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.

You can absolutely configure what time zone is shown in the widget. You can set it up while creating the widget. Can you write me a mail with more details on this problem?

Only improvement would be to add an option that prevents the "jumping" when using 3 decimal places due to certain font settings. Other than that, thanks for building a useful app!

The new type of ads that covers half of the screen is absolutely unbearable. Yes, you can fold them but this is soo much, really. Uninstalled.

Sorry if the ads are too annoying for you, I don't like ads either. Unfortunately, they’re the only way to offer a free version of the app. I’m a solo app developer and rely on the income from my apps. You can always purchase the Pro version for a small one-time fee, and all ads will be gone forever. Why is that not an option for you?
