Schengen Calculator

U.S. passport holders are allowed to visit countries in the Schengen area (which comprises most of Europe) for up to 90 days in a 180 day period. That can become tricky to calculate for digital nomads and other frequent travelers, but a free iPhone app called the Schengen Calculator makes it easy to see how many days you have remaining. Schengen Calculator Free is a similar app for Android. — MF
