I loved this but it doesn’t work any more on new gear

The app can’t determine current location under iPad OS 18.5

Awesome app

Awesome app. About the only thing they can do better is add in watch complication options for each unit of time. I’m personally dying to find a watch complication for MJD from anyone. Really!

Great work. Love your app. Hope to love it better.

Does not work if you’re in half hour time zone

Review title says it all. I’m in a half hour time zone so the app miscalculated UTC as it doesn’t account for this.

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.
