Free, with a one-time Border Days Pro. No subscription, no ads and no account. Your stays stay on your device.

Frequently asked questions

How does the 90/180 count work?
For the Schengen area, Border Days looks at the 180-day window that ends today and counts every day you were inside the area during it. If that number reaches 90, you have used your allowance. The window moves forward one day at a time, so days drop out of the count as they fall more than 180 days behind you. Cyprus works the same way.
Why do both the arrival day and the departure day count?
Because the Schengen rules count them. Any part of a day spent in the area is a day in the area, so the day you arrive and the day you leave are both included in your total. Border Days does the same so that its numbers match how the rules are applied.
What do "leave by" and "safe to re-enter" mean?
Leave by is the last day you can be in the area without going over the limit. Safe to re-enter is the date it is safe to come back after you have left. The app also shows when the full 90 days are available again. All of these dates follow the stays you have added.
How do I add my stays?
Two ways. You can add a stay by hand: pick the country, the arrival date and the departure date, or choose "still there" if you have not left yet. Or you can turn on automatic tracking, and Border Days works out which country you are in and records the stay for you. Automatic tracking is optional: you can use the app without it by adding stays by hand.
What does automatic tracking use, and which location permission should I pick?
It uses low-power location (significant location changes and visits, not continuous GPS) together with a map of every border that is built into the app, so your position becomes a country on your device, offline. "While Using" works. "Always" lets Border Days notice a border crossing on its own. You can change the permission at any time in iOS Settings.
An automatic crossing is wrong. How do I fix it?
You can undo an automatic crossing. You can also open Trips and edit the stay. Your counters and your leave-by date follow the corrected stays.
What about overnight flights?
The day you travel counts for both countries. After an overnight flight, check the date you left: one day can change your total, so make sure the departure date you entered is the day you actually left.
What is the airport transit option?
When you add a stay by hand there is an airport transit option, for times when you only changed planes. Rules for transit differ from country to country, so check the official source shown on the rule.
Which passports and countries are supported?
Border Days includes the Schengen area (90 days in any 180, for all non-EU passports), Cyprus (90 days in any 180), Ireland (90 days) and the United Kingdom (6 months per visit). Cyprus and Ireland are counted separately from Schengen. For US passports it also covers Japan, Thailand, Vietnam, South Korea, Mexico, Canada, Australia, Indonesia, the Philippines, Malaysia, Singapore, Turkey and the UAE. EU, EEA and Swiss passports have free movement, so no limit is counted for them in Schengen, Cyprus or Ireland, and UK and Irish citizens are exempt from each other's limits (the Common Travel Area). More destinations are coming.
Can I trust the rules?
Every rule shows its official source and the date it was last checked, and the link opens in your browser. Border Days is not legal advice. Entry rules can change and can depend on your situation, so always confirm with the official source before you travel.
What alerts does Border Days send?
Local notifications 30, 14, 7, 3 and 1 days before your leave-by date, and one when you cross a border. They are generated on your device. If they do not arrive, check that notifications are allowed for Border Days in iOS Settings.
What does Border Days Pro include, and is it a subscription?
No subscription. Border Days Pro is a single purchase of $9.99. It adds a trip planner (check future dates before you book, and see the days you would have to spare or the latest day you could stay), several passports (for dual citizens, the most generous rule wins) and a PDF travel report for each year (days per country plus every stay, for a visa office or your accountant, made from Settings > Your records). Everything else is free. There is also a free 3-day Pro trial: it asks for no payment details, nothing renews, and afterwards the app goes back to the free tier and keeps everything you entered.
How do I restore Border Days Pro?
Open the Pro paywall and tap Restore Purchase. Use the same Apple Account you bought it with, and make sure you are online. If it still does not come back, email us and we will sort it out.
Are there widgets?
Yes. Lock Screen and Home Screen widgets show your days left and your leave-by date.
How do I export my data?
You can export a readable JSON file of your stays to Files or iCloud Drive at any time. The file goes where you choose, and it is yours to keep.
How do I use it on iPhone Duo?
Unfolded, you see two panes side by side, with an on-screen control to swap them. Half-folded like a laptop, the map is on top and the counters are below. In tent mode you get one big counter. The app also works on iPhone and iPad.
Which languages does it speak?
English, Spanish, French, German, Italian, Portuguese (Brazil), Polish, Russian, Turkish, Arabic, Hindi, Chinese (Simplified and Traditional), Japanese, Korean, Vietnamese, Thai and Indonesian.
How do I send feedback?
Open Settings in the app and tap Send Feedback. It opens an email to borderdays@agenticquarks.com with your app version, build and iOS version, and nothing else.
