LevelMaster vs Camera Scale 簡単メジャー&距離測定

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.

Measure real-world lengths with your iPhone camera. No tape measure needed. ■ Two steps Put the crosshair on where you want to start, and tap Measure. Move your iPhone to the end point. That's it. The number updates live as you move, like pulling out a tape measure. ■ Two ways to measure [Target mode] Measure things you can't reach. A ceiling beam, wall to wall across a room, the gap where a piece of furniture has to fit. Requires an iPhone with a LiDAR scanner (Pro / Pro Max). [Device mode] Measures how far the iPhone itself moved. Touch it to one end, move it to the other. No depth sensor involved, so it works in a dark room and on glass or polished metal, where depth sensing struggles. ■ Steady aim Your hand shakes when you line up a point. The image is zoomed slightly, and the spare margin is used to cancel that shake. When your aim settles, the ring around the crosshair tightens — so you can see the right moment to tap. ■ Rangefinder When you're not measuring, the distance to whatever the crosshair points at is shown continuously. Distance to a wall, height of a ceiling, how far away something is. ■ Save the result When you're done, save a photo with the measurement line and the number drawn on top. Keep it as a note, or send it to someone as it is. ■ Good for • Checking whether furniture or an appliance will fit • Measuring a doorway before moving day • Sizing a shelf board or a curtain • Finding the distance to a wall or ceiling • Any time there's no tape measure around ■ Units Switch between centimeters and inches. The default follows your region. ■ Device support Target mode needs a LiDAR scanner (iPhone 12 Pro and later, Pro / Pro Max). On iPhones without LiDAR, Device mode still measures. Note: readings are approximate. For construction, trade, or anything where accuracy matters, use a real measuring tool.
