Unspin is a free, step-by-step coach for the Epley maneuver, a common canalith repositioning routine used when someone has BPPV-related spinning vertigo. It guides you through each head and body position with clear on-screen steps, uses your phone’s motion sensors (on-device only) to help coach head position, and works without an account, camera, or internet connection. Educational only, not medical advice. Publisher: Ryan Moalemi, https://ryanmoalemi.app
