Apex launcher is a nice customization app with the help of which you can customize your smart phone very easily. Its available on google play store which can be download easily to your android mobile. I downloaded it last month and really liked it.
It has many customization options. By using them you can give your android mobile a full makeover. It has some amazing transition effects while scrolling your home screen or app drawer. You can make shortcuts of your most used apps to home screen and also change icons of shortcuts and folders.
You can sort app drawer of your mobile according to install date or alphabetically. After you customize your mobile desktop according to you need you can lock the desktop to prevent any accidental change. You can also change the style of app drawer to horizontal, vertical, or paginated. So I have a good experience using apex launcher.
