Apple's notoriously picky about what apps are allowed in their store, which means a lot of great apps get locked out. Jailbreaking has always been the go-to method for getting unapproved apps, but jailbreaking can be a hassle. If you're just looking to get one or two non-Apple-approved apps -- like Kodi, video game emulators, or even the f.lux-like Gamma Thingy, side loading is the way to do it. The process is free, it's easy, and it only take a couple minutes.
