About
A study app for general chemistry — and for the college algebra it keeps assuming you already have. Every card, summary and example comes from the OpenStax textbooks themselves, so you can always follow a topic back to the section it came from; what your course tests, and when, comes from the course’s own published syllabus, and the coverage page says which kind of claim each row is.
It runs entirely in the browser and installs to a home screen, so a study session does not need a network.
