I've learned about a #quikwriting, an alternative text input method using a stylus/finger focusing on continuous flow:

For Android, there was a now no longer maintained keyboard called #8pen.
Now, it has an open source, spiritual successor called #8vim: https://github.com/flide/8Vim

I was wondering if anyone has ever tried using 8vim/8pen or a similar (quikwriting like) input method. If so, how was it? Is the learning curve steep? Did it increase your input rate? Would you say it's worth learning to enter text on a touchscreen?
