Excellent. It has no complications. Simple for my purpose: set an alarm for a specific day. the other calendar kind of default apps only give notifications. for me, some special items should not be missed. surely they are are very less and it been scheduled here. Anyway I am not using all the options. I am depending on google calender for my generic appointments. also using android alarm app (MIUI) for normal alarms. I like the user interface. it is simple with elegant big icons. as davinci correctly said simplicity is the ultimate sophistication. Kudos to the development team. still you are giving this for free. Thank you. I am logging this review after 1 hour of installation. will revise if I find any issues..
