WHAT IS INSIDE

— A detailed encyclopedia of the eight planets of our solar system with distance, diameter, orbital period, rotation, temperature, mass and key facts. Bookmark your favorites and share a planet summary with one tap.

— A catalogue of cosmic elements, from hydrogen to silicon, with atomic data, state, melting and boiling points and a fun fact for each. Create your own custom element cards and delete them at any time.

— A Fusion workbench where you combine two elements on the bench and discover cosmic results: helium, water, methane, silicate, iron oxide, rocky planet core, main sequence star, red giant and more. A locked gallery shows the recipes you have yet to discover.

— A space calculator with three modes: light-year to kilometer, astronomical unit and parsec conversion; weight across all planets, the Moon and the Sun; and a travel-time tool that simulates journeys at a fraction of the speed of light.

— A term-matching quiz with easy, medium and hard difficulty, featuring supernova, light year, pulsar, black hole, dark energy, nebula and more. Green and red feedback, pause modal, perfect-score screen.

— Rocket Voyage, a 20-level arcade where you steer your rocket with left and right buttons and catch cosmic objects while avoiding hostile creatures. Difficulty, speed and spawn rate scale across levels. Hearts, score tracking and personal best are saved.

— Planet Dodger, a 50-level flight game. Hold the button to thrust upward, release to fall, and weave through planet-sized obstacles streaming in from deep space. Progress, best level and achievements are persisted.

— A themed shop of space gear with category filters, search, product details, quantity control and a cart. Checkout is cash on delivery only, with a short delivery form, order summary and a confirmation screen listing the amount due to the courier.

— A built-in support chat reachable from the shop. Ask about orders, payment, bonuses or returns and get an instant reply, with quick-reply chips to start a conversation.

— A bonus card with a personal shareable code, a redeemable promo code field and twelve achievements tied to in-app actions. Every completed mission, flown level, saved planet or placed order brings you closer to the next reward.
