An alarm clock application for a device having a touch screen, in which time entry consists of progressively entering data into each of three singularly functional groups of keys, comprises: a) a 4 digit time display portion; and, b) a keypad portion consisting of three separated, functional groups of keys: i) a first functional group of keys which provides only a choice between a clock time set function key and an alarm time set function key; ii) a second functional group of keys for time entry, which provides only a ten numeric key group numbered 0-9 for entering numbers; and, iii) a third group of keys which provides only a choice of AM-PM function keys, to finalize any time setting sequence. After time entry consisting of progressively using each of the three singularly functional groups of keys, all entries can, at any time, be reviewed with a glance.
