She writes the list, he ticks it off
Kılıbık connects two phones. One of you takes the Prenses role and sets the tasks; the other takes the Erkek role and marks them done. Nothing more, nothing to configure — a shared list with a sense of humour about who is in charge.
When a new task is created, the phone it was assigned to gets a push notification. That is the only notification the app sends — there is no marketing, no reminder spam and no daily digest.
A task is visible to the person who wrote it and the person it was given to. Nobody else can read it, and the app has no way to browse other users or search for them — the only route to a pairing is a code that someone hands you.
Either side can end the pairing at any time. When they do, every task between the two is deleted for both of them.
