During my time in Okinawa, I've relied on my iPhone to be my navigator, researcher, and travel companion. My husband holds all of those titles, too, so you can see that my apps are pretty important! Below you'll find a list of 10 apps that I think you'll need during your time in Okinawa.
This app is also great when traveling to other countries while you're here. Currency conversions can be super tricky!
Skype subscription, which I highly recommend. Otherwise, if a Skype user is logged on you can video and/or voice chat.
