## Sky Time Reviews in United States

### ***-- "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
-- HarveySLiszt, 2025-06-17

### ***** "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.
-- Skald Cat, 2024-01-20

### ****- "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.
-- jec249, 2020-08-12

### ***-- "Not available as Complication"
Would be nice.  No?
-- NoBaseLikeHome, 2020-05-04

### ****- "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.
-- Jim the astrophysicist, 2019-11-18

### ***-- "Text to small in field"
Exactly the app I was looking for: something to be a field clock while doing astronomy.

Except that everything but the local civil time is too small to easily read at night, and so I don’t use it.
-- PaplooTheLearned, 2019-06-30

### ***** "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.
-- iownacamera, 2019-01-20

### ***-- "Parts not working"
I think the actual information displayed is correct, but...

- It won't display in landscape mode on an iPad, so I can't leave it propped up on a table and read it properly.
- The help menus don't work--I can't get the explanations of the different times that are shown in the examples in the AppStore.
-- pocketthinker, 2018-06-24

### ****- "Great for astronomers"
Nice simple app that allows me to setup my telescope computer.  The red theme is perfect for this, no need to change. 

Would be nice if updated to use all of the iPhone X screen.
-- NakMan, 2017-12-25

### ***-- "Color Makes it Hard to Read"
Needs a new color scheme. Red on reddish background doesn't make it. Check out a newspaper, magazine, or book, all designed for maximum ease in reading, maximum contrast. Black type on a white background.
-- Daoud, 2017-09-03
