Review Update. Waste of money

Updating in my last review I have to say its a pretty good app over all, really good results! It does crash when using live images like mentioned by developer and a fix is on its way. Maybe the ability for more than 70 images? Will consider it for our acquisition pipeline.

Wonderful reaults easy to use

Ive been enjoying this app - you can see my experiments on sketchfab under my account tmixer. I would like more detail in my models, allowance for manual photo capture and more photos as well as a manual crop mode. I hope AR mode keeps developing because its great for scenes. Good work devs and thank you for a one time purchase model. I tell everyone about this app in my creative circles. Cheers

Edit: thanks for the reply devs. I do realize you can import your own photos for processing but thank you for the tip. What I was referring to was the ability for manual control of the shutter as well as the auto shooting it does currently. Thanks for considering this. Maybe a pro option for would allow higher resolution models and more than 70 photos.

Best to you all

Thanks for the review! We're currently updating our queue to drastically reduce wait times, but we'll be adding editing shortly. You can actually import images. Click on the top left button to import any image from your camera roll. Glad you like the pricing. We're trying to keep it affordable.

BEST 3D Scan App for iPhone

I had to write a review for this app because it’s the ONLY one that actually works. I’ve tried all of them including ones that use the depth sensors.
I needed something that would create a 3D model of miniature objects and this one worked flawlessly. I found the easiest way to do it was to use the photo feature and have the app stitch the pictures together. I used a turntable and tripod (with good lighting) to take the pictures, uploaded them to the app and let it do its thing.
After the scan was done I just emailed it to myself and then opened in one of my desktop programs for modifications.
Everything is super easy and I finally have an exact replica of what I wanted to create!
