About

Strange Clocks

Features
Read full description

Strange Clocks turns "what time is it?" into a small daily puzzle. Instead of one clock face, you get 15, each a different, real way humans (and machines) have told time throughout history: from a Cold War-era German clock made of lamps to the way a resistor's color bands encode a number. Every clock is stranger than the last, but none of them stay strange for long. Each one ships with a short animated guide that highlights exactly what to read and when, plus a live calculation line so you can watch the math happen in real time. WHAT'S INSIDE - 15 unusual clocks: Berlin Clock, Word Clock, Binary Clock, Cistercian Clock, Fibonacci Clock, Tix Clock, Hex Clock, Maya Clock, Moon Clock, Polar Clock, Resistor Clock, Decimal Time, Internet Time, Roman Hours, and the Prague Orloj. - An animated how-to-read guide for every single clock, no exceptions. - Widgets for Home Screen, Lock Screen, and StandBy, in small and medium sizes. - Clock Wall mode: turn your iPhone, or the inner display of iPhone Duo, into a live wall of clocks, screensaver-style. - 10 languages: English, Spanish, Simplified Chinese, Japanese, German, French, Brazilian Portuguese, Russian, Korean, and Italian. ONE CLOCK ON US Pick any clock as your gift and keep it free, forever: live in the app, on your widgets, and in StandBy. Every how-to-read guide is free for all 15. Want them all? A single one-time purchase of $1.99 unlocks every clock. No subscription, no recurring charges, no ads, and no tracking, ever. PRIVACY Strange Clocks doesn't collect your data. The one place it asks for location, to compute local sunrise and sunset for the Roman Hours clock, is used entirely on your device and never leaves it. Fifteen clocks. One phone. Zero reasons to know what time it "normally" is.
