Downloaded, opened, and problems

I have very little knowledge of this app other than what is said in the other reviews. I wanted to test it and did. 3 out of 5 stars bc when I went to measure a surface, it did not allow me to pick the right point. Apps should work right out of the Store.

FAQ

What can I measure with this app?

You can measure linear sizes in centimeters and inches, distances using augmented reality, angles, area, perimeter, volume of 3D objects, and the length/area of paths. It also includes an on-screen ruler for measuring small objects directly on your smartphone's screen.

How does the Augmented Reality (AR) feature work?

The AR feature allows you to accurately measure distances from your device's camera to points on a detected 3D plane. This enables you to measure larger objects or spaces that wouldn't fit on your screen.

Is this app free to use?

Yes, the app is free to use. However, it does display advertisements to support its development and maintenance.

Can I save my measurements?

Yes, the app allows you to save your measurements. This is useful for keeping track of dimensions for projects or for future reference.

What devices is this app compatible with?

While specific compatibility details are not provided, AR features typically require devices that support ARKit (for iOS) or ARCore (for Android). The on-screen ruler functionality should be broadly compatible with most smartphones.
