### 4/5 — Sad To See A Feature Go

*2020-08-11*

This is, like, INCREDIBLY late, but I just opened up this app after letting it sit unused for a few years and now the multitouch has completely changed. I really miss the ability to direct the particles around the nucleus with two fingers, instead of...whatever is happening now when I multitouch. Any chance we could get that old multitouch back? Or is there a similar app?

### 2/5 — Clunky and outdated

*2017-06-25*

The active screen is just a portion of the iPhone 6s. Off center, clunky, no real atomic properties or simulation.

**Developer response:** The off center issue should have been fixed with version 2.1 - could you please send a pic to pdjapps@gmail.com with what you're seeing? Thank you!

### 3/5 — Okay, I'm upgrading my rating.

*2017-06-01*

I used to really like playing with this app, but after the last upgrade they completely changed it. I don't like playing with it now, but I have raised my rating to three stars instead of the one star rating I gave it for two reasons. First, I don't like it but it is still fun if you aren't mourning the loss of the old app. Second, the level of developer response I have received is above and beyond anything I could have expected. They seemed to sincerely want to get specifics about what I don't like. Nice.

### 4/5 — Won't work on IPhone 6 Plus

*2017-04-30*

First off, I love this app. It's a lot of fun to play with and waste time. However the one thing that's off is that the nucleus display is not centered on the IPhone 6 Plus. The touch activation is still dead center, just the nucleus is visually off and unsymmetrical and a bit annoying.
I've play otherwise on a friend's IPad and iPhone 7. But for my 6plus it won't be centered. Please fix. 
Nonetheless y'all are genius for making this app. Maybe next time include a vibrate function?

### 5/5 — Game is awesome 😁

*2017-04-23*

This game is awesome and worth every penny it keeps you busy and is really fun to play!!!😀 defiantly should buy!🙂

### 5/5 — Beautiful and mesmerizing

*2017-04-23*

I also have Particle Box, Cyclotron, and my favorite, Sand Garden. From what I have seen, this developer creates apps that are interactive art experiences that are wonderful and enjoyable. I wouldn't be surprised to learn that using an app like this is healthy for the mind, like walking a labyrinth. Get it!

### 2/5 — Needs more features

*2015-07-02*

This app is very good and fun to play with but it needs a lot more particles and particle size needs to be variable and needs a selectable color palette and other features to it

### 5/5 — 👍👍👍👍

*2015-02-21*

Keeps me occupied for hours after dropping a tab. 😜😜😜

### 5/5 — Fun and relaxing

*2015-02-21*

This is a very relaxing toy. It brings out the kid in me, letting me create and watch some very interesting and colorful patterns and animations.

### 5/5 — It's nice

*2014-07-22*

This app does everything they show it does, with high resolution and selectable effects.

## Version history (last 5 releases)

### 2.2 — 2018-03-23

This update from Apple will improve the functionality of this app. No new features are included.

Removed the show menu button. To show the menu simply tap a corner.

### 2.1 — 2017-05-02

- Fixed issue with nucleus not being centered properly on iPhone Plus models. 

Thanks for the suggestion for vibration - we tried it but unfortunately it didn't work very well!

### 2.0 — 2017-04-18

Major overhaul! The app was lacking in interaction and variability. 
What's new:
- Mode selection has been removed from the tools menu
- Modes can now be accessed by the number of fingers on the screen 
- A nucleus was added which gets randomized by touch thus changing the way the particles rotate (using Mode 2 from previous version)
- Icon updated to include a nucleus

Thanks for using Atomic Toy and we hope you enjoy this new version! We tried to keep what was good and combine it with new features.  - PDJ Apps
