User reviews

The app needs work but it works for distances of 15 feet roughly

The app works but the range of footage it can measure before losing tracking kinda sucks but it has free demo without giving away your credit card details so it’s will be worth a buy if developer fixes the range issues.

Not accurate

Not only not accurate, but also mistakes vertical with horizontal axis most of the time.

It does not work

Impossible to accurately measure anything

Forces off the flashlight

Don't really like that this app force turns off the flashlight

Amazing little app

Simple and works exactly as intended, doesn’t ask for personal data, no ads, free, what else can we ask for :)

FAQ

What can I measure with this app?

You can measure small objects directly on your device's screen for simple and precise measurements. For larger items or distances, you can use augmented reality to place a virtual measuring tape on surfaces like walls, tables, or floors. Additionally, the app allows you to print a ruler for physical measurements.

How does the augmented reality measurement work?

The app utilizes ARKit to enable augmented reality measurements. You can place a virtual measuring tape onto vertical or horizontal surfaces in your environment, allowing you to measure distances in the real world through your device's camera.

Is this app free to use?

Yes, this app is completely free to use. It does not feature any advertisements, in-app purchases, or user tracking, providing a clean and uninterrupted measurement experience.

How accurate is the printed ruler?

The accuracy of the printed ruler depends on your printer's calibration and the printing process. It is recommended to check the printed ruler's result against the on-screen ruler provided by the app to ensure its accuracy for your needs.

What devices is this app compatible with?

The app is built with ARKit, which typically requires devices that support ARKit for the augmented reality features. For the AirPrint functionality, you will need a compatible printer. Specific device compatibility details are usually found in the app store listing.
