As a fun little programming and graphics exercise, and because I wasn't completely satisfied with any of the existing predictors (plus because I generally like to do things myself
), I made my own Pod Clock that graphically displays the time of day in all four pods in relation to surface time and predicts portal appearances. It has now matured to the point where I'm comfortable with sharing it, so, with permission from Cyan, here it is! Hope some will find it useful.
Some of its notable features:
A screenshot for the impatient:
It is written using wxPython and works out of the box on Mac OS X 10.4 and 10.5. For Windows, a self-contained installer is available, and on other platforms, it runs as long as Python >= 2.3 and wxPython >= 2.5.3 are available.
Download version 1.4 as
Since 2009, a version for iPhone and iPod touch exists as well – it is discussed in this thread.
1.4.1, 2010-04-12
1.4, 2010-03-28
1.3.1, 2008-04-04
1.3, 2008-03-09
1.2.1, 2007-11-01
1.2, 2007-10-01
1.1, 2007-08-19
1.0.1, 2007-08-01
By the way, despite a certain similarity, this is completely independent of the web-based graphical pod calendar by Mucol and Modi. I wasn't aware of the latter at the time I started this. It is also completely independent of the recently released portal predictor by Herohtar. See here for a list of other pod calendars and portal predictors.
Some of its notable features:
- cross-platform offline application
- need not rely on built-in data to predict portals (although it can), but you can calibrate it yourself using your own observations (in uncalibrated state, predictions may be off by several minutes, calibration will make it more accurate)
- displays local time, UTC, and KI time
- can alert you a specified time in advance of a portal
- drag the time scale to any date in the future or past

- a Mac OS X application
- a Windows installer that includes all required libraries, by Darrigan
- a simple Python script for all platforms (Python and wxPython must be installed separately)

1.4.1, 2010-04-12
- Mac: Fixed failure to launch on Mac OS X 10.6.
1.4, 2010-03-28
- Updated built-in estimates for MO:ULagain. The predictions may still be off by a few minutes though – this is deliberate! Do your own calibration or share calibration points with other explorers to make it more accurate!
- Better combination of observations and built-in estimates when there are not enough observations to base everything on them. Adding the first observation will now shift all predictions, not just those for the observed pod.
- Calibration files with fractional seconds, as produced by the iPhone version, can now be loaded.
1.3.1, 2008-04-04
- Fixed the KI time scale showing a wrong date when the left edge of the scale was between 0 and 7 UTC.
- Adjusted the KI time scale assuming that it will switch to daylight saving time on Sun April 6, in accordance with the US DST rules from before 2005.
- Updated built-in estimates from recent data.
1.3, 2008-03-09
- Improved numerical precision, particularly for the error estimates.
- Updated the built-in estimates from recent data and removed the artificial error that was introduced to encourage people to do their own calibration. Predictions should be accurate to a few seconds right now.
- Adjusted the KI time scale to never again switch to DST, since it hasn't switched today. We'll see in 3 weeks whether another update will be necessary.
1.2.1, 2007-11-01
- Adjusted the KI time scale which has reverted to standard time a week earlier than expected.
1.2, 2007-10-01
- DST transitions should now display correctly on the time scale (for regions where they happen on a full hour)
- KI time now correctly follows US/Mountain DST rules, not local ones
- added 12 hour clock option
1.1, 2007-08-19
- added estimation of prediction accuracy
1.0.1, 2007-08-01
- fixed predictions not updating on calibration changes when no pod had more than one calibration point
- added clarification to calibration window
- source distribution now includes Windows icon
