Night Knight is a Noise Machine, a Night Light, and a Wake Aid that changes color at wake time. Designed to be as delightful and simple as can be, as well as not distracting for potential little humans that might be sleeping close to it. ∙ Noise Machine: A single tap plays (White | Brown | Pink) noise, all through the night. ∙ Night Light: Turn your device into a calm and soothing night light with a configurable ring of light around the edges of the screen, which can be tweaked in intensity and color. ∙ Wake Aid: Set a timer, or a time of day for the white noise to stop and or the Night Light to change colors, ideal for the little ones that need to know if it’s time to “leave the room” or not. This app was built when I was traveling with my family and realized we’d forgotten our kids’ night light. Ideal to use on the go on iPhone or iPad. Don’t forget to plug in your device to power if you’re planning to leave it running all through the night.
