Update 1/6/2013: A new alternative, called 25pp, is available. Click here for the tutorial.

Update 1/5/2013: It appears as though they have removed paid apps from their app library, and only free ones remain. Nobody knows if it will stay like this permanently or not.

Disclaimer: As usual, this should only be used for trying applications before determining whether or not that you should buy them. Believe it or not, but I strictly follow this, as you’ll see in the video below.

With the closure of Hackulous and the magical disappearance of Zeusmos, where will people go for cracked apps? While many app databases, such as IDWANEO and AppCake, still exist, one then wonders how you should go about installing the apps without a jailbreak, and without having to deal with certificates and/or provisioning profiles.

A new method, courtesy of Chinese website http://kuaiyong.com/, takes things a step further by allowing you to install such applications without a jailbreak, and without having to do anything special. It’s 100% free, and it 100% works (for now, unless Apple somehow figures out how to close this). Quite honestly, it’s a bit scary to see how far iOS app piracy has come. Read on for the tutorial.

There is a catch, however. You need to download and install software onto your computer, of which is Windows only at this time. NOTHING MALICIOUS IS INSTALLED ONTO YOUR COMPUTER. If you’re on a Mac, you can still run the software through Windows via Boot Camp/EFI as well as in a virtual machine. In the tutorial video below, Parallels 8 was used.

The way it all works is extremely simple:

  1. Download the software
  2. Install the software
  3. Run the software
  4. Download the apps
  5. Install the apps

The entire program is in Chinese, so it might not be easy to some. However, with some experimentation (aka clicking on things), I figured out how.

Kuaiyong’s main screen.

Here’s what the main interface looks like. You’re presented with some of their more popular applications. Above all of this is a search box, which is pretty self-explanatory.

Searching for Angry Birds.

If you were to look for Angry Birds, this is what the results screen would look like.

The application screen.

The application screen.

After you’ve selected an application, you’ll be presented with its information, which includes a description, other information, and some screenshots.

The download button is the red button that you see below the app’s icon. Clicking on this will immediately begin the download.

The downloads screen.

The downloads screen.

While the language of this screen isn’t English, it should be pretty easy to understand what’s going on.

The actual speeds of downloads vary quite a bit, and aren’t by any means fast, however they can be resumed whenever you’d like.


Angry Birds has completed.

When a download has finished, the red pause icon will switch to a grey button. Clicking on this button will immediately begin the installation to whatever device that is currently plugged into your computer.

The installation in progress.

While the app is installing, you’ll see the status in the form of a live-updating percentage.

Lastly, here's the app.

When the installation is done, the app that you’ve installed will instantly show up on your device.

And that’s all there is to it. While it might be inconvenient to have to use a computer to do it, it’s quite interesting how this seems to work without requiring you to have any developer certificates or provisioning profiles installed. Hopefully, once this becomes more popular, more details as to how it works will emerge.

I tried to do some digging around it myself, and it turns out that it simply downloads .IPA files. Inside is a “bppinfo” file that contains some information that seems specific to Chinese software, and even if adding this file into a different IPA, it won’t work. You could straight-up install the .IPA via iFunBox, but opening the application will prompt you to enter an iTunes ID and password, so cancelling this will close the app. Installing the same .IPA through the software will magically make everything work.

Please refer to our tutorial video below if you’re having trouble with the software.
