Soothing sounds, bedtime stories and sleep tips with sources, for babies and toddlers from 0 to 3 years.
Hertz, a sleepy koala, guides you every night.
Womb, heartbeat, white, pink and brown noise, rain, ocean, lullabies and classical music, plus a timer that fades out gently.
8 original bedtime stories of about 10 minutes each, with 4 voices to choose from.
84 sleep tips for every age, based on pediatric guidance and published studies. Hertz reads them aloud.
Sing lullabies with the music and lyrics on screen, and the app records your voice. Or record a goodnight message.
Guided sessions, a sleep log with 7, 15 and 30-day trends and personalized ideas, and reminders that can ring as an alarm.
A warm night light for night feeds and one minute of calm breathing for you.
