I have a Motorola Droid and I was wondering if anybody is aware of an app which will allow me to disable the email notification sounds and text message sounds while I'm sleeping but KEEP the ringer? I get a lot of email from subscriptions in the middle of the night. I found an app called Timeriffic but it disables the ringer along with the notifcation sounds... I'm looking for a free alternative and something which will be more convenient than manually changing these options when I go to sleep and wake up!!
