Neybox

Neybox is a European app development studio based in Nicosia, Cyprus that includes a small remote team that aims to combine technological innovation with great user experience to enhance the well-being of individuals. Neybox was founded in 2016 by Panos Spiliotis and Spyros Passas.

Neybox developed Pillow, a free sleep tracker app that records periods of activity at night and provides an analysis of sleep. Pillow can record audio and heart rate data and provides information on periods of waking, REM, light sleep, and deep sleep, using a color graphic. The premium version, which is not free, includes the feature of audio recording, snooze lab recommendations, detailed sleep history, and a "powernap" mode that guides users through one of three short naps.

Use with an Apple Watch improves the function of the app, but is not necessary. With the Apple Watch, Pillow can be launched from the wrist and the smartwatch’s gyroscope is used to track movement throughout the night for more accurate measurements. Pillow can also be used as a smart alarm. The app incorporates feedback about a user's mood, to help the user achieve optimum conditions for a good night’s rest.

Using Pillow with an iPhone is similarly accurate to use with the Apple Watch, but requires the handset to be resting on the mattress alongside the person sleeping.
