v1 and v2: what's the difference



Spring Calculator Professional v2 was a major upgrade released in 2019. Its purpose is to fully utilise the latest in programming technology and security to ensure its longevity and offer features we otherwise would not be able to.


Since its launch, we have continually developed SCP v2 by adding features that make the software easier to use and an asset to all design engineers, spring manufacturers and end-users. 

If you are using SCP v1, we highly recommend upgrading.  Support for anyone using v1 will no longer be available towards the end of this year (2021).
