Coming to Israel with a smartphone? Even before you arrive you will want to install some apps that will make your trip more pleasant. igoogledisrael has compiled a list of 10 apps all tourists in Israel should have, including Trip Advisor, Instagram, Waze and Old City Walking Tours. Trip Advisor provides user reviews for hotels and restaurants. Instagram is one of the easiest ways to share photos you take in real time. Waze will get you anywhere you want to go if you are driving, and Old City Walking Tours will guide you through the Old City of Jerusalem on foot.
