I have used a program “keyboarding essentials pro” to speed up my typing in english.
Mainland has Typease by Kingsoft for helping Chinese learn to type faster but I think it is pinyin based.
Is there such a thing for bopomufu?
I see many Chinese people use two or four fingers and don’t use their other fingers. They don’t know who much faster they could write(and maybe think) if they had a software to act as a typing coach.
