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
