Galactic Compass 2: now with new augmented reality mode

Galactic Compass 2, an iPhone app that displays a floating arrow pointing toward the center of the Milky Way, has been updated with augmented reality mode allowing users to place and walk around the arrow in their physical environment, plus a new Apple Watch app. The original app became unexpectedly popular in 2024, resonating with users who found comfort in contemplating the galaxy's center as a fixed point in the universe. The developer used AI assistance to build the app, including having Claude create its own 3D graphics library to enable the Apple Watch version.
