Many people use the alarm feature in their iPhone’s Clock app to wake up on time for school or work every morning, but sometimes users will hit the stop button and inadvertently fall back asleep, defeating the purpose of setting the alarm in the first place.
You could create a cascade of alarms to prevent this from being a problem, or you could use a new free jailbreak tweak called AlarmGroups by iOS developer Fouad Raheb, which streamlines the process of generating and grouping multiple alarms to ensure you wake up every morning.
