Questions

What is an event check-in app?

An event check-in app replaces a paper guestlist at the door. Guests show a QR code, staff scan it with a phone and the app marks them as arrived, blocks duplicate entries and shows live attendance.

Is theguests.app free?

Yes. Unlimited events, unlimited guests and unlimited door crew are free.

Do I need a scanner or special hardware?

No. Any iPhone, Android phone or tablet with a camera works as the scanner.

What happens if there is no internet at the venue?

Check-in continues offline and syncs automatically once the connection returns.

Who is it for?

Clubs, promoters, festivals, private parties, conferences, product launches and tours that need a fast, reliable door.
