About Open Qstat

Who we are

Open Qstat is run by Qlabs, the developer of the desktop statistical analysis program Qstat. We brought Qstat's most-used chart features to the web so they work exactly the same way: the chart style, options, statistics and automatic interpretation all match the desktop program.
