Quick Start
Install ESign in 5 minutes and start your first signing process
Before You Begin
Before installing ESign, please ensure your device meets the following requirements:
- iPhone/iPad running iOS 16 or higher
- P12 Certificate (Custom or Free version)
Tip: If you just want to try it out, you can choose a free certificate (available sporadically). However, we strongly recommend purchasing a Custom P12 Certificate for exclusive and stable use.
Step 1: Choose Your Installation Method
ESign offers two installation versions:
| Version | Target User | Certificate Validity |
|---|---|---|
| Custom P12 Cert | Long-term use / Stability | Longer (Recommended) |
| Free Version | Occasional updates | Usually expires in a few days |
| Self-Sign | Existing certs / Developer testing | Depends on your own certificate |
Go to the Installation Guide Page to select the version that suits you.
Step 2: Start Installation
If you have your own certificate, please download it to the “Files” app in advance. If you are using the Stable version, please have your “Certificate Code” copied and ready.

FAQ
Prompted with “Unable to Install” after signing? Check if Developer Mode is enabled and ensure you have trusted the corresponding certificate in Settings.
Cannot find the imported IPA? ESign supports importing from the “Files” app, or you can click an IPA link in Safari and choose “Open with ESign.”
Unable to import IPA via sharing? Due to system restrictions in iOS 26, files may not import directly to ESign via the share sheet. Please save the IPA to “Files” first, then open the ESign “Library” to import it.
