FAQ
Can't find an answer? Ask in our community
Is ESign free to use?
ESign offers a free standard build with core signing features. The Custom Stable build includes a stable certificate and additional services — see the install page for details.
Why can't I install the signed app?
Make sure Developer Mode is enabled under Settings → Privacy & Security, and that the certificate is trusted. If issues persist, check that the certificate is still valid.
Which iOS versions are supported?
ESign supports iOS 16 and above, including the latest iOS 26.x.
Does signing require uploading my IPA?
No. All signing happens on your device. Nothing is uploaded — your files and privacy stay local.
Do I need to jailbreak my device to use it?
Not at all. ESign uses Apple's native signing mechanism, so no jailbreak is needed and your device security is unaffected.
