I use byword for OSX and I love it, but the iOS version is garbage.
Theres no way to hide basic things like word count, there is an omnipresent bar on the bottom of the screen that is ugly and serves no purpose. Of course, it cant be hidden as well.
The app lacks basic features, is extremely expensive compared alternatives and is visually hideous.
Ymx. about Byword, v2.5.1
