The HappyMod interface looks like a basic marketplace where you’ll see different apps organized by games or tools. On the other hand, you’ll also find a window where you can find APKs that have been uploaded to the catalog recently.
One of the most interesting features in HappyMod is that for each app you’ll see the modified parameters that the version includes. For example, if you download Clash of Clans you’ll have unlimited gems and elixirs starting on the first level.
HappyMod is a really useful tool if you want to download patched apps that you can’t find in the normal marketplaces.
