The calculation program on our website provides an approximate calculation of the spring required for your application. This is purely indicative, as the calculations for the finished product require a complex software system which goes much further.
The Institute of Spring Technology (IST) supplies this kind of software. They have taken the initiative to develop an easy-to-operate app for the iPad. This free software allows you to make exact calculations to design your spring entirely according to specification. Unfortunately, the app is currently limited to compression springs, but this will no doubt be expanded in the future.
The app is available for the iPad. You can find it in the App Store:
