I listen to music/noise on my iPhone to help me fall asleep, and therefore have to set this alarm to also go through my headphones. If I set it to internal speaker (so I can actually hear it!), then it makes every other app ignore my headphones as well! (and my husband does NOT want to hear waves and stuff all night). If the headphones manage to stay in my ears until morning, its great. Alas, they usually dont, and I just wake up to a lot of unheard, angry CARROT alerts.
