In this example, I've scanned my ukulele. I start by putting my object (ukulele) within the frame, and just tapping anywhere on the screen to capture it.
#2, the capture. Scan Thing converted my physical object into a digital one. It automatically even removed all background content for me. Now, I can use this digital copy of my ukulele for whatever I want (social media, Photoshop, wallpapers).
#3, the final product. P.S. you'll note two of the tuners (on the top) didn't make the final cut. This was mostly because of the lighting in my room + the similarity in colour between them and the carpet... but that being said, voilà!
This was just one example of many. Scan Thing lets you scan objects, people, animals, plants, art, food... virtually anything. But there's more.
Let me quickly go through the options on the bottom.
