Sorry to hear you don't like the app. The ad is necessary to support the free version of the app. You can collapse the ad with a single tap. You can also get the Pro version for a small one time fee to remove all ads forever. I wonder, what could improve? Why is the Pro version not an option for you? What is malicious about the app?
Thanks for your review. It's not possible for technical reasons to display the NTP time on the widget and there's an info pop-up that informs you of that when creating a widget. The only option I have would be to remove the widget altogether....
