App Cloning Tutorial

Use Bundle ID modification to run multiple instances of the same app and manage multiple accounts

What is App Cloning?

App Cloning works by modifying an app’s Bundle ID, tricking the system into recognizing it as a completely new, independent application. This allows you to install multiple copies of the same app and log in to different accounts without interference.

Common use cases:

  • Running multiple WeChat or QQ accounts simultaneously
  • Game multi-boxing (Main account + Smurf account)
  • Completely isolating work and personal accounts

Operation Steps

1. Import the IPA File

In the ESign “Library”, locate the IPA file of the app you wish to clone.

No IPA? You can obtain one via AppStore decryption tools or find shared resources within the community.

2. Modify the Bundle ID

App Cloning with ESign

  1. Tap the IPA file and select “Sign”.
  2. On the signature configuration page, locate the “Bundle ID (Identifier)” field.
  3. Add a suffix to the original ID, for example:
    • Original: com.tencent.xin
    • Modified: com.tencent.xin.clone
  4. Simultaneously modify the “App Name” to make it easier to distinguish (e.g., WeChat 2).

ESign provides a “One-click Clone App” feature. Once enabled, it automatically adds random suffixes to the original Bundle ID and App Name.

3. Sign and Install

  1. Select your certificate.
  2. Click “Start Signing”.
  3. Once signing is complete, click “Install to Device”.

Important Notes

It is recommended to enable “File Access” and “iTunes File Sharing”. This allows you to migrate resources (such as chat history) from the cloned app to a newly signed version once the certificate expires.

  • After modifying the Bundle ID, the data for the cloned version and the original version is completely independent and will not affect each other.
  • Some apps have device binding or risk control detection; cloning may trigger account bans, so please use with caution.
  • After the certificate expires (typically 365 days), the cloned version will need to be re-signed.

Preview of Results

Once installation is complete, two independent app icons will appear on your home screen, allowing you to log in to different accounts at the same time.
