Hi, I wrote the app. If someone had an Apple App Store account and was feeling enthusiastic it should be easily portable to iOS, with some minimal changes (because it's done in Phonegap). I don't have an iPhone however so I would be a little concerned about getting it to look right!
UPDATE: The arbitrarily named Version 0.9 is out! Improved look, removed a weird bug when you pressed the menu key, and time is now presented in minutes and seconds (instead of "295 seconds").
