Work through this consistently and you'll build the real basics of Arabic — enough to keep going on your own.
You won't come out the other side fluent overnight. But as you keep reading Qur'an alongside this, you'll start noticing things — a root you recognize, a pattern you've drilled, a word that used to be a blur now standing out on its own. That's the goal: not memorizing this app, but building a mechanism you can keep using long after you've finished it.
