For web, front-end, or mobile apps (excluding games), I agree math is not necessary. These type of apps rarely uses math, they simply streamline data and present it on the screen. It can't hurt, but it isn't a criteria when I interview developer.
Of course, once you get into back-end systems, data analytics, and algorithms, math becomes much more useful, if not a necessity.
