Following @bmikes suggestion I am listing the apps I have looked at so far. I must emphasize that none of them really solves the problem stated above perfectly.


Here's what I have looked at so far. **Note:** My first draft of this post included links to all the apps but AskDifferent won't let me post more than two links. [Find the same list in this Google Doc][1] with working links to all the apps. Sorry for the inconvenience.

 - On the Job looks great, but the developer seems to have abandoned it. At least he does not really fix bugs and is very slow to respond to his user base.
 - Timings light-weight but the UI to create clients, projects and tasks can be confusing. I am testing it right now. A friend uses it and says it crashes sometimes though it has not happended to me yet.
 - Harvest looks good, it does have a desktop client itself and an API that is used by lots of apps. But it is subscription-only which is a no-go for me and costs at least $12 per month.
 - The same goes for Toggl: looks good, but is subscription-based and consts $5 per month
 - iBiz and timeEdition have been discontinued
 - Klok is an Adobe Air app. The UI feels weird. Small typography, limited support for keyboard shortcuts and complex interface.
 - OfficeTime feels like the best match so far but the UI is very cluttered (see this screenshot of the Generate Bill dialog as an example). It feels a bit like a Windows app that has been ported to Mac but I am not sure if that's true.

All I want is a pay-once, stand-alone, well-supported and nicely designed time-tracking app. Am I too demanding? Or missing a good product?
