IBR’s Zulu Smartwatch and Zulu Data Extractor App are used for general sleep and activity tracking, which allows users to connect by Bluetooth and download .csv data directly from their Zulu Smartwatch. The Zulu Data Extractor App can be used by individuals who want to download their own sleep history or by organizations collecting sleep data from their employee base. The Zulu Data Extractor will download a zip file from the Zulu Smartwatch, containing one .csv file with up to 80 sleep events and another 1-8 .csv files containing 2-minute epoch-by-epoch data for the previous eight days. The zip folder can be shared to any email and be directly imported in IBR’s bio-mathematical fatigue modeling software.”
