NIX1 HD app for iPhone and iPad

NIX1 HD is a beautiful and detailed highly-realistic Nixie clock for the iPhone and iPad.

Cold-cathode display tubes, or "Nixie" tubes as they are often called, are glow-discharge indicators common throughout the cold-war era in electronic and computer display systems. Unlike simple neon lamps, Nixies can display one of a number of selectable digits or symbols. The nickname "Nixie" comes from a label on one of the early experimental tubes— NIX1, for "Numerical Indicator Experimental 1".

One of the largest and most beautiful of the Nixie tubes was the Soviet-made IN-18, which had digits 40mm (1.57") high. In more recent times, attractive and evocative display clocks are made using these vintage tubes and the companion CT-IN-18 colon tubes.

Features carefully-researched, high-resolution recreations of original Nixie tubes, complete with animated cross-fading, highlights, and accurate inter-tube reflections; configurable colon and digit settings (fade duration, blinking, 12/24 hour time, etc.); optional disabling of the auto-lock (always, or only when plugged in) for use as a desk, bedside, or wall display clock; and three colours of Nixie tubes to choose from (amber, ruby, and noir). The settings icons come up with a single tap anywhere on the clock.
