The Chest unlocker for Clash Royale can simply doing one thing— get all Chests unlocked online for you.
It won’t be necessary for you to stay online and check the Chests after some hours over and over again. All this app could do is unlock the next available chest after the current one has done. As you have installed this app, you will never set up an alarm to remind you to do this by yourself.
Just enjoy!
