We at Gylling Data Management (GDM) create, market, and support ARM software for managing and summarizing agriculture research experiments.

  • ARM saves time creating trials, analyzing data, and producing the many reports required for successful and timely trial management.

  • ARM is a recognized and respected standard throughout the crop production and protection industry.

  • ARM is used by thousands of researchers in 75 countries worldwide (more than any other integrated research trial management software).




ARM 2015 Release

Planned ARM 2015 release date is beginning of November 2014, to use for the 2015 field season.

The "ARM 2015" name identifies this ARM version as prepared for the 2015 field season. ARM 2015 contains all features of ARM 9.2014, plus many new features. (ARM 2015 was previously referred to by its internal "10" version number.)
  • New ARM 2015 orders will ship as ARM 9.2014, and will automatically upgrade when ARM 2015 is released.
  • ARM Feature Comparison (pdf) gives an overview of ARM 2015 features compared to previous
    ARM versions.
  • See ARM 2015 FAQ for details on ARM 2015 questions, also support and upgrade changes.
  • See an ARM 2015 Overview (pdf) of new features, as of September 2014. We will update this presentation periodically until ARM 2015 is released.
  • Use the Write to Us page to ask additional questions or request a price list.
  • GDM continues our policy that the most economical time to upgrade is always when a new version is first released.
  • For contract researchers, ARM 2015 fully supports all sponsor customizations and ARM versions, and will provide sponsors with better quality trials than previous ARM versions.
  • Remember ARM 8 End-Of-Life is December 31, 2014. Upgrade now while a reduced price is available.
