Many Android themes aren't too elegant, particularly those included by default on many handsets. Themer, however, manages to surface the best with a voting system, allowing its members to favourite themes they particularly like. The result is that the most innovative, interesting and intelligent rise to the top.
Themer allows users to switch between different homescreens with one click, browsing through a user-generated database of themes to find the one that best suits their needs.
Themer deals with the wide range of apps used by Android users. Instead of including icons for Pandora, Spotify, Google Play Music and so on, theme-creators instead just include a music icon. The first time you press that, it'll ask you which of the music apps installed you'd like to use. From then on, whichever theme you install will open that app.
