💡 Wi-Fi Background Refresh: AltStore will automatically refresh the app certificate every 7 days in the background when your device and computer are on the same Wi-Fi network.

🚀 Method 2: Sideloadly (Instant Drag & Drop)

🔧 Essential Troubleshooting & iOS Permissions

1. "Untrusted Developer" Alert on First Launch

iOS blocks apps signed with personal Apple IDs until you trust them once:

Go to Settings → General → VPN & Device Management. Tap your Apple ID under Developer App, then tap Trust "[Your Name/Email]".

2. "Developer Mode Required" (iOS 16, 17, 18)

Apple requires Developer Mode enabled on iOS 16 and newer:

Go to Settings → Privacy & Security, scroll to the bottom, tap Developer Mode, and toggle it ON. Restart your device, then tap Turn On when prompted.

3. Free Apple ID 3-App Limit

Free Apple developer accounts allow a maximum of 3 sideloaded apps at a time. If AltStore or Sideloadly returns an error about active app IDs, uninstall or deactivate an unused sideloaded app first.
