Every minute, piClock scans through ribbons of digits from the number pi to find the current time and date.

26,289 digits into pi lies the block “1234.

See how many places past the decimal point a four-digit block such as “12:34” lies, and where all the other occurrences of that block appear amid the first million decimal places.

piClock Constants Not in the mood for pi? Try a different (à la) mode.

Scientific types may take a natural interest in Euler's Number, e, while artists and architects might have a proportionate affinity for the Golden Ratio, phi. Or even double your pi-leasure and take a turn with tau.

No matter in which of these you irrationally place value, piClock covers the bases.

* Subject to availability (currently limited to four choices).

Universal Constants
As a single app designed to run on both iPad and iPhone (with graphics optimized for the Retina Display), piClock can not only put times on your table but also function as your constant companion while you’re commuting, associating, or even distributing.

C’mon Get (Digit-)Happy!

If it weren’t for the decimal point,
this game would have no point at all.
piClock for iPad includes DigiTappy, the ultimate test of press-the-digit-ation.

Simply tap through each digit of pi by touching the screen with “that many” fingers.

How far —and how fast— can you go?

Master Time and Pace
Assign time and date numbers separately, and choose which display formats you prefer.

Don’t care to wait a full minute for action? Shake piClock to get things moving at will, advancing instantly from one occurrence of “12:34” to the next, until “12:35” arrives.

And if advancing one-by-one through the occurrences of a four-digit block lacks excitement, perhaps the “Random Locations” setting will provide the chaotic thrill you desire.
