Where would I be without WhatsApp? This app lets me keep in contact with everyone back home and with my friends here in Germany. WhatsApp is a free messaging app, just like iMessage, that doesn’t cut into your monthly text allowance. It’s an app that allows its users to text, send media and voice recordings all while syncing with your contacts that are already logged in your phone’s database to make communication easier. WhatsApp uses the same data that you surf the web and send e-mails with, so there is no fee to keep in touch with friends and family back home or down the street.
