Believe it or not, not every corner of the internet has been taken over by astroturfing as of yet!
I'm genuinely just sharing a cool keyboard app that has made my use-case far more fun for me. Another such app I used for a while was MessagEase, but unfortunately they went subscription-based (and also it was slower, even after a huge amount of practice).
I had initially mentioned the custom keyboard app I was using. I have since edited the post to remove that, since I'm genuinely interested in people's answers and don't want them to think this is an ad.
