You will be able to see Clash stats in the app. Firstly, when you are clicking into a room you will be able to preview the top 3 players across all rooms in terms of 'Top KCAL Earned' or 'Top duels Won'.
If you want to see more details about your own Clash Stats you can find these in your profile tab. Click 'See More' for the full details. This data is also published to the leaderboard tab so you can check it out there under the 'Clash' section of the leaderboard located in the top right corner.
So, check out your stats and compare them to your friends:
