Galactic Compass 2 adds AR mode: point your iPhone at the Milky Way's core

Galactic Compass 2: now with new augmented reality mode

Matt Webb's Galactic Compass app, which points to the center of the Milky Way, gets a major update with augmented reality and an Apple Watch companion. Version 2 lets you place the arrow in the real world and walk around it, while the watch app provides haptic feedback. Webb shares the making-of, including how he used AI to finally grasp quaternions and how Claude Fable built a custom 3D library for watchOS.
