In the Telegram or MAX Mini App, open Comfort → Sounds; the chat itself has no player. In the native iOS/Android app, open Sounds from Comfort. The six built-ins are lullaby, white noise, rain, forest, savanna, and space. The current build plays one sound at a time, with volume control and an optional 15, 30, 45, 60, or 90 minute timer followed by a short fade. Linked caregivers share the child's uploaded audio and saved YouTube links. Audio files play in NapCoach; YouTube opens externally.
Good to know
Comfort requires subscription access. Mini App audio is intended to continue while the Mini App stays active, but its WebView or operating system may pause it in the background or on screen lock. Native playback is designed to continue away from the Sounds screen and while the device is locked, subject to normal system interruptions.
If it does not work
Contact @napcoach if built-ins repeatedly fail, a supported upload cannot be saved, or another family can access the library.
