DIESEL Pro is a recent app switcher that provides quick access to your most used and recent apps from the notification area. With this app, you can easily swipe through your last apps from anywhere, allowing for multitasking and launching apps quickly. Unlike other app switchers, DIESEL Pro operates from the notification area, which means no background service is running all the time.

One of the best features of DIESEL Pro is its customization options. You can set the mode to recent apps switcher or most used app switcher, as well as whitelist apps. Additionally, there are many customization options available, such as icon pack support, unique icon shapes, and the ability to change the number of shortcuts, icon color, icon size, and background.

DIESEL Pro is fully compatible with Android 4 or greater and is similar to HTC Sense's recent apps. It is perfect for those who want to keep their home screen as clean as possible while having quick access to their most used and recent apps. Overall, DIESEL Pro is a great app switcher that is easy to use and highly customizable.
