Nice, but...

I like almost everything about this app except for one little thing that just bugs me. The sidereal time is displayed down to the second, but is only accurate to the minute. For some reason the developer chose to display the same value for seconds on sidereal time as for local and universal time. That’s just not right.

Great clock. Great astronomy app (with suggestion to developer)

If you are an observer this one is for you. Don’t need to say anything else. Case closed.
As I said one suggestion to developer... Can you make option to display sidereal time as the primary clock? That would be awesome. Right now it’s just as one of the secondaries. That clock I think is the main reason why someone would get this app, so make this a primary clock, please. Or include as an option, please. Thank you very much.

Great idea! BTW, I've put the source code for this app on GitHub so if you are a developer you can do this yourself. But I'll make it happen in the next update. Thanks again!

Nice app, but problem with sidereal time.

I use this in a lab course on radio astronomy I teach to quickly see what the local sidereal time is.
This is the problem: When the seconds roll over from 60 to 0, the minutes do not increment by 1 until after 20 seconds have passed by. This is on an iPhone 11 pro.
