How to set an alarm on iPhone or iPad?

Not any normal alarm. I saw on keek someone set an alarm on their iPad so when someone went on their iPad like a friend or something it would start blaring. This allowed her to catch whoever is sneaking on her iPad. How do I do that? Can I do it with my iphone. Whoever give me the most information and easy to follow steps will get a 5 star best answer rating

I know this isn't the best answer or anything but i'm pretty sure it is an app. Go to the app store and search alarm or something and it should come up. Hope this helps!

Hi
There are security apps when you activate them they act as burglar alarm for someone who touch the device. There are many apps available but I would like to recommend these apps
-Best Phone Security (free)
-Burglar Alarm (free)
-Secret Apps Lite (free)
-Lookout free backup (free)
-Finger Print security scanner (free)

All the above apps are great and quite useful.

  • Will i have to set up my alarm again? I'm installing the iOS 7 for iPhone and I'm planing on letting it install overnight. But i have to get up early tomorrow for school and the only thing that walks me up is my alarm on my phone. When iOS is installed into the device, do I have to set up my alarms again?
  • Trying to set up an alarm in the morning on my iphone without it draining my battery? So I want to set up my alarm clock in the morning when my phone is turned off but I know you can't do that so I was wondering what I can do so it won't drain my battery that's the only reason I want to turn off my phone off in the first place.
  • Clocks go forward at 1am (GMT), what happens if I set an alarm on my iPhone 4S? The clocks are going forward and I was wondering if my phone will pick up on my alarm being set at my time (7am) or if the phone won't change and it will only wake me up at 8am. Do I set my alarm TONIGHT for 6am (7am tomorrow) or just set it as 7am? Sorry if this was complicated
  • The alarm goes off at times I haven't set on my iPhone5 (last year's). WTF? I work shifts and I set it every week on a different shift pattern. I previously thought I set it to go off at the wrong time but it has definitely gone off at a time I didn't set. The time it went off, that alarm was in the off position with no days assigned to it at the time. It wasn't the shift I had last week either (it didn't get it mixed up/carry it over from last week). What can I do?
