Freckle is a popular time-tracking application conceived and developed by Polcode and a very well-known team: Amy Hoy and Thomas Fuchs – important RoR world personalities. It boasts many additional features and a generally more flexible approach to time tracking, taking into account
all activities, not necessarily fully related to billed work. It could be described best by saying that it is developed by programmers for programmers, except that it is not only programmers that can profit greatly from using it.
