Not worth $0.99

When I set the start time to 13:00 It wont let me set the end time to 02:00 saying ending time must be later than the start time Can you see this is stupid? What if I wake up at 17:00 and go to sleep at 06:00? I just wasted 0.99$ on a potentially-useful--but-not-yet app. Also I cant understand the the operating system lets you schedule only 64 alerts bit. Im sure theres a workaround. This app should be free. Its not worth 0.99$ imo.
