In a new blog post, TapSense on Thursday clarified that plans to integrate ads onto Apple Watch watchfaces might not even work at all. TapSense also made clear that the company wouldn't be able to integrate ads in Apple Pay either.
Ultimately, Apple has the final word for what appears on their products and an ad filled experience isn't something user desire at all. Blogosphere speculation claims that TapSense might have announce the new ad service just to get some press and attention.
