### 1/5 — Repeatedly won’t access images

*2025-10-19*

I got charged for this app, but it will not open the images folder that I need to get into to create my stereo images. It opens other folders with other pictures, but not the main folder. It’s not a timing issue where it needs time to open the folder, it simply flips off. Back to square one.

So I’m sorry, but I can’t recommend it.

### 5/5 — Runs on MiniMac with M4

*2024-12-16*

I have used this app on the iPhone for many years and just tried on the Mac with the M4.  Success! Great for aligning pairs.  Best to put pairs in a smaller album before combining.

### 3/5 — Does the job well, but so overdue for an update

*2024-11-18*

This is my go to 3D app, but the interface is dire and some of it looks like it’s from a Windows PC from 20 years ago! I have some lovely 3D images I’ve taken with it but it always feels awkward.

Also, when I use the main camera on my iPhone it takes a great HDR image, but this app doesn’t. I don’t know if Apple keep HDR for themselves but if not it would be great to update this app to use it.

### 5/5 — iPhone16

*2024-10-04*

iPhone16対応ありがとうございます

### 3/5 — Great app but..

*2023-05-03*

Hi. Great app to use for processing 3D images. However, from 3rd April 2023 I can’t seem to load images without crashing the app. I’ve tried deleting and reinstalling. Any advice please?

### 5/5 — It works

*2022-11-17*

Read apparently old instructions which said needed i3DCamera to take photos to use the app but I found instructions that showed how to take pictures within the app for stereo viewing. Having practiced for a short time I was able to produce good 3D images for viewing with a stereo viewer. Very cheap price as well.

### 1/5 — Awful

*2021-11-07*

I can’t open any photos at all to create a project, what a waste of money. Refund please!!!

### 5/5 — about app

*2021-09-23*

こんにちは。お手数をおかけしますが、アルバムから開けた写真はフルサイズではなく、拡大すると少しぼやけます。すみません、今後のバージョンでは改善されますか?ありがとうございました。

您好，麻烦您了，我发现从相册打开的图片不是全尺寸的，放大后会有点模糊。请问在以后的版本中是否会改进呢？谢谢。

Hello, excuse me, I found that the picture opened from the album is not in full size, and it will be a little blurred when zoomed in. Will it be improved in future versions? Thank you.

### 5/5 — Amazing

*2021-08-14*

This app is amazing it takes beautiful 3-D pictures on any phone

### 5/5 — DropBox?

*2021-05-28*

Love this app, but would love an easier way of getting MPO files from my Fuji W3 into it. If this could access DropBox for loading and saving it would save a lot of faffing about.
