### 3/5 — doesnt work PRO

*2025-01-13*

in pro version see alert limit size - buy pro

Best regards, i4 Support

### 1/5 — Need to pay to try out own models

*2022-04-24*

Pretty much any model you upload - once you figure out how to do that as there is no “import model” feature will be above whatever file size limit they set.
Besides the app is not user friendly at all.

### 1/5 — Can’t import any Models for 3D AR Viewing

*2021-10-01*

I just purchases this app so I can import my DWG / CAD 3D models, so that I can view our machinery to scale, in real time, in order to show a client what the finished product would look like on their factory floor. 

There is now way to upload your files or access them from any source. Seems like waste of $4

**Developer response:** Hello Caejun,
we are sorry you're having issues with the app.
In order to load your own files, please copy your files to "On My iPhone / i4 Review / i4AugmentedReview". Please remember that we only support FBX and OBJ files.
Best regards,
i4 Support

### 1/5 — inservibile

*2021-06-12*

Non è possibile aprire i file locali. App inservibile. Soldi buttati.

**Developer response:** Hello Spaggio80,
I am soooo sorry for the really late reply - I must have overlooked your feedback.
To load your own files you must copy them to the directory “On My iPhone / i4 Review / i4AugmentedReview”. Please remember that we only support FBX and OBJ files.  
Best regards, i4 Support

### 5/5 — Super AR Viewer

*2020-02-20*

Super Tool um ein OBJ in AR anzuzeigen.

### 1/5 — Application qui ne marche pas

*2019-11-29*

Après avoir importé mon fichier obj dans l’application, impossible de l’ouvrir. Quelques secondes de chargement, puis l’application plante et je me retrouve sur le menu principal de l’iPhone. 
Impossible de se faire rembourser par Apple alors que l’application ne marche pas.
