On OS X and iOS there are two different kinds of progress bars. Normal progress bars and indeterminate progress bars. Normal progress bars are used when you know the actual progress. Indeterminate progress bars are used when you don't know the actual progress and you don't know how long it will take.
Here is a video showing an indeterminate progress bar:

- lloeki 13y agoThis is similar to bootstrap's .active.progress-striped progress bars[0]. We use bootstrap already, but I wanted the user to feel a sense of progress, whereas the indeterminate ones merely give a sense of action. The iOS Messages app has a SMS progress bar that is totally fake: its duration is actually the mean duration of the last time it took to send SMSes, and is made to fill up to ~80% in that duration. It takes advantage of the knowledge that the exact same task takes about the same time. So despite being fake, its progress statistically makes sense and gives valuable, quantitative feedback to the user.
