How to Save Youtube videos to Iphone camera roll without jailbreak?

Downloading YouTube videos for offline use, or just to watch later, is easier said than done on iOS. Due to restrictions placed by Google, various applications in the iOS App Store, like Video Downloader or Free Video Downloader, no longer work when attempting to save from YouTube's website.

Fortunately for us, after testing multiple apps, I've found one that makes YouTube downloading not only extremely simple, but also convenient by having downloads go directly to your iPhone or iPad's Camera Roll.
