Marrow is a feed of short concept cards across computer science, finance, math, and science. Scroll to read; reveal answers and grade yourself so spaced repetition brings the ideas worth keeping back around.
How do I use it?
Scroll vertically through the feed. Some cards ask a question first. Tap to reveal the answer, then choose how well you knew it. Cards you find hard return sooner.
Where is my progress stored?
Entirely on your device. Marrow has no account and sends no data anywhere. Deleting the app removes your progress.
