Android users are very used to resorting to alternative app stores other than the official Google Play. However, Apple users are usually more limited in this sense, due to the greater difficulties to install apps from unknown sources on iOS devices. Nevertheless, there are alternatives to the App Store, and one of them is this AppEven.
Find the apps that aren't available in iTunes
This application is an app store from which we can download all sorts of applications, both those we can find in the official App Store as well as others that haven't been accepted and even modified versions. It's equipped with a simple user interface that allows us to easily browse through the store's contents.
The greatest advantage of this tool regarding Apple's App Store is that we'll be able to download modified apps, such as Instagram, WhatsApp or YouTube clients with extra functions and features. There's also a special section for games and yes, you'll be able to download quite a few paid games for free... although we must warn you that that wouldn't be very ethical on your behalf.
