Schengen tracker for iPhone: your 90/180 count kept as you travel

How the 90 days in any 180 are counted

A visitor to the Schengen Area can stay up to 90 days in any 180-day period. The 180 days are not a fixed half year: on each day of a stay you count back 180 days and check that the Schengen days inside that window do not exceed 90. The Schengen Area is 29 countries: 25 EU member states plus Iceland, Norway, Switzerland and Liechtenstein. Ireland and Cyprus are outside it.^1,2

Geostay does that sum for you on the Schengen card, and every other rule you track has a card of its own. The date on this one to plan your next trip around is the day your earlier stays have all dropped out of the window, because that is when a full 90 days are available again.

If you hold a visa or a residence permit, add it to the same card with its validity dates, the duration of stay and the number of entries.

No trips to type in

Geostay records which country your iPhone is in, day by day, even when the app is closed. A short-stay calculator, such as the European Commission's, asks for the entry and exit dates of every previous stay and checks one date at a time, so each time you check you type every date in again from memory.¹

The country comes from a map stored in the app, so it works offline: roaming and flight mode leave no gap in the record. Geostay ignores location readings taken in the air or close to a border, so a country you only fly over is not recorded as a stay, and a drive along the border does not count as a visit.

Timeline shows every stay as a list or on a calendar. You can add a trip, change the country of a day or delete a day, and your own edits take precedence over what the phone recorded. The Schengen card works from the same record, so if you fix a day in Timeline, your days left update with it.

Your trips from before you installed the app

The window looks back 180 days, so a count that starts today is only right if it knows where you were for the past six months. Geostay rebuilds those months from your photo library or from a travel history you already keep.

Geostay reads your photos and files on the iPhone itself, so your travel history stays on the phone. Once your past trips are in, the count is right from the first day you use the app.

Warnings before you reach the 90-day limit

On a long stay, or at a second home you keep going back to, the day you have to leave is easy to lose track of. Geostay warns you ahead of it, in a notification that states the count and the date, such as "Staying past 4 Dec would cross the limit". You set how many days ahead it warns, so the message lands while there is still time to change a booking.

Geostay also reminds you before a permit ends, and lets you know when you can come back for a full 90 days. Each kind of warning and each card has its own on-off switch, and the Watching for you list on the Profile tab shows every card and how it warns you.

Between warnings, you can see the count without opening the app, through Geostay's widgets for the Home Screen and the Lock Screen. The Today widget shows one card with its count, so a glance at the phone gives you the Schengen number, and the Countries widget shows your most urgent cards.

Doesn't the Entry/Exit System count my days now?

It does, at the border. Since 10 April 2026 the Entry/Exit System has replaced passport stamping for non-EU nationals on a short stay: it records the date and place of each entry and exit at the external borders of the 29 countries using it, so an overstay is detected automatically.³

The EES also works out how long you are still allowed to stay, and there is a web service where you enter your details and the dates you plan to travel and get an OK or NOT OK answer with the stay you have left.⁴

Geostay keeps the count running from the days it has recorded, so well before you book anything you can see whether a week in May still leaves room for September, or how long you can stay this autumn.
