AtomicClock: The most accurate time on Android.

Ratings and reviews

a very nice app to have. I like having one accurate source for the correct time that is as handy as this one and as easy to navigate. Visually, it is very clean with many options for displaying the time both digital and analog. Another bonus is that it is very small and has never given any me any problems. Good job, developers.

DACri here: I love the colors to choose from and I wish it had a display widget for my home screen where the clock face can be seen on screen without me having to open the app. Not really sure why I actually need this, as my phone is automatically updated with current time and date even when I cross time zones. Anyway, I like the app. I guess, because it says ATOMIC! I would like the app much better if you had artworks similar to Salvador Dali' painting "Persistence of Time."

I opened the screen on my app and found it running quickly, date, hour minute and second just doing its job. I love the dark back drop for easy reading, especially when I have just woke up and also because my photophobia can be upset by a too- bright screen. (That's a thoughtfulness other apps could learn from you.). I would like to add that while some folks can only read digital time, you offer a face clock as well. If you offered a calendar/alarm clock I could get rid of 2 other apps.
