Tablet + pen for bunpro — what app/setup for keyboard?

Hi everyone.
I want to get some more writing practice in, by doing my daily bunpro activity with my tablet (xiaomi mi pad 7) and the pen, instead of just typing it.

So far, I installd the japanese gboard language with the large space for handwriting — and that works for about 90% of all kana. Each kana that starts with a straight line, top to bottom, the keyboard immediately renders into a '1', which is super annoying. Sometimes i can only get it to recognise what i want to write by switching to the keyboard setup with keys and pressing the right button, just to switch back and continue handwriting the rest of the kana.

(Plus, Gboard sometimes gets 'jumpy' whenever the page reloads, which is frequent on bunpro!)

Does anyone have a recommendation for an alternative set up? Some other keyboard app? Some custom user app for bunpro? (Or maybe wanikani??)

Alternatively, I guess any kind of app that would ask me to write beginner-ish style sentences and words would also work, but honestly, I'd like to finish up my daily bunpro/wanikani and get some handwriting practice in at the same time, as opposed ot adding another source of daily exercises to do 🙂
