Wow. This is clean, functional, literally ticks all the right boxes.

If I could give any feedback at all... My muscle memory instinctively looks for a settings cog in a corner. I'd suggest rotating the position of the Theme, Settings & About buttons clockwise (https://i.imgur.com/OtTO2uG.png) or at least, swapping the Settings & About buttons (https://i.imgur.com/bCymnqr.png).

But that's a small nitpick, I'm being extremely pedantic. Honestly, I'm genuinely impressed by the thoughtful details you've included: the option to disable the reset confirmation, revert the interesting bubble-like layout, and change the increment value. These are exactly the kinds of features that I'd imagine are often overlooked.

If you ever plan on expanding it, support for multiple tallies would be a killer feature. But honestly, it's already a perfect little app. I'm keeping this one in my back pocket for when the need arises.

It's quite snappy and a nice UI, pretty much needs to look good on phones too though

The world's most boring clicker game!

Seriously though, it's very effective and looks great.
