Why do you think iPhones only allow one timer? I've been using an app that has multiple timers for years on an iPhone 6s. If you're talking about the stock Clock app then you're probably right, they just didn't feel like adding a little more complexity to a stock app.

My friend argues those are potentially less accurate than Apples single timer, if Apple is doing some special hardware interfacing versus what a 3rd party app would use with public (polling?) APIs

I doubt it about the accuracy but I could be wrong. It's in Apple's best interest to push people to use App Store applications so that might have something to do with it.
