app that makes you use keyboard??

beginner but I’ve been trying out different apps to see what I like using, and I ended up deleting this app that made you type in the hiragana with your phone’s keyboard. I can’t remember what it’s called. I think it became pay to use after the aeiou section, but honestly it helped me remember things better than these off brand doulingo apps and anything that makes me guess a sound.

anyone know what it’s called?
