One song. On repeat.
Every night, my kid wants the exact same lullaby. Not a playlist. Not a library. Just that one song, starting the moment I open the app. I built One Song because nothing else did exactly that.

People use it for bedtime lullabies, rain sounds looped through the night, and that one track they can't stop listening to. The sleep timer handles the rest.
Every night before bed, my kid wants to hear the exact same lullaby. We used to play it on YouTube — navigating through UI clutter, playlists, and multiple taps just to get to the one song we needed. I wanted an app that opens and plays. That's it. One Song is that app.
