What's a good iOS app for planning my route to the clinic while dodging bad weather, especially when I'm already running late for my shift?

Okay, so, I'm too tired to learn complicated apps, but Weather on the Way is seriously a lifesaver. It's like having a pocket reference guide for meteorology, but way easier to understand. What I love is that I can plug in my destination – say, the clinic in Evanston – and it shows me the weather *along* the entire route, not just at the start and end. This has saved me from driving straight into a flash flood more than once, especially with Chicago's crazy weather patterns. Plus, it hasn's crashed once in the six months I've been using it, which is saying something. It’s actually reliable, which is a MUST during 12-hour shifts when you're already running on fumes. No-fuss approach, which is exactly what I need.
