Caliper

The precision of a professional tool, right in your pocket.
Have you ever needed to measure something but didn't have a tape measure handy? Caliper turns your smartphone into a high-accuracy measuring tool by using a reference object to define scale in any photo.
Why Caliper?
Standard "AR Rulers" often struggle with lighting, flat surfaces, or distance. Caliper solves this by using a Reference Object of a known size (like a credit card, a coin, or an ID). Simply place the reference next to the object, snap a photo, and Caliper does the math.
HOW IT WORKS:
Place a Reference: Put a common item (Credit Card, Coin, A4 paper) in the same plane as the object you want to measure.
Capture: Take a photo from a straight-on angle.
Calibrate: Align the Caliper markers to your reference object.
Measure: Drag the measurement lines to any item in the photo to get instant, accurate dimensions.
KEY FEATURES:
Built-in Reference Library: Choose from common presets like USD coins, Credit Cards, or Standard Paper sizes.
Custom References: Use your own objects! Simply input the known width or height of any item to use it as a scale.
Sub-Pixel Precision: Use our magnifying lens to place markers with extreme accuracy.
Multiple Units: Switch instantly between Millimeters (mm), Centimeters (cm), Inches (in), and Feet (ft).
