While it is true that Planbox is not a tool that is dedicated to SCRUM, we do adhere to the values outlined in the Agile Manifesto.
We chose not to build a SCRUM-specific tool so that it would be easier for Planbox to adapt to all kinds of environments, business types, workflows and processes.
Planbox uses iterations (Current, Next, Future) including a Backlog and Points can be used for estimates. Apart from "stories" which we call "items", SCRUM users feel at home within our tool.
