A: Yes, completely free. No subscription, no hidden fees, no ads. Q: Is UnKeySign safe? A: Yes. The web signing service deletes uploaded certificates immediately after signing. No data is stored. The app itself runs locally on your device. Q: Do I need a jailbreak? A: No. UnKeySign works on stock (non-jailbroken) iOS 14 and later. Q: Do I need a computer or Mac?

Q: Does it work on iPad? A: Yes, both iPhone and iPad are supported. ### Signing & Installation Q: How do I sign an IPA? A: Visit unkeysign.com on Safari → tap "Install on iPhone" for one-tap install, or upload your own P12 + mobileprovision for custom signing. Q: What is a P12 certificate? A: A .p12 file is a PKCS#12 archive containing your Apple Developer signing certificate and private key, protected by a password. Q: What is a mobileprovision file? A: A provisioning profile (.mobileprovision) links your certificate to specific devices via UDID and specifies which app bundle IDs are allowed. Q: Where do I get a P12 and mobileprovision? A: From the Apple Developer Program ($99/year), or from third-party certificate providers. Some free options exist with limitations. Q: How long does signing take? A: Web signing typically takes 15-60 seconds depending on IPA size and server load. Q: Can I sign any IPA on the web? A: The web service signs the UnKeySign app. To sign custom IPAs, install UnKeySign on your device and use the in-app signing engine. Q: Why does it say "Unable to Install"? A: Common causes: (1) your device UDID is not in the provisioning profile, (2) the certificate is revoked, (3) the profile expired. Check with your certificate provider. Q: Why does it say "Untrusted Developer"? A: Go to Settings → General → VPN & Device Management → tap the developer name → Trust. Q: Can I inject dylibs? A: Yes, the in-app signing engine supports injecting .dylib and .framework files into IPA before signing. Q: Does it support enterprise certificates? A: Yes, enterprise (In-House) certificates work and don't require per-device UDID registration. ### App Directory Q: What is the App Directory? A: A searchable catalog of 14,000+ iOS apps crawled from multiple sources. Each app has its own page with metadata and install instructions. Q: Can I download apps from the directory? A: The directory shows app information. To install, use UnKeySign's signing feature with your own certificate. Q: How often is the directory updated? A: Automatically every 12 hours. ### Alternatives & Comparisons Q: What are alternatives to UnKeySign?
