The built-in Apple Maps app is just lacking and annoying to use, don’t you think? Well, there’s an app I’ve been using called Waze and, so far, I’m impressed with how accurate it calculates and recalculates the ETA to your destination. On top of that, it’s smart enough to change it’s route based on traffic. I’ve been using it daily – just even to know how long it will take me to arrive at my destination. That says a lot.
