It’s a very nice and easy-to-use counter. The ads are non-obtrusive, the controls are easy to understand.
The only reason for my 4 star review instead of a 5 star review is because for whatever reason, choosing a dark color for a counter does not turn the text for that counter to white. So if I wanted say, a dark gray counter, the text and numbers and all of that will still be black. It would be great if a color was dark to a certain degree, then the text would become white. The text is white on dark colors when you go to choose said color, but the counter itself keeps its black text.
Pretty annoying in my opinion, but not annoying enough to stop using CounterTallyCount .
Edit: The text in CounterTallyCount seems to be directly linked to wether the iPhone is set to dark mode or not. If the phone is in dark mode, then there is the possibility of having black text on a very dark colored counter (not ideal). If the iPhone is in light mode, then there is a possibility of having white text on a very bright colored counter (also not ideal).
