QKSMS is an open source application. It has a simple interface and is useful. You can reach all options by tapping the button with three points. Change theme from settings; color, and other options. Do not include ads or in-app purchases.
Only the theme color changes in settings. It's just plain color making the application boring. My suggestion is to add any desired official background.
The theme of using the application is simple and tedious. it is possible to have more fun and useful by adding special images to the theme. I believe that qksms users will love and recommend.
