JAC (Just A Clock) — for when you just need to know the time.

One or more resizable traditional (analog) clocks showing the time in different locations.

• A selection of functional designs, primarily minimalist but including some seasonal fun.

• Optional date, timezone and AM/PM display.

• Uses system language & calendar for display.

• Clocks may optionally float above other apps, or be brought forward using a hot corner.

• Spaces/Mission Control aware.

What's New in Version 3.2.1

Fix for intermittent display issue when JAC is opened at login and a clock overlaps the Dock.

Exactly what I was looking for!

I have frequent overseas business trips and time can be very confusing when you are working day/night. I can always find out what time it is where you are or back home but I needed something that stay more visible and easily accessible. Clock stay visible or via simple hidden corner. When I write an email, schedule a call or reply email with time in mind, this keeps me straight on what the time means to me or the other party so that I don’t accidentlly put something too early/late. And also keeps things clear so that I don’t miss anything due to confusion. Only one ask is if you can also provide a resizable digital version so that it is even more visible among all my open windows!

Setup is not intuitivebut once setup works well.

Lets you name the clocks
Drops from the bar
Can be system so no open app on Doc Bar
Some visual styles to choose from.
Interface can be confusing when trying to name the clocks but stick with it.
Map view for loacting time zones is cumbersome to move around in.
Names of places appear in clock name in a way that overwrites my typing and had to renenter a clock several times.
No way to modify a clock name, have to delte it and start over.

Excellent app!

Make clocks for cities around the world you want to keep in touch with. Works very well. Be nice to have bolder , more readable type on basic fully numbered analog clock. Otherwise perfect.
