I want to create an iOS app that is a simple todo list and journal app.

The todo and journal aren't two separate things.
User types or talks to the app.
User tells the app what their priorities or todos are and chats, talks about their day and what they got done.
They tell the app what they got done and what they are working on.

The app in the background is creating checklists and prioritizing based on the conversation with the user.
The app will use a cheap version of an AI LLM and needs a way to keep context of the day, week and month.

User should be able to make any changes and tell the chat conversation that they completed something and the LLM knows to mark it complete.
The AI LLM is to ask simple questions if it doesn't know if the task is recurring or a one off and if there is a certain priority.

If the user says they completed something it needs to show that it was marked as complete. All of this happens within the chat.
There is a page that shows all the items and a journal of each day's conversations and summary of completed items.

I need you to ask me questions and interview me so we can create a PRD to build this app. Remember this is a minimalistic and simple app.
