Looking for a good app to learn Arabic vocabulary (Egyptian)?

Hello! I'm looking for an app that allows me to learn Arabic on the go and/or review vocabulary. The problem: I'm learning Egyptian Arabic, for which Duolingo, for example, doesn't offer a course. It would be sufficient for me to enter the vocabulary from my lessons somewhere myself and then quiz myself, but for that, I need a vocabulary learning app that also supports writing Arabic characters. Does anyone have any suggestions? Thanks in advance!
