IPhone :: Timer App That Will Log Into ICal?

There are a million timer aps, and project management apps, and other variations on time logs. But I have been unable to find one that does precisely what I want to do. Start a timer on my iPhone when I begin work on a discrete project. Stop the timer when I stop work.Have an iCal entry created on my iPhone calendar which indicates that block of time. I do NOT need to manage a large number of projects, create complex reports, do billing, or anything like that. I am just looking for a way to be able to open iCal and get a visual assessment of when and how much time I am actually devoting to three-five priority areas.

Here is what I have been able to find and do NOT want:Manually creating iCal entries with start and stop times, that the app can then aggregate and report time spent.A timer that creates a separate log or standalone calendar - completely removed from iCal.

If I start working on a goal area at 3:15pm and stop 90 minutes later, I want to be able to start the timer. Stop the timer. And have an iCal entry that starts at 3:15pm and ends at 4:45pm automatically created in iCal.

Info: iPhone 4, iOS 5.0.1
