The League Friends app connects directly to your existing League of Legends account and friends list and lets you stay in touch with your League Of Legends squad. It lets users organize a late-night scrim with their ranked squad or a little nice chat about whom to plunder next.
Download and install this app on your phone or your tablet running Android 4.1+ (Jelly Bean) but it is mainly targeted for smartphones with Android 6.0 (Marshmallow) and it will automatically sync your progress once you have finished logging in from your already working League of Legends account.
Once you are done with logging, this app will ensure that you’ll get invited when your team opens up a lobby or you can ignore them like a boss by turning notifications off.
You can see your friends list, add new pals, and chat one-on-one at launch and the app description says that the app will keep adding new features and evolve like League of Legends does.
The official 1.0.2 version of League Friends is of 9.75MB and you can download it from the below-given source link.
