Trouble waking up!

Emma
I'm having a lot of trouble waking up in the mornings. I have some hearing loss but I'm not sure to what degree it is. I like to work out in the mornings better than at night because I find it hard to end my day when I want to because of the endorphins after I work out, and I work pretty late usually so it's hard for me to go work out after I work. 
Does anyone have any good Apps for alarm clocks? I have an iPhone and usually it takes a few alarms to wake me up. I'm also in college so I don't want to wake my roommates up in my apartment.
