With COVID-19, my graduate program transferred online. With that, I went home... I also went to a different time zone. This has been a fantastic help making sure I am submitting things on-time and attending meetings on-time since all due dates, exams, etc. are based on central time. All it takes is a quick glance at my menu-bar and I know what time it is - no more second guessing myself, and no more having to bring up the clock app on my iPhone to see the time - I can do my work and know what the time is without interruption! Exactly what I was looking for!

Very useful

In this COVIDious time I'm attending various Dhamma talks and meditation sessions via Zoom; some of these are hosted and/or posted in Singapore, Australia, and various other parts of the world. Clocker helps me to figure out at what times those things are happening in my time zone. Invaluable, and much handier than having to go to websites to figure out the time conversions (though such websites can still be plenty handy for greater detail, including determining the time offset from UTC, since some people will say an event is happening at, say, 8 AM Singapore time and others will say it's happening at 0800 UTC 8). Which made me think of a feature request for Clocker...and as it happens there's a very handy feedback form built right into the About section of Clocker's preferences.

Love the compact menubar display that lets me see a couple (or a bunch!) of my chosen clocks at a glance.

Odd things:

1) The list of my chosen clocks in the preferences is in huge type, much bigger than any of the other UI elements. Not sure why that is.

2) The menu often needs to be clicked several times before it'll open.

But those minor things aside, it's a pretty slick app and, as I say, very useful. And it's free, no less! Wowza. =)

Very Useful

Having family members all over the world, I have found Clocker to be extremely useful to keep track of when they are awake and asleep. They've been adding new capabilities that I haven't yet taken advantage of, but simply having a list of times and dates with a simple visual of it being daytime or nighttime has been a great addition to my menu bar. I imagine the additions are helpful to some, I hope that it doesn't become bloated with unnecessary things. I enjoyed its simplicty when I first started using it. I just updated to the newest version and see that clock faces are no longer the default view. I hope there's a way to choose that view still.
