Level Tool turns your iPhone into eight measuring tools that run on the sensors already in your pocket. EIGHT TOOLS IN ONE APP - Bubble Level: two-axis spirit level for horizontal and vertical surfaces - Ruler: on-screen ruler in inches, centimeters and millimeters - Protractor: read angles and slopes through the camera - Stud Finder: sweep a wall and watch the magnetic field rise over screws and nails - Metal Detector: spot metal near your device with the magnetometer - Compass: heading and cardinal direction at a glance - AR Ruler: measure distances in 3D with the camera - Height Measure: measure height with augmented reality MADE FOR EVERYDAY JOBS - Hang pictures, shelves and mirrors straight - Check whether furniture, tables and appliances sit level - Read exact angles for cuts, ramps and installations - Carry a full set of measuring tools for DIY, carpentry and home improvement HOW IT WORKS - Every tool reads the sensors built into your device, so no extra hardware is needed - Measuring works without an internet connection and without an account - Switch between imperial and metric units whenever you like - Haptic feedback confirms every reading - Calibrate the bubble level and the stud finder in one tap GOOD TO KNOW Readings depend on your device's sensors and on how you hold it. Level Tool is made for everyday work around the house and the workshop, not for certified or safety-critical measurement. The AR tools need a device that supports ARKit and enough light for the camera.
