Full featured software

Please see our module list page for more information on what modules are available. Also please see our Frequently Asked Questions page to answer any other questions you may have.
Freedom to work anywhere
We all use multiple computers. With Daystar iStructural.com you won’t have to remember which computer has which software and where your data is stored. All calculations are stored on our servers so when you login your past calculations will be right there. If you do want to save your results to a local computer you can do that with a push of a button.
Always the latest version
You never have to check to see if you have the latest version. When we update the software you will automatically have it the next time you login.
No licensing issues
Use the software on any computer at anytime -- usage is not tied to a particular computer or network. With Daystar iStructural.com, licensing issues are a thing of the past.
