At a Christie's International Real Estate open house, the people who walk through the door are exactly the kind you cannot afford to lose to an illegible clipboard — or to a "free" app that quietly forwards their phone number somewhere else. A Christie's International Real Estate open house sign-in sheet that lives on your iPad should do two things impeccably: capture each visitor cleanly, and keep what you capture entirely yours. OpenHouse was built around that second point.
This is an independent app, not a Christie's product. But discretion is its first principle, which is why it suits agents working at the top of the market.
Privacy is the point, not a feature
Most open house apps are cloud services: the visitor's name and number travel to a vendor's servers, sometimes to a paired lender, and you take their privacy on faith. OpenHouse takes a different path. It makes zero network calls. Every sign-in is written to the iPad in front of you and stays on the device until you decide to export it. Nothing is uploaded, nothing is synced, nothing is sold. For a buyer touring an eight-figure listing, that is not a nicety — it is the difference between trusting your sign-in and writing "n/a" in the phone field.
If you want the wider landscape first, our best open house apps list is honest about where each tool — including ours — makes its money, and OpenHouse vs Curb Hero explains why "free" usually means your visitor's data has a second audience.
Reliable at a remote or vacant estate
Trophy properties are precisely the ones with no signal — gated, rural, newly built, or simply empty. A cloud-first app degrades there into a queue-and-hope state. Because OpenHouse runs entirely offline, a listing with no Wi-Fi behaves exactly like a connected one: the form, the qualification, and the capture all happen on-device, instantly, every time.
Qualify quietly, then follow up well
Each visitor can be tagged the moment they finish — represented buyer, unrepresented hot lead, neighbor, or investor — so the people worth a personal call rise to the top without any awkward interrogation at the door. After the showing, you export on your terms — CSV, Contacts, vCard, a seller-ready PDF, or a share-to-CRM handoff — and your own follow-up takes over. Our guide to open house follow-up is a good companion for making the first touch feel personal rather than automated.
Signed disclosures for high-value transactions
When the stakes are high, what a visitor agreed to at the door is worth documenting. OpenHouse can present a disclosure or agency notice before sign-in and capture a signature, recording the acceptance with a timestamp on each lead. For the background on what belongs in that notice, see buyer-agency disclosure at open houses.
An understated kiosk
Add a discreet mark and a short welcome line, switch on kiosk mode, and the iPad presents one elegant sign-in screen — nothing else. No system settings to fumble, no chance of a guest wandering into your files between viewings.

The candid part: OpenHouse is a paid app ($9.99/month or $79.99/year, with a one-month free trial), it is iOS and iPadOS only, and it is deliberately not a marketing platform. It captures and qualifies at the door with absolute discretion, then hands the leads to your system. If that is the trade you want, try it free for a month and judge it at a single quiet showing before a marquee one.
Frequently asked questions
Is there an open house sign-in app for Christie's International Real Estate agents?
Yes. OpenHouse is an iPad and iPhone open house sign-in app any Christie's International Real Estate agent can use. It captures and qualifies each visitor at the door and keeps the leads on your own device, so a private client's details are never routed to a vendor cloud or a lender. It is an independent app and is not affiliated with Christie's International Real Estate.
Will my clients' visitor data stay private?
Yes — that is the entire design. OpenHouse makes no network calls and stores every sign-in on the iPad itself. Nothing is uploaded, synced, sold, or shared with a third party. A visitor's name and number leave the device only when you choose to export them, which matters a great deal at a discreet, high-value listing.
Does it work at a remote estate with no Wi-Fi?
Yes. Because OpenHouse is fully on-device, a gated estate or a vacant trophy property with no signal behaves exactly like a connected one. The sign-in, qualification, and capture all happen locally, with nothing waiting on a connection.
Can I present a disclosure or NDA-style notice before sign-in?
Yes. You can show a disclosure or agency notice before a visitor signs in and capture their signature, and each lead records that the disclosure was accepted with a timestamp — useful documentation for high-value transactions.
Can I keep the kiosk understated and on-brand?
Yes. You can add your own photo or mark and a brief welcome message and run it in built-in kiosk mode, so the iPad shows a single, elegant sign-in screen and nothing else — no clutter, no wandering into the rest of your device.
