Scott Hanselman has done a review of OnTime on his web site:

A few of my favorite quotes...

“There is an SDK in the form of a rich Web Services interface...This is pretty powerful stuff and it's a shame more applications don't take the effort to expose their core engine as Web Services.”

“The [OnTime] WinForms and the [OnTime] WebForms applications have surprising parity of look and functionality...The WinForms has a nice, speedy UI...I was able to add a custom field to my bugs (I added "locale") and associate a pick-list with choices (en-us, es-mx, etc) without trouble.”

“All in all, OnTime 2005 Small Team Edition offers a great deal of value for the $ in my opinion.”
