I'm using an iPhone 6 with Swiftkey.. I'm really used to it but it's laggy compared to the stock iOS keyboard. Is there any good keyboard like Swiftkey (extremely good predictions and that "tap map" thing where it creates a virtual keyboard based on how you type) but lag-free as the stock one? Please don't recommend me the stock one, I've tried it but I can't get used to it (having to touch two buttons to insert a comma is much slower than the touch and swipe thing on swiftkey). Thanks!
