Does not sync to the nearest atomic clock merely to public NTP servers, some not even stratum1. Would be nice to choose the NTP server

This is a great application.

Be sure to go to the awyse website for set up instructions

The next time you are in a meeting with architects, engineers, and the Building Official, and someone asks "what time is it", whip this out! Don't forget to appologise for only being accurate within 1/100 of a second. Everone will laugh and say "that's not good enough" as they stare in amazement. I also use this to set all the other clocks around the house. It's is beautifull and the most accurate. Can't afford it? Just skip your Starbucks coffee for one day! If you want a good clock, it's worth it.

I went to the website and I read the info..

Right on the money. Exact same time as listening to NIST time via shortwave. Would be nice to let it sync the built-in iPhone clocks, and a choice of NTP server would also help.

Not only is this a very useful tool for accuracy geeks, but it's great looking too. Both the analog and digital versions are very compelling graphically. An excellent app!

It's accurate and it does not cost $200.00! It's my favorite app!

I often want to set my analog watch but aren't near an atomic clock but now I always have one with me. The utility does what it says and works perfectly.

When I first installed it worked fine and I was impressed. The following morning it suddenly doesn't want to connect to the server and remains offline. When I manually press refresh it attempts to query server then remains offline. It does admittedly connect at various times of the day I found but it's anybodies guess for it to be successful.

This app needs to sync the iPhone's clock to atomic time when it launches. Mine shows an offset of almost 2 seconds, yet the iphone's own settings are set to get the time from the US time server. Obviously it doesn't do that all that often and there's no way to force a sync that I could find. This app should do it.

The last version I purchased of this said future updates were included also... Yet I haven't received one but there is a new version out....hmmmm...

Very beautifully designed, but the app does not adjust the iPhone's system time, which was what I needed done when I purchased the app.

This is a great app it's very accurate I checked with 3 other atomic clock nist,usno,timeanddate

I didn't read the instructions and had problems, then following a post I found and read the instructions. It is really a great time keeper, in either mode.

I love the interface, very slick. I'd give 4 stars even without the atomic feature. I have a couple suggestions:

I bought this App less than a week ago for $4.99. I just saw it the App Store for $1.99 WHAT"S UP. Plus it just shuts down whenever

Well designed. It would be nice to have a 12/24 option in the digital skin. And sometimes I wish I had the option of turning that little flying ball off, but I can live with it.

Excellent App!

The set up process was pretty painless...

Since we have summer time in USA it is missing this capability. It would be an easier implementation. Also how to sync the iPod time? Automatically? not clear.

Very Accurate! Does what it says. I wish it did not crash as often as it has, may be an OS 3 comparability issue. I'm going to use this to set the clocks in my home!

I wish the next update. If there's one. Please add a date. Don't have to include month or year. If you can it'll be cool. Thanks.

Works as advertised, but needs additional display options like choice of 12/24 mode and date display. Would like to see a generic digital hours-minutes-seconds display option without the glitzy animation... How many people care about centiseconds?
