From 3.5 billion Reddit comments

Accompanying doing past papers, I've found some pretty helpful apps that goes with Physics and Economics. Felt like they're worth a share!

Econ: https://play.google.com/store/apps/details?id=economics.ib

The notes are concise yet extremely comprehensive at the same time. The developer organized notes by subtopics corresponding to the syllabus so it makes sure you learn everything you will need for the exams (at least on the basics). Worth checking out!
