### 1/5 — Scans won’t export

*2022-11-16, version 3.40*

I paid for this app thinking I paid to scan and export items. 

Trnio is not a listed subscription on my apple account and I was not prompted in-app to make any additional purchases for added benefits such as exports. 

Basically I don’t know if it’s a file prep isssue on my end or if I payed just to scan objects and look at them on my phone 🤷🏽‍♀️  When I go to export the file it takes a long time to load ( load bar in file export window) on my student issued computer and then never loads. I get a message saying the file cannot be used. I’ve tried all export file options in order to pull up in rhino with no avail.

**Developer response:** Thanks for chatting the other day, and for updating us on your solution. As discussed, Trnio exports all OBJ's as ZIP files.  When exporting, you'll also notice that the file type states .zip.  To import an OBJ into Rhino, the zip file must first be unzipped into a folder. After that, Rhino should be able to import our OBJ files.  

To the readers, the issue was with file preparation, and not an issue with the Trnio app.  If you have questions about importing into other programs, feel free to email feedback@trnio.com or message us on social. Thanks.

### 3/5 — Object Capture API please

*2022-01-09, version 3.35*

When I first got this app over a year ago it was fine compared to the competition and $5 for unlimited scans you can’t complain too much. Not that Apple Object Capture has come out it has rendered whatever algorithm Trnio uses completely useless. I have run the same photo set through Trnio, PhotoCatch on my Mac Mini M1, and an app I won’t name that uses Object Capture API. If Trnio even produces a result it’s not even close to being as good as Object Capture. Object capture will also use a turntable without any special background. Trnio is like most other photogrammetry programs and won’t do a turntable unless you give a solid black background with ring lights in a dark room. If Trnio could switch to the Object Capture API the app would be perfect

**Developer response:** Thanks for the feedback.  Trnio currently does not support your specific turntable use case.  We will be updating the app algorithms shortly to support LiDar-photo fusion capture (not available in object capture) and turntable mode.  Thanks!

### 1/5 — Does not work

*2021-12-22, version 3.34*

Tried multiple time with multiple things and no scan was usable, but every scan was hilarious because of how deformed it came out as. Was contacted by app developers and told to use the video I already used and didn’t get any better results. Other apps are superior to this one so I will use those instead of this expensive garbage.

### 5/5 — Size of object issue?

*2021-11-23, version 3.34*

I subscribed this app. This app is the great 3D scan through mobile phone. But I tried 3D print the my scanned model that is not work. I exported stl file and obj file these model size are way way small compare with actual model. How can I print original size? Thanks for replying back. But that was not enough for my curiosity. I understand that resize the object by mesh mixer or similar tools. But point is copying exact original size without using tools. Thanks again.

**Developer response:** You’ll have to scale the model In Meshmixer or something similar. Here’s an article on how to print a Trnio model. Hope it helps.

### 5/5 — Great

*2021-10-03, version 3.34*

The scans are really good and works most of the time But sometimes when scanning surfaces or rooms the auto masking cuts out alot of the scan. Would be cool if there was an option for that, maybe manual cutting would be cool. Also hoping sometime in the future this would allow more than 80 photos. Best phone scanner tho, and could have better results than those professional scanners sometimes.

### 3/5 — A piano

*2021-08-11, version 3.31*

If I could control when the app takes a picture, I could create a better model. It seems to take only when the camera is moving.

### 3/5 — Decent but great

*2021-06-26, version 3.31*

It does it’s job when it comes to photogrammetry. Even though I provide plenty of photos (30) it came out not as good as I hoped it would there’s promise that with trnio 2 or an update it could be better. I have plenty of reference pictures with more than enough points for it get an idea and recognize what I’m trying to a 3d model out of. I sincerely hope they improve it because as I said there’s promise. Also the capability of more than 80 pics because I have so many pictures

### 4/5 — It’s great for 3d printing

*2021-06-24, version 3.31*

I would have given it five stars but it took about 8 scans to get a good looking one it’s probably my technique but some scans don’t give clean results just keep trying and you’ll eventually get a good one

### 4/5 — Good

*2021-05-06, version 3.31*

This app is very useful, but it is still laggy and doesn’t always work. Im still learning how to use it correctly but I like it.

### 5/5 — What an absolute joy

*2021-04-22, version 3.30*

This app is absolutely incredible. I am astonished at the fidelity and speed. The workflow is fast, clean, and really enjoyable. I think this is a hidden gem. I am the head of my colleges 3D lab and i will be implementing this with all of our students. Would love to work with this company.
