change ringer to silent apps

[aaranan]

Hey guys,

I need a free app that changes the ringer/profile on my phone to silent at schedualed times, then changes it back to the normal ringer;

for example I want it to change per day to match my school schedule so i want an app that sets that all up

I currently use SILENT TIME LITE
BUT it dosent put the phone back to the ringer for some reason:anyone know why this is??

thanks !
