The X launcher comprises of lined-up tiles. However, you can add folders if you're overwhelmed by apps. Despite being an Android device, the phone maintains the looks and feels of a Nokia device. The X also features a notification menu off to the side called Fastlane (a familiar terms for N9 and Asha users), giving you information regarding your favorite/most-used apps, your activities, open apps and background processes.
