The layout of this Life point counter is amazing. With the dice, the coins, the deduction of life points is easy with the buttons. But having an iPhone X, the UI doesn’t work. The top half of the screen, you cannot access the coins and etc. needs to be patched. ### 5/5 — One of the best & simple Duel calculators *2018-06-06* Yes, it support iPhone X.
