On Android, it's more common to find tweaks that offer us the chance to modify functions within applications and games that usually aren't allowed, such as carrying out in-app purchases without paying. But that doesn't mean that there aren't any for iPhone. In fact, here's IAPCrazy.
Make in-app purchases without spending money
This application allows us to modify the functions of different applications that we'd usually have to pay to use. For instance, we can use it to remove adverts from apps or to purchase certain items in some video games.
Once we install the application, for which purpose we'll require jailbreaking our iPhone, we'll be offered a list of apps and games compatible with this tweak. If the game we want to modify appears on the list, we simply have to press Get More Plugins.
When doesn't IAPCrazy work?
You might find that the app doesn't work just after a major update to its servers or in the case of online games of the likes of Clash of Clans, with all the action taking place while connected to a server. In any case, your best bet is to always download the latest version of this app in order to get hold of all the new improvements... and no, it's definitely not very legal.
