Ratings and reviews

Worked fine for a while, but in recent years hasn't. No matter how many time I chose UTC in the settings, it will always display local time in the widget. If I want to see the time I selected, I have to open the full app. No time won there, pun not intended. Keeps time perfectly fine, much better than what the cell network does. Doesn't seem to be supported anymore; which is a pain, given I paid for a license.

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.

I installed and tested more than 2doz clock apps to find the best one. This one is head and shoulders above the rest. I love everything about it. The numbers on the digital clock are large and easy to read. Love being able to customize the analog clock with different faces/numbers (or no numbers) and hand styles, fluid or ticking seconds hand and different clock colors to make it easier to read. Ads are not intrusive. Worst thing is not having enough characters to say all of the things I love...
