VisaNudge reminds you when you need to leave a country, so you never overstay by accident.

Tell VisaNudge when you arrived and how long you're allowed to stay. It works out your last permitted day and reminds you 30, 14, 7, 3 and 1 day before, and on the day itself.

HOW IT WORKS • Pick the country, the day you arrived and how long you can stay. If your visa or stamp shows a last day, enter that instead. • See how many days you have left at a glance, with every upcoming reminder listed. • Reminders arrive at the time you choose, in the local time of the country you're staying in, so travelling across time zones never moves your deadline.

THE DETAILS THAT CATCH PEOPLE OUT • Day one isn't always the day you land. In China, your stay is counted from the day after you arrive. VisaNudge uses China's rule and, for other countries, assumes the stricter rule that the day you arrive counts as day 1, so a deadline is never later than it should be. • More than one passport? What you're allowed depends on the passport you showed at the border. Add all your nationalities and choose the one you entered with. • Country notes explain dates that confuse people, like a visa's "enter before" date, which isn't the day you must leave.

NOTICES WHEN YOU CROSS A BORDER When your phone connects to a mobile network in another country, VisaNudge asks whether you've left and offers to set up reminders for the new country. It never ends a stay or cancels reminders without asking.

PRIVATE BY DESIGN • No account, no servers, no ads, no tracking. • Everything stays on your phone. The app doesn't even have permission to use the internet. • Location is optional and only used while the app is open, to tell which country you're in. Only the country is kept.
