Circa³ – Time Zone Converter

I found this when I was looking for a way to easily visualize what time it’ll be in another time zone at any particular time of day. That’s a task that’s surprisingly difficult with most world clocks. It’s proved useful for a bunch of times over the years I’ve had it. Most recently I used it to understand what my jet lag will be like for an upcoming trip.

If your right handed and move the needle, your hand covers the times the auto set your location is terrible picking places that are literally 3hrs away yet my mobile device knows my location for weather and mapping, so how can this get it so wrong? If I want a meeting with people in 5 countries I can’t add them in because the rings don’t get narrower to squeeze them in. Really really nice idea, but needs some user research and then a few iterations of design in practical user situations observing the tweaks necessary to make it a delight. This could be a winner if the work is put in.

Tired of standard international clock apps? Anyone can tell me what time it is NOW, but what time WILL it be there, when I’m available for that meeting here? And vice-verse. Clean, informative, graphic interface. Does exactly what I want. Drag the time hand and see what time it will be everywhere that you care about. Perfect for setting up international meetings. My only two quibbles: - A toggle between standard and military time. - An option to assign my own color choices. But, again, quibbles. Still gets the 5 star for functionality and execution. Worth the price of admission!

Great app. Clean design. Just two features/options would make this even better (1) be able use custom labels against the cities (i.e. team names and their respective cities/office hours) which would allow to layer multiple teams even within the same city and (2) customise the color. This would make this the perfect meeting facilator for global projects and teams.

Super handy and aesthetically beautiful app, very handy to have it on the watch. Would REALLY benefit from being available as a complication for watch faces. (Actually being a watch face would be great but I realize that can’t be done.) Absence of an available complication is the only reason I’m not giving five points. EDIT - I have to say even a temporary removal of the already somewhat crippled Watch functionality really impedes Circa’s usefulness. Very disappointing.
