# Test on Simulator

Kalipso has an integrated Simulator where you can test your applications before deploying it to a mobile device. This feature helps you to be more productive while creating your applications. Kalipso Simulator is the same framework that runs your applications on a mobile device, compiled for Windows 32, which guaranties that your application is executed the same way that on a mobile device, except for some clearly marked Actions that only work on specific platforms.

* **Erase Data on Simulator** - If you check this option, it means that before integrating your Project, Kalipso will clear it from the Simulator as if never existed, including data.
* **Run Again** - allow to run the project again without saving or making a new deployment. Useful if there was any change to the project and it's faster to launch.
* **Trace Actions** - This option allows you to debug your Project, by showing you all the Actions being executed as well as their parameters values.
* **Trace Variables** - This option allows you to to trace the content of the variables in runtime.

Combine these features with the ["Breakpoint](/kalipso/documentation/actions/group-code-flow/breakpoint.md)" Action to run your Project step by step.
