I've had this idea for many years. Most clothes washers and dryers have some sort of audible signal to notify you when they are done, but if you are too far away or there is too much other noise in the environment, you might not hear it. It would be useful to have an alternate method of notification. It could be something as simple as a radio signal to a receiver device that you clip on your belt, or something more complex like interfacing with a smartphone or tablet through an app. It should tell you whether it was the washer or dryer that finished, maybe allow for a reminder notification if you don't respond and maybe even have a timer that starts counting when the notification is received to tell you how ling it has been that your clothes have been sitting there.
