## What is Copper?

Open any EAGLE CAD file (from version 6 and above) directly on your iPhone and investigate the PCB layout and schematics with your finger. Select parts and signals, manage parts and Bill of Materials.

Copper creates 3D versions of your PCB including parts that you assign from our extensive 3D model library to your footprints. Copper then renders a photorealistic representation in real time that you can touch, rotate and move in a virtual studio. Setup lights and materials like the solder mask or the floor.

Import EAGLE files from any source like the web (just download a ZIP file with EAGLE files), from Github, your Dropbox, or send PCB files directly via Airdrop, Mail or iMessage to your iPhone or iPad.

Every file you import is kept in Coppers library. This way you can build up a nice library of PCBs and Schematics right in your pocket. 

Copper is also available for the Mac and both share the same codebase and file format.

## Key features

- View EAGLE CAD files
- Analyze PCB layouts and schematics
- Create 3D PCB models
- Assign 3D models to footprints
- Real-time photorealistic rendering

### 1/5 — Nope

*2023-03-08*

Won’t download anything…why? Seriously?

### 3/5 — Useful app

*2022-09-03*

Hi,this is useful app but it’s needed to update to be better but don’t happen,I don’t know why!!…?
But good and only this one work to open eagle files
It will be great that happens for altiume “.pcbdoc”  and “gerber” files but i don’t find any app in app store😔😑

### 2/5 — Great idea, but too glitchy to use

*2020-05-30*

I really wanted this app to work! Being able to review my PCBs on my phone or iPad would be super convenient. I was able to view the 2D Eagle files without problem, but the 3D views just don’t work. In one of the demo boards when you rotate to the bottom side, it is mirrored. On another board, it renders pads, but no board or traces. If the 3D render worked, it would be a 4 star app.

The last feature it’s missing to be really functional is to support loading boards from the Files app. Currently, you can only load them from sources like a web server, Github, or Dropbox.

### 5/5 — Great app

*2019-11-26, version 1.0.3*

Can be buggy but so is eagle!

I use this app everyday and it works great for me.

### 3/5 — Great potential, stale

*2019-11-25*

This app has great potential but it is not actively
developed, and lots of bugs have accrued.

### 1/5 — Can’t import

*2019-10-30*

Can not import anything from Dropbox.

### 2/5 — Screen glitches

*2019-06-27*

This app is very useful, I’ve enjoyed reviewing my projects on the fly anywhere away from my computer, but after a week of having this app installed my screen on phone phone started to glitch, when using the app I’d tap several times on something and no response, then suddenly all my taps quickly happened and was unstable. Outside of the app my screen would do the same thing, the touch screen would stop working in sections, I would force quit the app and the problems went away until I opened the app again. After upgrading my phone I installed the app again thinking it was just the last phone. After a week on the new phone with the app installed same issues came up. I deleted the app completely and now my phone is acting normal. Not sure what’s happened but it’s sad to not be able to keep the app. It’s great.

### 4/5 — Good App

*2019-05-07, version 1.0.3*

I like this app. I use it a lot to check circuits and components when assembling PCBs. The schematics are not perfect, but they’re good enough, and better than printing them to paper from Eagle. I’ve seen none of the issues reported by other reviewers. The only thing that bugs me is importing from iCloud which is cumbersome

### 1/5 — Utterly useless

*2019-04-04, version 1.0.3*

Give me a refund please. This app just doesn’t work. It won’t allow me to import .sch and the .brd files just come up blank. Complete waste of time and money.

### 5/5 — Excellent pcb app for eagle cad

*2018-11-18, version 1.0.3*

It’s a great app. Good value for money app. It’s not perfect - but I fInd it very useful. Always wanted to review my pcbs on the tube on way to work...

 although, if I had one request... I would ask the author to allow some form of categories, perhaps folders- I have too many circuits for one list!
