sndflo is a sleep-sound mixer with one thing no other sleep app has: when your bedtime story ends, the sounds don't stop. Most sleep apps end the story and drop you into silence — right when you're closest to sleep. sndflo fades the narration out and keeps your sound mix playing all night, or until your timer runs out. BUILD YOUR OWN MIX Layer as many sounds as you like, each with its own volume. Rain and a box fan. Brown noise and a campfire. Ocean waves and gentle wind. Instead of one fixed track, you build the exact bed that puts you under — and save it to load again in one tap. THE LIBRARY • Noise colors — brown, pink, white • Nature — rain, heavy rain, ocean, crashing waves, thunderstorm, waterfall, babbling brook, wind, heavy wind, crickets, campfire • Textures — box fan, airplane cabin, vacuum hum, city street, wind chimes, train, heartbeat, singing bowl BEDTIME STORIES THAT HAND OFF TO YOUR MIX Pick a calm, slow bedtime story. It plays over your sounds, and when it ends the voice fades away while your mix keeps going. No gap, no silence, no waking at 2am. MORE • Binaural beats — delta through beta • Bass and treble to shape any sound • Sleep timers with a gentle fade-out, or leave it running all night • Save and name your favorite mixes SIMPLE PRICING Free every night, no account and no trial: the full mixer, binaural beats, sleep timers, two saved mixes, seven sounds (brown noise, white noise, rain, ocean waves, thunderstorm, box fan and campfire), and five bedtime stories — including one in French and one in Spanish. Unlock once for $19.99 and get all 22 sounds, all 11 bedtime stories, and unlimited saved mixes. New sounds and stories are added over time and your unlock includes them — no packs, no upgrades, no subscription. Family Sharing is on, so one purchase covers your whole household.

Everything else carries forward from 1.1 and is still accurate: subtitle, keywords, description, screenshots, and the App Review Notes. 1.1.1 changes no counts, no pricing, no features — it only fixes playback behaviour, so nothing in the store copy becomes wrong. Fixes a problem where pausing during a bedtime story could leave the story playing, or make it stutter when you started again. The play button now also works when a story is playing on its own, with no sounds turned on.
