How Flags builds your Schengen travel history

Flags: Schengen Calculator is built around one record: the days you spent inside the Schengen Area. It can start that record from photo metadata already on your iPhone, and you can correct or complete it with manual stays. The result is a travel history you can inspect before using it for planning.

What the app uses

The app can use the date and location information available with photos in your library to suggest travel history. It does not need a live GPS trail to do that. A suggested trip is still a record for you to check: photos can be missing, location information can be absent, and a photo alone is not proof of immigration status.

Think of photo information as a starting point, not a decision. A single image can prompt you to remember an otherwise forgotten journey, but it may not tell you the exact dates of every stay. Review the period around each trip, particularly when a future plan is near a limit.

What you can correct

You can add or correct stays manually. This matters for phone-free trips, days without photos, or any trip where the photo record is incomplete. It also lets you correct a stay if the suggested date range is broader or narrower than the journey you actually made.

Manual review is especially important for arrival and departure dates. Under the ordinary short-stay calculation, those dates can affect the day total. The guide to manual stays and corrections gives a practical review sequence, and what counts as a day explains the standard rule.

What the app answers

With a complete stay history, Flags shows a rolling day count and can help you plan a future stay. Use it to make the record visible and to identify dates that need a closer check; do not treat it as a travel authorisation or legal conclusion.

Keep your own tickets, entry records and other documents when formal proof matters. Read the 90/180 calculation scope before relying on the count for a trip, and check the current official guidance when you travel. Flags is a tool, not legal advice — the border officer has the final say.
