StarMark Space

Fly through 8,920 real stars from the Yale Bright Star Catalog in your own pocket universe.

StarMark puts you at the controls of a genuine flythrough of the Milky Way. Every star you pass is real — named stars like Sirius, Vega, Rigel, and Arcturus appear labeled as you approach them, placed at their actual catalog positions.

EXPLORE IN THREE DIMENSIONS

Your right thumb controls speed. Your left thumb steers — left/right to turn, up/down to pitch. Push past warp speed and every star erupts into a vivid colored streak.

NAVIGATE WITH YOUR RADAR

A live color-coded radar tracks your prize star. Red when far, yellow as you close in, green when you're almost there. Steer until the dot centers — then fly straight.

REAL ASTRONOMICAL DATA

8,920 stars from the HYG/Yale catalog rendered at their correct spectral colors. Blue-white hot stars, warm orange giants, pale yellow dwarfs — all real.

BEAUTIFUL AND IMMERSIVE

A shifting five-color nebula background slowly cycles through deep purple, midnight blue, teal, crimson, and magenta as you fly. Every minute looks different.

COLLECT STAR PRIZES

Chase a glowing gold prize through the cosmos. Collect it and 16 gold particles burst outward, your phone vibrates, a chime plays, and a new prize spawns ahead.
