A retro mainframe for your iPhone: live CRT monitor in glowing green or amber phosphor, a home screen widget and classic games.

Turn your iPhone into a mainframe from the golden age of computing.

MAINFRAME MONITOR shows your device's live stats wrapped in a nostalgic CRT console – complete with phosphor glow, scanlines, a boot sequence and satisfying key clicks. Choose between classic GREEN or warm AMBER, each with its own matching app icon.
