iOS 7 Screen Recorder

Hello! I really want to record my iOS 7.1.2 screen. I also have some limitations.

• Non-jailbroken. I am not even 1% interested in jailbreaking.

• It must be free! My Apple ID is not linked to a credit card.

• It must be legal. I do not want my warranty voided.

• It must be a screen recorder. Not just a simple screenshot.

• No computer needed. I am not near a computer right now.

• No survey! I hate surveys!

Thanks for the help if you decide to reply. Remember the limitations. Thanks.
