marrow is a feed of ideas worth keeping. Instead of an endless scroll of noise, you move through short, self-contained explanations (one concept per screen) across computer science, finance, math, and science. Each card explains a single idea in a few sentences: why appending to a dynamic array is O(1) on average, what the Rule of 72 estimates, and dozens more. Some cards ask you a question first. Reveal the answer, then tell marrow how well you knew it. The ones you find hard come back sooner; the ones you already know drift further out. That is spaced repetition, built into the scroll, so the ideas you want to keep actually stick. - One idea per screen, made for short sessions - Four domains: computer science, finance, math, and science - Self-grading with spaced repetition, so reviews return at the right time - Fully offline: no account, no ads, no tracking. Your progress stays on your device. Scroll to learn.
