It is called FastMall and is FREE in the App Store
This app will :
- Locate Malls close by
- download the layout of the mall for you so you can see where any store is
- shake the app to find closest restrooms
- locate ATMs within the mall
- Allow you to save your favorite stores on a list
- Show you which stores are in the mall you are looking at
- Locate Escalators, Stairs , Food Courts and Theatres
- Allow you to search by category like "show me stores in this mall that sell tennis shoes"
Overall the app is brilliant, but a little buggy. Can't complain since it is Free. Oh and I forgot to mention that there is a deals tab you can click on to view sales happening in whatever mall you are navigating.
