Solar Monolith is a calm, self-paced learning app about our Solar System, guiding you from the basics of the Sun's role as the system's engine all the way to the fundamentals of mission design. No clutter, no ads shouting for attention — just structured lessons, practice, and a personal notebook.
The app is built around ten short lessons, each five to eight minutes long: why planets don't fly off into space, how rocky worlds from Mercury to Mars compare, what asteroids reveal about the system's history, how gas and ice giants differ, and how tidal forces shape oceans and geology. Every lesson shows its topic and estimated time, and your progress saves automatically as you go.
The practice section offers scenario-based multiple-choice questions that test real understanding of gravity, orbits, and planetary physics rather than simple memorization. A built-in glossary collects key terms — orbit, gravity, spectrum, greenhouse effect, asteroid belt, and more — with clear definitions you can save for later review.
For learners who like to keep notes, a dedicated notebook lets you jot down observations, questions from a lesson, or facts worth remembering. The progress screen ties it all together, showing lesson completion, your best practice score, a review queue of saved material, and your note count, with an option to reset local progress and start fresh anytime.
Everything is stored locally on your device — no accounts, no cloud sync, no distracting ads. Solar Monolith is a great fit for students, curious learners, and anyone who wants to understand how our Solar System works, at their own pace.
