A sleep mode is what has been missing from the Symbian feature set for quite some while, or from the feature set of a number of operating systems actually. We’ve had a old Python app, but nothing like ‘MusicStopper’ that works out of the box and is a free install from the Ovi Store.
In addition to stopping the Music Player and Radio after the pre-defined period (1-60 minutes) the application can also quit other applications that you may have running.
Navigating the app is simple, all you do is slide your finger across the blue bar to change the number of minutes after which it will quit the selected task and then pick a radio button. If you choose ‘Other’ you will be presented with a list of options, pick one and hit hide.
Must have I’d say, free from the Ovi Store.
