Launched in late 2018, FLO is a fairly new South Korean streaming service created by SK Telecom in cooperation with partners such as Big Hit Entertainment, JYP Entertainment, and SM Entertainment. Unlike other streaming services that reflect hourly data, the FLO chart reflects streaming data for 24 hours to prevent any unusual streaming patterns, providing a more reliable popularity chart. As of November 2019, FLO has become the third biggest streaming service in South Korea after MelOn and Genie.
FLO is only available in South Korea, and its data is not used for music shows; however, it has been added to iChart.
In order to achieve an All-Kill, you must top the FLO real-time chart as well as the other charts included in iChart.
