Ratings and reviews

I love this app! It is the best NTP Clock app I have found. Ads are not obtrusive, but I paid for the Ad free version to give the author props. I only wish it had an option to display and update in tenths of a second, instead of showing ms ever 40 ms. Also, the offset from device time should be on it's own line at the bottom. All things considered, an excellent app, and not needing root to work is a bonus.

I installed the free version of the Atomic clock, but it appears the author doesn't want me to be able to use the free app, since the only way the widget comes out is white on a clear background, an unusable combination. In addition, the size of the digital clock's characters is too small. This app is crippled, so I deleted it. Good riddance.

Was a terrific app, but something seems to have gone awry with its widget. Was working fine until recent update. When creating a widget, it's quirky, for one. I no longer can get the weekday to show; selecting the option is now akin to selecting enter (and the weekday never shows like it once did -- for example, see the photos shown on this app page in the Play Store.) UPDATE -- Tried using the stock launcher, same result, ie, weekday no longer shows, widget is glitchy, doesn't display. Returned to preferred launcher, same result.
