How to Install IPA file on iPhone or iPad without jailbreak.

Example: install ifile.ipa

Step 1: Download the iFile IPA from here and Cydia Impactor from here.

Step 2: Connect your iPhone or iPad to your computer via USB.

Step 3: Open Cydia Impactor.

Step 4: Drag and drop the iFile IPA onto Cydia Impactor.

Step 5: You’ll be asked to enter your Apple ID and password. This is sent to Apple to generate a signing certificate.

Step 6: Cydia Impactor will begin installing iFile onto your device. Once done, you should see the app’s icon on your Home screen.

Step 7: Before opening iFile, go to Settings > General > Profiles (or ‘Device Management’).

Step 8: Open the profile labelled with your Apple ID, and then tap on the Trust button.

That’s it. You can now use iFile to browse your device’s file system and view any file that you wish. Make sure that you don’t alter the system files to avoid bricking your device.

With this method, you have to re-install the app every 7 days. This is because the app is signed with a free certificate that lasts for 7 days. After this period, iFile will crash and you will have to re-sign the certificate by reinstalling the app via Cydia Impactor. If you use a developer Apple ID, the certificate will last for one year.
