Since its launch in October 2025, the European Union’s Entry-Exit System (EES) has sparked controversy due to reported long airport queues and confusion among travelers. Although not fully operational until April 10, the EES is already causing issues for holidaymakers, especially concerning the 90-day rule.
George Cremer, a digital nomad and software developer, has developed an app called Schengen Simple to assist non-EU nationals, including Brits, in navigating the 90/180-day rule within the Schengen Area. The system tracks entries and exits digitally, flagging overstays automatically and catching out individuals who unknowingly violate the rule.
According to George, many people make mistakes with the 90-day rule by not understanding its rolling window concept. Contrary to popular belief, the 90 days do not reset upon leaving and re-entering the area. Additionally, all 29 Schengen countries share a common 90-day limit, with the 180-day calculation counting backward from each day, not split into specific calendar periods.
As the travel season intensifies with Easter and summer approaching, travelers are advised to plan ahead to avoid exceeding their allowed stay. George emphasized the importance of foresight in managing travel plans to prevent running short on allowable days for future trips. Schengen Simple aims to provide users with a clear view of their remaining days to facilitate informed decision-making when booking holidays.
