How do I set my alarm on my iPhone to vibrate?

Help on Iphone alarm clock?!?

• So..my mom wants me to have an alarm clock for this eating pattern: 7, 9:30, 12:00...etc. But im scared that it will go off in class because if when i put the phone on silent or vibrate the alarm is still very loud with sound! Can anyone help me keep the alarm but with out the sound, it would be good to if there was no sound for the ones i pick...but still letting it vibrate?

• Answer:

  The first thing that comes to mind is to use a calendar app like Sai Suke or CalenGoo, and sign up for a Google calendar. Then, thru Sai Suke or Calengoo (I think they both have free versions) you can set these up as repeating appointments with an SMS text reminder. When you get the SMS text with your phone on silent, you'll get a single buzz instead of an alarm. The problem with most alarm clock apps is that they have to actually be open to work, and it's hard to customize the alarms. I don't have my phone with me right now to fool with, but if I think of something else I'll let you know. I use the SMS alert from CalenGoo more than I use the iPhone alarm clock, honestly.
