Timing Animation on the iPhone

Here is something else to do with timing:
Disney animator Randy Cartwright has written an application for the iPhone called Animation Timer (AnimTimer); basically a stopwatch, you tap (or shake) the phone, and it will register the time between these (max. 20) events, and show this in frames (at 24, 30 or 50 fps), feet-frames or seconds. For sale at the iTunes store for $2.99.

The downloadable version must not be the latest, as the site shows the correct 25 fps for PAL video, and not 50 fps...
