Short answer
Sereno's Nursery sounds include womb (a low-frequency rhythmic rumble), a shush (rhythmic modulated pink noise), and heartbeat — three sounds commonly used by caregivers for newborn soothing. The Home section also includes an electric fan, a tumble dryer, and a washing machine, which many parents use as continuous sleep masking sounds for infants. Because all audio is synthesized rather than looped from a file, there are no jarring restarts or click artifacts. Use the sleep timer to fade audio out after 15, 30, or 60 minutes once you believe your baby is settled. One Pro purchase unlocks all Nursery and Home sounds permanently. Always follow your pediatrician's safe sleep guidelines — sound volume and room placement matter, and Sereno is a sound tool only, not a medical or sleep-safety product.
Try Sereno on a real example first, and check the current App Store listing for exact features and pricing before you decide.

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
