iOS: Cydia, Ad-Block, Themes etc. (no Jailbreak required).
People apparently don't realise you can actually install custom features in iOS without jailbreaking your phone.
Although jailbreaking your phone will give a better experience, you can enjoy it without.
On this site you can install Torrrent apps, Emulators and apps to record your screen. http://iemulators.com
I mean, I don't want some webapp. I'd prefer to have the actual Cydia in my phone without the hassle of jailbreak.
You can't have that obviously. But this works the same was as Cydia, and you get access to all the tweaks, hacks etc.
Jailbreak isn't a hassle anyway. You chuck the device in, open up a jailbreaking program, watch two youTube clips, then suddenly its done. I don't even remember jailbreaking my iPad that much because it wasn't a hassle. You just plug it in and go.
It worked on my iPod but that has iOS 6. Lemme try on my 5s.
EDIT: It didn't work Mess.
Changed it too "a limited version of Cydia" to be fair. I haven't really looked at this, since I don't really use Cydia type stuff.
I'm just going by the response on a YouTube video I found. I know the emulator's work for sure though.
They are great.
People are only taking advantage now. 
Surprised more people don't take advantage of this stuff.
but there's some awesome features that don't require it so that's good as well.
