### 1/5 — Doesn’t let me draw

*2024-11-21, version 2.0*

Every time I try to draw anything it randomly moves the lines and won’t let me finish an image.

### 4/5 — Nearly there

*2023-12-19, version 2.0*

I really like this app, I just wish I could import a depth map image to be rendered. It’s the only thing missing from the app. Once I can import an image from the photo reel (aside from being a pattern), I’ll be all set

### 1/5 — Does not work

*2022-12-24, version 2.0*

No designs observed , just a 3D pattern pressent! Wasteful!

### 4/5 — Amazing but…

*2022-06-22, version 2.0*

The game is amazing and i Get so confused with optical illosions!but i never see the 3D image i do

### 4/5 — Ham

*2021-01-25, version 2.0*

nice app I am happy with it no complaints.

### 2/5 — Email disaster

*2020-07-22, version 2.0*

I spent two hours creating around 30 good images then emailed them all using the Share icon and I got no emails.
Next time I will have to screenshot my creations and send them from my reliable photo album sharer.
Disappointed in that, but the actual autostereograms, are awesome.

### 5/5 — Best stereogram generator on the market

*2020-05-11, version 2.0*

Hands down best grams. I use this many time a day to make secret messages so the NSA can’t tell what my friends and I do on weekends

### 5/5 — Awesome app

*2020-05-11, version 2.0*

So good, all the bad reviews are just people who cant do double vision. I bet this was really hard to make. #freemyniggasmelly

### 1/5 — Really bad app, hackware

*2019-08-20, version 2.0*

Possible hackware do not download! Basically it promotes itself as some kind of Kid Pix for the phone. But all it does when it starts is it shows a magic eye pic with the app’s watermark on it, and it is really hard to get it to close! I had to open Siri to clear the screen. Do not download!

### 1/5 — Liam

*2019-03-19, version 2.0*

It never gets past the first screen. It force closes the app within 30 seconds of opening.
