Volume schedulers

[Claraviolet]

For people who work in an office and who don't want to draw too much attention by using the maximum volume for a ringtone, try volume scheduler. You could specify at what time, how much ringing volume should be used.
It's really helpful and I use it.

You should also mention that if they restart their phone then they should open the application at least once for it to work. Otherwise people might get confused

Yikes... Yeah.. But sometimes it works and most of the time it doesn't after the restart.
Anyway opening the application would usually do the trick in such times
