Tomato Planes vs marrow

Tomato Planes is private pilot ground school, rebuilt around one goal: understanding. Not rote memorization. Every lesson is interactive, every concept is taught in the order that makes it click, and the hard ideas come with hands-on visuals you can actually fly. WHAT'S INSIDE • A complete private pilot ground school curriculum in short, game-like lessons • Interactive visuals: bend the airflow over a wing, load a real CG envelope, ride the four-stroke cycle, fly the traffic pattern, watch a thunderstorm build • Quizzes woven into every lesson so you find out immediately whether it stuck • A skill tree that unlocks section by section, from aerodynamics through weather, performance, airspace, and navigation • Streaks, achievements, and progress tracking that make showing up easy WHO IT'S FOR • Student pilots who want their ground knowledge to actually make sense • Licensed pilots knocking the rust off • Anyone who has ever wondered how flying really works THE HONEST PART Tomato Planes is a study supplement. It will not replace your flight instructor or an official FAA course, and we do not pretend otherwise. What it will do is make your time with both dramatically more productive, because you will arrive already understanding the why. Built by a working flight instructor who got tired of watching students memorize answers they did not understand. FREE TO START The first lessons are free. Premium unlocks the full course.

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.
