IoS Emulators on Windows?

Hello all,

I was just wondering is there a free and easy to use IoS emulator like there is in comparison to Android emulators?

For example, here is an android emulator:

https://www.bluestacks.com/

Also, to download Android apps to my computer it is very easy by downloading the APK package, is this possible with IoS?

Thank you

Sonam T.
