For those of you familar with the Treo you probably rememeber the very useful application "Butler."
One of the nice features of Butler was the "nag" option where the device would sound an audio alert for missed calls and continue to do so until the until was touched. This is especially useful for devices where the screen turns off completely making it hard to know if a missed call notification is sitting on the screen (unless you use the LED) or turn on the screen every so often to check.
Well today I stumbled across "Missed Call Notifier." It looks like it's new, maybe I just haven't seen it before.
Anyone using this application? I'll give it a whirl today but wanted to hear some feedback from others as well.
