My clock application/program is now updated with alarm clock feature. ClockZ v3.1 Public Key: P5VXVVKE

Here's the lower screen looks like. Note: Alarm feature will not work when the 3DS is on sleep mode.

can I ask a question? How did you replace the number text with your number sprites for the analog clock? '_'

@CatDan, for analog clock, I set the following sprites 11,12,13 for hour, minute, second respectively. For digital, I set two sprites for every digits of hour, minute and second. Sprites 1 & 2 for hour, 3 & 4 for minute and 6 & 7 for seconds.

Here's another screenshot of the lower screen.

An update of my ClockZ v.3.3 now with calendar.
