Have you at all checked if graphic designers need this sort of functionality? I tinker with pixel perfect designs quite extensively and zooming in is the way to get more precision out of mouse. Few designers on Dribbble posted videos showing how they work and this use pattern - zoom-in, tweak, zoom-out - is so engraved into their work style that I am having hard time imagining why they would switch. Also, consider the fact that even if the mouse is moving slower, the pixels are not getting bigger. In other words, increasing mouse precision does not remove the need for zooming in. Especially on larger screens.
So there you have it :) Great app, very well done website, but I think ultimately the niche is not just small, it is also very oddly shaped.
(edit) Perhaps repackaging the app and re-aiming it at gamers (as others suggested) would be a thing to try. Though on the other hand many gaming mice come with a hardware button toggling the deceleration.
