Todoist

If Notion feels a little too broad for what you need, Todoist is a great middle ground. It’s one of the easiest productivity apps for new iPhone users to understand because it focuses on what most people actually need: tasks, planning, and simple organization. 

Overall, Todoist is the best of two worlds. It feels more structured than a simple note-taking app, but it’s still simple enough that anyone can just pick it up and start using it without a long tutorial beforehand.

You can use it for grocery lists, work deadlines, recurring chores, school assignments, or longer-term goals without feeling like you’re running a whole business dashboard from your phone. Of course, if you want, you can also use it to run more complex projects, and even share them with other users, so everyone knows what they should be doing and update their progress, without having to micro-manage everything yourself.
