Install without a Mac

Open this page in Safari on your iPhone or iPad. Upload your developer certificate; we sign only DefianceSign.ipa and delete your files when done.

Before you upload: use an iOS App Development or Ad Hoc profile (not App Store distribution). Your device UDID must be in the profile. Register it at developer.apple.com → Devices if needed.

After DefianceSign is installed, import the same certificate inside the app to sign other IPAs locally.
Development certificates expire after about 7 days. Come back here or use Sideloadly to install again.
The app cannot update itself. Use this page or sideload a new IPA from GitHub Releases for updates.

If iOS says “integrity could not be verified”

Profile type must be Development or Ad Hoc, with your UDID listed.
Use a profile for a specific App ID, or one that includes net.defiancesign.app. Team wildcards like com.yourteam.* usually do not cover our bundle ID.
After install: Settings → General → VPN & Device Management → Trust your developer profile.
Turn off VPN, set automatic date/time, or try DNS 8.8.8.8 if verification keeps failing.
