Nightly was an iOS and Android application, developed by DreamJay company, which was meant to help in sleeping - by showing soothing videos and playing relaxing music during falling asleep, then playing very soft reminiscences during REM phase, finally waking up the user by playing soft alarm clock.

 

Ryterski was not only composing music within certain restrictions and guidelines, but he was also doing research, mixing, mastering for the phone speakers. He was also working with other people, developing new ideas for the video-music themes. Ryterski was part of the team in years 2017-2018, up until the company was closed.
