Signed builds now expire automatically

The platform now deletes signed output after its live window ends, which keeps storage usage under control and avoids stale install links.

The homepage now surfaces latest IPA sections

Recent uploads, app categories, and article sections are now separated to make the library easier to browse on both desktop and phone.

Device login remains the recommended onboarding path

Safari-based UDID login is still the cleanest path for certificate retrieval and later signing, especially on iPhone.

How To Fetch Your Certificate

After device login, the certificate page can fetch the certificate and provisioning profile tied to your UDID and keep them ready for later signing jobs.

Go to the certificate page

The certificate page is the bridge between device login and the signing system. If you are already logged in, you do not need to repeat the profile flow again.

Fetch and save

When the provider confirms the certificate for your UDID, the website stores the certificate files for that device session so later signing jobs can reuse them.

How To Download And Install A Signed IPA

Pick an app, confirm the signing options, wait for the job to finish, then use the generated install page on the same iPhone that owns the saved certificate.

Start from the app page

Each app page is now the entry point for the sign-and-install flow. The platform can ask for bundle, name, or version overrides before the job starts.

Wait for the signing stages

Large apps take longer because the original IPA may need to be fetched, unpacked, signed, repackaged, and published again before the install manifest is ready.

What To Check Before Signing

Most signing issues are predictable. Check certificate readiness, app size, bundle values, and whether you are reusing the correct device before you start.

Certify Team2026-03-22

Certificate status matters first

If the certificate is not ready, the signing job cannot finish regardless of the app you choose. Make sure the saved certificate status is healthy before starting.

Large IPA files take longer

A multi-gigabyte app will take noticeably longer than a small utility. That affects both the provider-facing signing flow and the final install wait time.

Performance4 min read

Why Downloads Or Signing Can Feel Slow

The delay is usually not random. Large IPA size, remote storage fetch time, queueing, certificate prep, and repackaging all contribute to the final wait.

Certify Team2026-03-22

The app has to move around

If the original IPA lives in remote storage, the server must download it first, then produce a new signed build, and then host that build for installation.

Temporary disk and packaging matter

Signing uses temporary disk and work folders while the app is being unpacked and rebuilt. For large apps, that alone adds real processing time.

Troubleshooting5 min read

Troubleshooting Common Install Problems

If installation fails, the problem is usually tied to device login, certificate state, browser choice, or an expired signed build rather than the library UI itself.

Recheck the device session

If the UDID login was never completed, later certificate and install actions will behave inconsistently. Start there before troubleshooting anything else.

Use Safari on iPhone

The cleanest install path still expects Safari. In-app browsers and social-media webviews frequently cause extra prompts or broken handoffs.
