App broken

I tried several times across a span of about a week to get it to work but it never even accepted the picture. I took pictures beforehand and uploaded them and I used the app to take the pictures but the result was the same. It refused to start making the model saying every time there was an error. Sad cause it looked like it would be a very nice app to use

Sorry to hear about your difficulty uploading images. We just revamped the app this week and improved the upload process. Our uploads are now 5X smaller as well. The AR Scanning is also more robust. Just make sure to scan items with a lot of detail in good lighting. Thanks!

trnio is magic, I was able to scan an object and use it for a 3d printing project. Huge time saving, Trnio was a life saver

Amazing, Hi-Resolution, 3D Models, So easy to use!

As the first reviewer of this app, I can say that I am blown away by the quality of 3D models that this app can produce. It does take some getting used to at firs, but if you give it a few tries you will be making photorealistic 3D models in minutes When using this app, it’s best to keep in mind the different conditions that help you get a great scan. Lighting should be bright, and it’s best to scan at the same distance around an object. The app is great for capturing memories in 3D (e.g. 3D portraits of friends and family) and also capturing objects for other fun things (3D printing and game development.) I highly recommended it!
