STS - Soft Starter Simulation is an Android application developed by Siemens AG. This free utility and tools app is designed to help users find the right Siemens soft starter for their specific application. With STS, users can simulate a soft starter application based on their input data, including environment and supply, motor, load, starting parameters, additional functions, and starting profile.

The app also allows users to select a suggested soft starter and generate a report with a summary of the simulation and optional feeder main components. Additionally, users can directly access selected soft starter data in the Siemens Industry Mall. STS supports metrics in SI and Imperial units and offers multiple language options including English, German, Chinese, French, Spanish, Portuguese, Turkish, Czech, Italian, and Russian.

STS App is continuously improved and updated to match the desktop version. For more information and to download the app, please visit the Siemens support website. Please note that the app requires an up-to-date operating system as Siemens provides updates for the latest versions. Older operating system versions may no longer be supported.
