    NS Reisplanner Xtra
Need to get to the city? NS is the main train company in the Netherlands. Their useful planner is a good app to have when you use public transport in the Netherlands.
One of the organization team members is a big fan on this app. Foursquare is a location based app which gives you recommendations for coffee places, restaurants and other places of interest in your area. 
    Google Maps
Google Maps has a very good coverage regarding public transport in Amsterdam. Use this to plan your travel by public transport.
Be aware of the prices of regular taxis in Amsterdam: these are fairly high. Uber offers a good alternative and the coverage is wide. The standard fee from Schiphol to Amsterdam is €28. Never take a taxi offered to you in the terminal or on the square in front of the terminal as these will charge you too high fees.
    Field Trip
This app uses your location to determine if there is anything interesting around. Recommended for Amsterdam. 
    Street Museum NL
This app enables you to see how buildings looked like in the past, by just pointing your camera towards it. Since Amsterdam is a city with a very rich history this is an interesting thing to do.
