### 3/5 — Good for a free demo but…..

*2025-04-06*

It’s free and awesome to play with it. However when you arrange the spheres so that you look through a glass sphere then it has a bug. It does not show spheres behind it. It shows the scene walls and even shadows of the sphere behind the glass sphere. But the sphere behind is invisible regardless if you make it normal solid or metal.

### 5/5 — Fantastic App

*2025-03-22, version 1.2*

Great app for trying out the tech, super easy to use and interesting. Very underrated.

### 1/5 — crashes a lot

*2024-07-28*

it just crashes too much

### 4/5 — Crashes a lot

*2024-01-22*

It’s a great app but it always crashes before the image is done

### 1/5 — It keeps crashing

*2023-10-13*

It’s a cool app but it keeps crashing every time it goes for more than 10 seconds

### 5/5 — This is the best and fastest path tracer.

*2023-06-19, version 1.2*

Can we get the source code.

### 4/5 — Nice

*2022-06-23, version 1.2*

This app is definitely very cool, but even though I just downloaded it 2 seconds ago, it has crashed more times than all the other crashes I have got combined.

### 5/5 — Frequent crashes

*2022-06-15*

Apps keep crashing on a 2019 apple device

### 2/5 — Wont run on my iPad Pro. (2018)

*2022-04-24, version 1.2*

Please add support for some more devices that clearly have more power than a Series X.

### 4/5 — Great piece of tech. Would be better if it didn’t crash.

*2022-03-05, version 1.2*

I am using an iPad Pro 2018 model so this app should NOT crash that easily… yet it does. On my old iPad Air 2 it worked fine when i used it in 2019. It also worked fine before iOS 15.
