Among the best
I have downloaded and tried all the major apps, as well as paid for a couple and this is the one I stayed with. It really is the best among them. Of course it still could use some tweaks, like Apple Watch and split screen capabilities (although I havent tried for a while so it may now have this). If you are willing to pay, save your money on the others and just buy this one.
