Read full description

There are only 10 types of people in this world: those who understand binary and those who don't. Binary O'Clock is a glowing binary clock for your iPhone, iPad and Apple Watch. Six columns of LEDs show the time as hours, minutes and seconds, ticking away in ones and zeros. HOW TO READ IT Each column is one digit of the time: HH MM SS. Read each column from the bottom up. The LEDs are worth 1, 2, 4 and 8, so add up the ones that are lit to get the digit. For example, a column with the 2 and 4 LEDs lit shows 6. FEATURES • Full-screen 24-hour clock with hours, minutes and seconds • Widgets for the Home Screen, Lock Screen and StandBy • An Apple Watch app, and complications for your watch face • Keeps the screen on while the clock is showing • No ads, no accounts, no data collected BINARY O'CLOCK PRO Tap the clock to open Settings, and try any of it first: a live preview shows your clock before you buy. A one-time purchase unlocks, on Apple TV, Mac, iPad, iPhone and Apple Watch alike: • Themes: White, Aviation green, and Dust, with dark dots on sand • Round LEDs • Learning mode: shows what each LED is worth and the number in each column • 12-hour time • A speaking clock: touch and hold the clock to hear "14:32 and 20 seconds", then a beep exactly on the second No subscription. The classic blue clock stays free, widgets and complications included. Also on Apple TV and Mac. Perfect on the nightstand in StandBy, on your wrist, or as a daily brain teaser for anyone learning binary.
