Beautiful, but with difficulties
A very unique and beautifully working app, but setting the time exactly to, say 3:00PM is very difficult. I can suggest a modification. There is a specific amount of length you have to pull from the tray icon to change the number of ‘x minutes by ‘1’. It seems to be about 1mm according to my Macbook Air screen. You may want to increase the amount of length of the pull for some specific x, for example 15minutes, 30minutes, 1 hour, etc so that it is easier to set the time for minutes that are often used. Also, you can increase it for a value of x that makes the moment of alert y:00 AM/PM.
