Highlights
  • Focus timer with deep-space progression
  • Cosmic discoveries collected over time
  • Star chart and journal views
  • Genesis trees that grow from sessions

Voyage is a quiet deep-space companion. A small vessel travels even while the app is closed. When it arrives, one notification calls you back to uncover a real astronomical object. Choose a short, long, or deep voyage. There is nothing to keep running and no deadline to meet: the ship waits for you at the other end. Every arrival adds to a growing record of the universe, to read, revisit, and trace across your star chart. A voyage can also retrace a real mission. Historic Adventures follow a recorded path leg by leg: Voyager 1 from Jupiter to interstellar space, Huygens falling to Titan. Every leg arrives at something that happened, with the sources it came from. Both are free to follow. There are no streaks, leaderboards, or daily tasks. Nothing asks you to come back. Features: - Voyages that continue while the app is closed - Historic Adventures that retrace real missions, leg by leg - Real astronomical objects with hand-written stories, encounters, and questions - An evolving journal and star chart - A learnable alien voyage clock - An ambient travel scene and music - An Apple Watch companion showing the voyage in flight - Genesis trees shaped by recovered matter - Optional Signal Beacons from other voyagers - No account required, and core exploration works offline - Free to start, with an optional one-time unlock

Space is your racetrack. Gravity keeps changing the rules. Run across a luminous spacetime grid in a physics-inspired arcade adventure. Start with Einstein and rescue more scientists through gameplay, mastering their abilities along the way. Swipe between lanes, leap over rifts and slide beneath obstacles as the pace builds. RESCUE THE SCIENTISTS Start with Albert Einstein and unlock three more scientists through gameplay: Albert Einstein - Dash: Race forward with a protected lightspeed burst. Hugh Everett - Portal: Open a shortcut and jump ahead along the course. Marie Curie - Extend: Double the remaining time of your active power-ups with two free uses each run. Unlock a permanent third use for 5,000 Quanta. J. Robert Oppenheimer - Nuclear strike: Launch a missile that clears nearby obstacles with an expanding blast. Choose your scientist, master their ability and push your personal best farther. Preview characters and outfits in the Wardrobe and choose your field equipment. NEWTON'S CITADEL Once all four original scientists are rescued, enter a new chapter beneath a blood-red eclipse. Reach Newton's castle, break the seals holding Tesla, and escape across a twisting road pursued by Newton and a looming creature. Collect three portal keys, survive the final barrage, and bring Tesla through the breach. Unlock Tesla and his coil staff, which any scientist can equip for four uses per normal run to clear obstacles and repair broken road. A CHANGING COSMIC COURSE Navigate narrowing wormholes, gravity bends, asteroid showers and cosmic-string obstacles. Choose a multiverse path and watch the road climb into a different landscape. Race through black-hole encounters beneath a moving universe of stars. GADGETS FOR THE NEXT CLOSE CALL Draw in Quanta with the Magnetar and protect a run with a Quantum shield. Use your scientist's ability when the course gets dangerous, and use earned Quanta to upgrade your equipment.
