OS Cleaner Master is a system maintenance tool that offers to clean up your computer of useless files in order to reclaim valuable free space. In addition, it allows you to check your CPU usage, monitor the network traffic and free RAM memory.

The program has two display modes. On the one hand, it opens with a classic window-like interface allowing you to scan for junk files that can be removed selectively. On the other hand, the app has a menu bar icon-like representation that lets you monitor important system issues, such as memory consumption, CPU usage, and traffic analysis.

As a system optimizer, the tool performs a fast scan in search of junk files. The results are structured into clearly defined categories of files, caches, logs, broken login items and files existing in the Trash bin. Each identified item can be previewed and revealed in Finder, so you can decide whether it's worth being deleted or preserved. However, the program includes a series of advanced optimization features that you need to pay for in order to make them fully functional - namely, you can purchase the advanced cleaning up module, the file managing section and the system utilities unit.

As a system monitoring tool, the program measures the time since the last system boot and informs you about the computer startup time. In addition, you are provided with real-time information about RAM usage, CPU performance, and incoming and outgoing traffic. If memory consumption reaches a risky level, you can ask the program to instantly free up RAM memory.

To sum up, the free version of OS Cleaner Master is a mere presentation of a full-featured system maintenance tool that includes advanced computer performance optimizing techniques that need to be purchased.
