is used only to overlay the level line — nothing is ever captured, saved, or sent anywhere. No account, no cloud, no tracking. Great for DIY projects, hanging furniture after a move, and checking a boat or dock is level while fishing. Note: readings are approximate and depend on your device's sensor. LevelMaster is intended for everyday DIY use, not for professional or regulatory measurements. Free, supported by ads.
