Kodi is a multimedia program to view pictures, stream videos, listen to music, etc. There are many addons available for Kodi. My favourite is 1Channel. Similar addons are Exodus and Genesis. I have yet to use either of those but from other people I've heard using them, they are pretty good.
Kodi is available for pretty much every OS, including mini-computers, like the Raspberry Pi. However, for Apple devices, you will need to jailbreak it in order to install Kodi. Kodi is available on Android boxes, which is why more people are starting to lean towards buying them rather than the Apple box that includes shit all and of those that it does include, you can get them for free on Kodi and Kodi has EVERYTHING and I do mean EVERYTHING where as Netflix, Shomi, Hulu, etc. are limited and have restrictions based on accounts and what country you reside. The worst part about those things is that you have to pay per month to use them and you get shit all. With Kodi, as I said before: there is no bullshit when it comes to Kodi.
There are many tutorials on YT and Google on how to set it up.

When it says shit about setting a custom domain or turning off metadata, IGNORE that and just start using it.

Do NOT buy from China! You know how those gooks are with electronics and shipping. You'll be waiting anywhere from a month to six months just to get your fucking package. Select "Item Location" from the left and choose your location. If you already have a computer or a tablet, you won't really need this, unless you want to watch it on the big screen, but there are ways to hook up your computer to your TV, provided you have the proper (modern) TV, hookups and computer ports. YT how to do that.
If you need help, just let me know. I hope you enjoy!
