Just for giggles decided to act like someone who got the app and is going to look for the map for the first time.
While it's great you can get to the map in one tap here's what you see first and then when you zoom in:
You know who has a slightly better experience compared to this? Freakin' SeaWorld!
At least you can easily name where you're at right away. I'll also say it's more pleasant to look at over the orange icons at first glance but that's a personal design critique.
In Universal's app you have to do all sorts of extra tap dancing to navigate where in SW's it feels like there's fewer steps needed. The Directions feature in their (SW's) app is also very handy—I used it a few times on my recent trip.
One thing physical maps have going for it is the space to list more information at an overall glance than the apps can cover without becoming cluttered or doesn't result in a lot of extra tapping and scrolling. If Universal is going to completely do away with traditional maps (or at the very least make them less easily accessible) then the virtual experience needs some polishing. And still have paper maps available.
I'll say this for any park: An app should optionally enchance the vacation experience, not require its usage.
