Precision Toolkit: Level App for iPhone and iPad
Precision Toolkit is a practical measuring app for iPhone and iPad that helps you check alignment, measure tilt, find direction, detect magnetic field changes, and make quick everyday measurements.
Use it for home improvement, DIY projects, hanging pictures, aligning furniture, checking slopes, measuring surfaces, and quick field checks.
Tools included
Eight measuring tools in one iPhone app.
Start with a bubble level, then move into surface tilt, camera alignment, augmented reality measurement, direction, magnetic field checks, vertical alignment, and vibration.
Measure roll and pitch angles.
Measure roll and pitch angles on flat surfaces. Use it for shelves, tables, equipment, furniture, and quick slope checks.
Find direction and heading.
Find direction, heading, coordinates, and elevation using your device sensors.
Detect magnetic field changes.
Detect magnetic field changes around your iPhone using the built-in magnetometer.
Align objects with camera guides.
Use camera guide lines to help align frames, shelves, furniture, wall decor, and other objects.
Measure with augmented reality.
Measure distance, size, and area using your device camera and augmented reality tools.
Check vertical alignment.
Check vertical alignment and tilt direction with a clear plumb line view.
Measure movement and vibration.
Measure movement and vibration with live sensor data, waveform display, and axis readings.
Built for simple everyday use
Clean controls for quick measuring jobs.
Precision Toolkit includes calibration support, lock mode, sound and haptic feedback, flashlight control, a clean dark interface, and support for iPhone and iPad.
It is built for fast checks around the home, small DIY jobs, field setup, and moments when you want a practical measuring tool already on your device.
Open the tool you need
Choose level, surface, compass, detector, laser, AR ruler, plumb line, or vibration.
Calibrate for the situation
Use calibration and lock mode when you want a stable reference during a task.
Measure and adjust
Read the live values, align the object, and verify the result before you finish.
Measurement note
Precision Toolkit uses device sensors, camera input, calibration, and environmental conditions to estimate measurements. For critical construction, engineering, safety, or professional work, always verify results with dedicated professional measuring equipment.
