Built-in Wi-Fi Web Server
Start a high-speed local HTTP transfer server directly inside ESign to quickly send IPAs from your Mac or PC browser over local Wi-Fi without cables.
Custom App Store & Sources
Add direct JSON repositories and third-party community sources to browse, update, and download popular tweaked apps directly from within ESign.
Data Backup & Extraction

Walkthrough
How to Install & Use ESign
Follow these 4 simple steps to set up your certificate and begin signing packages.
Download & Install ESign
Download the official ESign IPA using the download button above or trigger direct OTA installation via Mobile Safari. If installing via IPA, use AltStore, Sideloadly, or Scarlet for the initial install.
Import Signing Certificate
Open ESign, navigate to the Manage tab, and import your .p12 certificate file along with your provisioning profile (.mobileprovision). Enter your certificate password when prompted.
Sign Any .IPA File
Download any IPA file from Safari or import it from the iOS Files app. Tap the file in ESign, select Signature, configure optional tweak injections or bundle ID changes, and tap Sign.
Trust Profile in iOS Settings
After tapping Install, navigate to your device's Settings > General > VPN & Device Management. Locate your imported certificate profile and tap Trust to launch the app.
Block Apple's OCSP revocation servers (ocsp.apple.com / ppq.apple.com) using a NextDNS profile to prevent certificate revokes.
