Entorii - Schengen Calculator Track the 90/180 Day Rule

Travelers navigating the Schengen Area's 90/180 day rule can track their compliance with precision using Entorii, a cross-platform application designed to eliminate the guesswork from calculating permitted stay durations. The tool addresses the rolling 180-day window requirement that limits non-EU nationals to 90 days across all 29 Schengen member states—including Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and Switzerland. The dashboard provides an at-a-glance view of compliance status, displaying days used, days remaining, and a visual timeline of recorded trips. Entorii employs a precise rolling 180-day window calculation that counts every day spent in the Schengen zone within the last 180 days from any reference date, then displays how many of the 90 allowed days remain available. Beyond basic tracking, the trip simulator enables users to plan future European travel by modeling how proposed trips will impact remaining days before booking. Smart alerts notify users when approaching the 90-day limit, while passport reminders provide automatic warnings at six months, three months, one month, and one week before expiration. A standout feature is the PDF report generator, which produces a professional document containing complete travel history, days used and remaining, calendar overviews, and rolling 180-day window calculations. Users can present this report at border control to demonstrate compliance, offering a clear alternative to manual paper calculations. The PDF includes the traveler's name, trip history with dates and countries, and a summary of Schengen stay calculations that can be shared or printed before departure. Entorii is available on iPhone, iPad, Mac, and Android. Apple device users benefit from iCloud synchronization across devices and a home screen widget that displays remaining Schengen days without opening the application. The app has received a 4.1 out of 5 rating from 35 reviews on the App Store, with users praising its accurate handling of the rolling window calculation, usefulness of the PDF report at borders, and the practical trip simulator for advance planning.
