SimBooster is a Mac utility designed to help you improve the performance of your system. The application is packed with a wide range of built-in tools capable of reclaiming disk space on your drive, removing unneeded programs and files from your Mac, and so much more.
The program's interface is very intuitive and nicely designed. By clicking the 4 square button from the upper-right side of the main window you will reveal a screen showing all of the integrated tools. The app comes with a cache cleaner, a program uninstaller, a duplicate finder, etc. Each of the built-in tools features easy-to-configure settings.
Furthermore, in the Preferences panel, you will find additional settings for selecting which types of cache files to look for, various options for the cookie cleaning process, etc.
Unfortunately, the program doesn't work 100%. In my testing, the application crashed a couple of times (once, when I accessed the Startup Optimizer tool) and occasionally ran slow, especially while completing the scanning processes. Another aspect that bothered me was that the trial version of the utility didn't allow me to test all of its built-in tools. For example, you cannot uninstall any apps or delete duplicates while using the trial version of the app.
Personally, I wouldn't pay for an app that doesn't work well and doesn't let me test its capabilities before acquiring it. In my opinion, you should look for a different program for improving the performance of your system.
