Maemo is a software platform originally developed by Nokia, now developed by the community, for smartphones and Internet tablets. The platform comprises both the Maemo operating system and SDK. Maemo played a key role in Nokia's strategy to compete with Apple and Android, and that strategy failed for complex, institutional and strategic reasons. Maemo is mostly based on open-source code and has been developed by Maemo Devices within Nokia in collaboration with many open-source projects such as the Linux kernel, Debian, and GNOME. Maemo is based on Debian and draws much of its GUI, frameworks, and libraries from the GNOME project. It uses the Matchbox window manager and the GTK-based Hildon framework as its GUI and application framework. The user interface in Maemo 4 is similar to many hand-held interfaces and features a "home" screen, from which all applications and settings are accessed. The home screen is divided into areas for launching applications, a menu bar, and a large customizable area that can display information such as an RSS reader, Internet radio player, and Google search box. The Maemo 5 user interface is slightly different; the menu bar and info area are consolidated to the top of the display, and the four desktops can be customized with shortcuts and widgets. At the Mobile World Congress in February 2010, it was announced that the Maemo project would be merging with Moblin to create the MeeGo mobile software platform. Despite that, the Maemo community continued to be active, and in late 2012 Nokia began transferring Maemo ownership to the Hildon Foundation, which was replaced by a German association Maemo Community e.V. Since 2017, a new release called Maemo Leste is in development which is based on Devuan. User Interface OS2005–OS2008 Up to Maemo 4 (AKA OS2008), the default screen is the "Home" screen — the central point from which all applications and settings are accessed. The Home Screen is divided into the following areas: Vertically down the left hand side of the screen is the taskbar, with applets for the web browser, communications, and application menu by default. These can be modified using third party plug-ins (e.g. to provide a favorites or command menu). Horizontally across the top left half is the menu bar, which shows the application name and window title, and gives access to the application's menu (which contains the typical file, edit, view, tools, etc., menus and sub-menus).
