If you have the foresight to download this app AND the city maps ahead of time, then you will be impressed. It works perfectly when in airplane mode, and has saved my butt countless times when Im in a foreign city with no connection on my phone. A quick tip: search for key destinations you know you will be visiting and drop pins there before you visit - it can be a great backup plan in case you get stuck somewhere. Also, always download additional content when downloading maps - it helps give more searchable info when offline :-)
