In an era of subscription SaaS and bloated software, Gradistat v 9.1 represents a perfect artifact of pragmatic, open (though not open-source) scientific computing. It does one thing and does it well: converting messy sieve and hydrometer data into interpretable sediment statistics.
If you used physical sieves, gather the aperture sizes in millimeters or phi (

The software automatically calculates the cumulative curve, sorting statistics, and mean size.
Because GradiStat was released as a free tool by its authors to support the scientific community, no paid license is required. However, obtaining a legitimate copy of the original file can sometimes be challenging, as the developers have moved on to a "Pro" version.
