Best guest check-in and guest list apps.The door is the first impression.

If your guests already register through Ticket Tailor, Humanitix, Eventbrite or Luma, start with that platform’s own check-in app: none of their pricing pages sets a free-tier cap below 80 guests, and the guest list is already in it. If you only have a spreadsheet, Hi.Events’ free browser tool works without an account, but each device keeps its own list, so two door staff will not see each other’s check-ins.

Free check-in is not the same as free ticket sales: paid tickets still carry platform and card-processing fees. Run your trial on the plan you will actually use, after any premium trial ends. The table records what each company’s own pages said on October 6, 2026; it is not our test of their apps.

Only what each device already knows. A disconnected device can refuse a ticket it has already scanned itself, but it cannot know that the other disconnected device admitted the same ticket a minute ago, or that a ticket was refunded or cancelled after it last synced. Software that says it detects duplicates after reconnecting is reporting the problem, not preventing it.

Vendors document this plainly. zkipster says its offline devices do not communicate with each other or with the server, and asks you to reconnect them one at a time so their syncs do not compete. Hi.Events’ free tool never shares check-ins between devices. Ticket Tailor scans offline from a downloaded door list but needs a connection to sync. A refund is also a separate decision from admission: Ticket Tailor leaves a refunded ticket valid unless you also void it.

If entry must be exact during an outage, run one admitting device and have the second person handle questions, or split the list between devices. Ask any vendor to show you the following in a test event with made-up guests, on the plan you will buy.

Never let the iPad show a list. Ask each guest to type something that matches only them, such as a short personal code or their full name as an exact match, show at most a first name and last initial to confirm, and send anyone with no match or a shared name to a staff member instead of letting them pick from results.

A name alone cannot tell two Alex Johnsons apart, so plan a second detail (the email they registered with, or a code) or a person at the desk for those cases. Lock the iPad to the check-in app with Guided Access, which Apple documents as restricting the device to a single app, disabling chosen parts of the screen and requiring a passcode or Face ID to leave.

Some tools are built for this. OneTap documents a short code per person so the roster never appears on screen. Cvent describes a Secure Search setting that requires an exact match and does not auto-fill names; its kiosk mode needs a Premium license and does not run on phones. SocialLoop does not offer a self-service kiosk; its check-in is run by staff.

Plan for your busiest few minutes, not your guest count. Note when each guest joins the line and how long their check-in really takes, including the slow ones (no ticket, wrong email, paying at the door), then test how many lanes keep the longest wait acceptable.

At one or two events, have someone write down three times per guest: joining the line, reaching the table and leaving it. A scan timestamp alone shows only the last of these, so it hides the line when it is longest.

Illustrative example with made-up times: twelve guests arrive at seconds 0, 0, 5, 5, 10, 10, 15, 15, 20, 20, 25, 25. Ten check-ins take 8 seconds; one takes 60 and one takes 90 because of a problem. Each free lane takes the next guest in line.

SocialLoop fits when you want RSVPs, ticketing, the guest list and the door in one account. Its scanner checks each ticket against the live record at the moment of the scan. If a second device scans a ticket that was already admitted, staff see “Already checked in” with the time of the first scan; cancelled tickets and tickets for another event are refused.

You can invite door staff as Check-in Attendants, a role meant for check-in only: it cannot edit the guest list, issue refunds or see analytics. Afterwards you can export the guest list as a CSV that shows who checked in.

Three limits to weigh. The web scanner needs a connection. The iOS app’s Offline Mode keeps scanning when the signal drops if you open the scanner while still connected, so it can load the guest list; check-ins made offline are saved on the phone and sync when it reconnects, but, like any offline device, it cannot see what another offline device admitted. There is no self-service kiosk. And the Free plan covers 1 event per month and 1 invited staff member per event besides you, so a weekly event or two invited door staff needs a paid plan; see pricing. Run the duplicate and staff tests above before you rely on it.
