6) Motion Alarm Clock

Quite a simple one here: All that Motion Alarm Clock asks for before shutting the alarm sound off is a bit of motion. It’s one of the most straightforward and also one of the most effective ways of waking up, and it’s also one of the oldest alarm clock apps out there.
Its longevity is testament to how many people it’s helped get themselves out of bed when needed, and if nothing else has been working for you, the developer promises that this is “impossible to sleep through”. An in-app purchase is available to remove the advertising.
