TweakDoor is a third-party program installer, but it is completely safe to download and install on your iOS device. Unofficial programs, games, and screen recorders that have not made it into the official app store can be downloaded. Despite Apple's rigorous ban against installing potentially malicious programs, TweakDoor allows you to install unapproved apps without jeopardizing your security.
TweakDoor is available for free download and installation. Simply go to the TweakDoor website and follow the steps to download programs. Then, to install the program, follow the onscreen instructions. An "Untrusted Developer" error notice will appear. To remedy this problem, you must first authorize the developer's profile. Open the TweakDoor app and follow the instructions after you've allowed the developer.
