Nixie Tube Timer

Down to 30 seconds and need longer? Tap +1m and the clock reads 1:30, still running. Photorealistic nixie tubes, eight color themes, fully offline, nothing tracked. A TIMER YOU ACTUALLY WANT TO LOOK AT This is a countdown built around photorealistic nixie-tube digits. Dial in hours, minutes and seconds, hit Start, and watch the tubes glow down one digit at a time β a focus sprint, a kid's timeout, a pot on the stove. The screen stays awake while it runs. STRETCH A TIMER THAT'S ALREADY RUNNING This is the part other timers don't do. You set one minute. It counts down to thirty seconds and you realize you need longer. Tap +1m and the clock reads 1:30 and keeps going β still running, never stopped, never reset, nothing to start over. EIGHT COLOR SCHEMES Neon Green, Cyber Blue, Amber Glow, Crimson Red, Deep Purple, Hot Pink, Sunny Yellow and Rainbow. Switch instantly, no restart. A Full Glow style spreads the aura across the whole screen if you want more of it. SOUND ON YOUR TERMS Six tick sounds β Classic, Soft, Digital, Woodblock, Mechanical, Pendulum β synthesized on the fly and locked in step with the digits. Four alarms: Radar, Beacon, Chime, Pulse. Import your own audio file as a custom alarm, or set either to None for silence. Ticks and alarm have their own volume sliders. THE BUTTONS ARE YOURS The amounts you add are the ones you choose β +30s, +1m, +5m, +25m, whatever your day actually uses. Nothing is preset for you; press and hold to remove one. They sit right under the countdown while it runs, one tap from the tubes. Durations you run often come back as one-tap shortcuts too. BUILT TO BE QUICK - Timers from a few seconds up to 99:59:59 - Timed against the clock, so it stays accurate instead of drifting - Pause, resume, restart, cancel β or stretch the countdown without pausing it - Haptic feedback on start, on tap, and at zero - A local notification when the timer ends, even if you have left the app PRIVACY, PROPERLY No accounts, no ads, no analytics, no tracking, no data collection of any kind. The app never sends anything anywhere. Everything you set stays on your device. Free. iPhone, iOS 17 and later.
