Sleep Train is a calm night train game: one dad's journey, made into a timer app. This is my story — how it felt to stay steady for my family on long nights. An interactive love story you can open as a quiet ride: Learning waits, Loving check-ins, and open-ended Letting under the moon. In the morning, a simple report remembers the night as presence, not a score. WHAT IT IS • A portrait, phone-first night ride with ambient music and cabin sound • A gentle timer you can pause; progress stops if you leave the app • Optional vibration and phase music (turn either off anytime) • Easy mode for shorter practice waits, or Normal for a full night's pacing • Preferences and history stay on this device only — no account, no ads WHAT IT IS NOT Sleep Train is not a baby sleep-training program, not medical advice, not a treatment plan, and not a promise about anyone's sleep. Always consult your pediatrician about your child's health. Developer: Dr. Kris Alexander / The Digital Citadel Privacy: https://videogamesprof.github.io/sleeptrain-privacy/
