You should be able to do it on the app. I am using it on iPad and access as follows:
1. Open app (the obvious bit )
2. Use tab at bottom to select My Clan.
3. Top right of screen select Manage Clan.
4. On left of screen select Clan Roster.
It then lists everyone in your clan and gives their K/D and Win %. You have the option of changing role or kicking them from the clan. If you go into more detail on the memeber (which is pointless as it only shows what their loadout was the last time they played and if they prestiged on the previous two games) then you will go back to a different screen and have to navigate back again. Hope that helps.
