Charles Proxy for iOS lets you capture and inspect network requests and responses on your iOS device. You can view metadata, headers and bodies in the app, so you can finally debug your app’s networking issues without a computer.

Charles Proxy for iOS is a new app from the creators of Charles Proxy for desktop.

Turn Charles on when you want to start capturing. Charles captures your network requests and responses in the background while you test your app or website. Return to Charles to inspect the requests and responses.

If you also have Charles on your desktop, you can transfer recorded sessions to your desktop to explore them on the big screen.

Charles creates a local VPN on your device. All of your network traffic passes through Charles on your device, and then out to the internet as usual over either WiFi or Mobile / Cellular data. There is no remote server involved, and your data always remains private to you.

* SSL Proxying to view SSL requests in plain text
* View and share request and responses bodies
* Syntax highlighting for text request and response bodies
* Measure network performance over WiFi or Mobile / Cellular networks
* Block requests to nominated hosts

Invaluable, solid, intuitive!!

Perhaps it is just the nature of my work and interest, but I use this app more than any other app I’ve ever purchased. I recommend it and the desktop version often. The insight it provides about what your app is doing is so helpful, and a bit disturbing to see how much and how frequently other apps are transmitting data about you.

For example, you can easily see that your phone transmits every character you type as you type in real time to Apple, including your exact longitude and latitude while you may only be searching for something on your phone, a private contact, a personal note, or other critically secure document on your device.


Useful Info

The app is primarily useful for developers debugging their work, but if you want to get an idea of how many apps are sending data in the background and see some of that information, then this app is revealing. It works perfectly, but you have to read and follow the instructions. If you don’t follow the instructions, then it won’t set up correctly. As we used to say RTFM.


Finally it is on iOS

This is an amazing accomplishment for the team and for users. Now it is much easier to inspect traffic for application troubleshooting without having to go through hoops of setting up a proxy though a computer. It was a very smooth process to setup and I think this will allow more people to try the tool out and include it in their dev workflow.
