In general I like the concept and wanted to use it for learning characters and stroke orders for cantonese. When I searched for 哋 I was told it’s advanced vocabulary and I have to purchase it. That’s what I did, just to recognize that they don’t give you the writing function for this one. Only the translation of the word. Could have used a dicanary for that and lost about 11€ cause I can’t use it for the purpose I was looking for.
