Why did I buy pH test strips?

I mean, pH tests are handy in general, but I was reading a thread here and saw the kind that give you rainbow results, unlike the old pink ones. But for what? I don't remember at all. Cheesemaking, maybe? Pretzels? When would I need to test the acid/alkali level rather than just following the recipe? Any clues?
