Hushr is a free iPhone app developed by Jan Peter Peschlow that aims to help calm down babies and aid in their sleep. The app offers a variety of white noise sounds that have been proven to soothe infants and create a comforting environment for them.

Newborns are accustomed to high levels of noise from inside the womb, so when they become anxious or cry, playing steady sounds can help calm them down. Hushr provides a range of sounds, including hair dryer, womb, and vacuum cleaner sounds, among others. Parents can try out different sounds to see which one their child responds to best. Each sound comes with two variations - softer, smoother sounds for sleep and louder, more intense variations for crying.

One of the standout features of Hushr is that sound playback continues even when the iPhone is muted, ensuring no disturbances from ringtones or message sounds. The app also allows users to add their own recordings or import recordings from Apple's memos app to play with a sleep timer in a loop.

Hushr offers a flexible nightlight screen with different color schemes for light and dark mode. Users can choose between colors using gestures, adjust the brightness of the light and screen, and apply a color mask for a realistic light appearance. The app also allows users to change the order of the sounds, create a favorites list, and make full use of the app's functionality through swipe gestures and 3D touch, including the ability to start or stop playback by shaking the iPhone.

Overall, Hushr provides a convenient and effective solution for parents looking to calm their babies and help them sleep. With its wide range of white noise sounds and additional features like the sleep timer and customizable nightlight, Hushr offers a comprehensive solution for parents in need of a reliable tool to soothe their little ones.
