CylinderBoss was originally created for Auckland testing station Global Dive to replace the paper based test sheets that were time-consuming to fill in.

After New Zealand certification body NZUA approved it for official record keeping and recommended that every test station should be using it, CylinderBoss was launched as a Software-as-a-Service productivity tool.

What began in 2018 as a simple digital form for one test station, developed into a fully integrated cylinder testing tool that takes care of creating and archiving test certificates as well as communication with clients and data integration with in-house point-of-sale and accounting systems.
