About

EVA Clock Nixie

Features
Read full description

A nixie tube clock for your iPhone or iPad. The glowing orange digits are not photographs. Every bend of every numeral, and every wire stacked behind it, is drawn from scratch. Each digit is built as a single bent wire, and three layers - bloom, midtone, and glowing core - stack up to make that particular orange light. The digits that are not lit are still there, as a faint stack of ten numeral-shaped cathodes behind the glowing one. As the time changes, lit and unlit tubes quietly trade places. Turn the device sideways and the tubes fill the screen. It is meant to sit on your nightstand or desk as the clock itself. WHAT IT DOES - Home Screen widgets showing hours and minutes, in a small square or a wide rectangle - they work in StandBy too - Switch between 12-hour and 24-hour display - Hourly chime, with a three-second countdown tone and adjustable volume (it respects the silent switch) - Keep the screen awake while the clock is showing - Dim the display for night use - Protect OLED displays by shifting the clock a few points every few minutes ABOUT THE WIDGET It sits on your Home Screen or in StandBy. It shows hours and minutes; seconds do not move. iOS decides when widgets refresh, so the displayed time may lag slightly behind. Lock Screen widgets are not supported - the Lock Screen renders widgets without color, and nixie tubes do not survive that. USING IT Tap the screen to open the settings. There are no other buttons - you get the clock and nothing else. PRIVACY This app collects nothing. No analytics, no crash reporting, no advertising. It performs no network communication at all. Your settings are stored only on your device. REQUIREMENTS iOS 17.0 or later / iPadOS 17.0 or later Also available for Mac under the same name.
