One Of The Best

GUI ****
Easy and intuitive. Needs additional information on how the night mode functions.

Display *****
The display is the best, using the most readable fonts and clock faces. Offers both analog and digital clock faces. The colors, hands and design of the clocks can be changed by the user.

Alarms ****
The alarms perform consistently, but the choices are limited and the volume on some is too low to be effective for sound sleepers.

Snooze *
Multiple users note that the snooze function disappears inexplicably, in my case on a 128GB iPad Air iOS 9.2.
