Hi Product Hunt! I'm Ryo, a solo developer in Japan. When my son was a newborn, he cried through the nights. A little white-noise speaker got us through, and that's where Kumofuton came from. I wanted a sleep-sound app that does one thing well: play a steady, seamless sound until morning and never wake anyone. - 27 sounds, all free: real CC0 field recordings (rain, waves, fire), white/pink/brown noise, and household sounds for babies (kitchen fan, washing machine, hair dryer, the womb) - Long, seamless loops, so nothing starts over in the night - Layer up to two more sounds - A wake-up alarm that rings even in Silent mode on iOS 26 (AlarmKit) - A calm cloud-and-stars look that stays dim at night - No ads, no account, no tracking Kumofuton Plus is an optional one-time purchase for longer timers and more alarms. No subscription. I'd love to hear which sounds help you or your little one sleep.
