What do I need to get right about collecting visitor contact details?

Consent and deletion, deliberately rather than accidentally. You are collecting real contact details from members of the public on a borrowed device, so show a plain-language line saying who gets the data and what it is used for, record that the visitor agreed, and give the agent a way to delete a lead outright. Rules vary by region and change, so let the agent edit the disclosure text rather than hardcoding one country's wording, and tell them to check their local requirements.

Why does kiosk mode need to be more than a screen?

Because the phone leaves the agent's hand. If a visitor can swipe back into the app, they see every other lead, including their competition for the house and other people's phone numbers. Kiosk mode should disable the back gesture, hide navigation entirely, and require a PIN to exit — and you should test it by actively trying to escape, not by assuming nobody will.

What a open house lead capture app needs

Kiosk mode — visitor sign-in only, locked to one property
Twenty-second capture: name, phone, email, buying timeline
Automatic follow-up reminder the evening of the open house
Per-property visitor list with notes added after the fact
One-tap call, text, or email from a lead record
Export leads as CSV for the agent's existing CRM

The screens

Screen	What it does
Properties	Listings with date, address, and visitor count
Kiosk Sign-In	Locked visitor form, PIN required to exit
Visitors	Everyone who signed in at one open house
Lead Detail	Contact, notes, follow-up state, call and text buttons
Follow-Ups	Leads due for contact today, oldest first
Settings	Kiosk PIN, form fields, export, disclosure text

The data model

Property: address, listPrice, openHouseDate, startTime, endTime, agentId
Visitor: propertyId, name, phone, email, timeline, workingWithAgent, signedInAt, consentGiven
Note: visitorId, body, createdAt
FollowUp: visitorId, dueDate, method, completed, outcome

The build prompt (copy this)

Paste this into ShipNative and it becomes a working React Native app with these screens, navigable in a live preview, in about two minutes:

“A lead capture app for real estate agents running open houses. The agent creates a property with an address, price, and open house date, then hands the phone to visitors in a kiosk mode that shows only the sign-in form and requires a PIN to exit — visitors must never be able to reach the agent's other data. The sign-in form is deliberately short: name, phone, email, buying timeline, and whether they already work with an agent, plus a consent checkbox with configurable disclosure text. Each sign-in creates a lead, and the app schedules a follow-up reminder for that evening. A Follow-Ups screen lists leads due for contact today, oldest first, and a lead detail screen has one-tap call, text, and email buttons plus a notes field the agent fills in afterwards. Visitors are grouped by property so the agent can see how a listing performed. Settings has the kiosk PIN, which form fields are required, and a CSV export. Screens: Properties, Kiosk Sign-In, Visitors, Lead Detail, Follow-Ups, Settings.”

Then iterate with small, screen-specific prompts (“make the primary button bigger”, “add an empty state”), preview on your own phone, and export the full Expo project whenever you want. The full method: how to build an app with AI.

How it makes money

Subscription of around $10–20 per month per agent — this app makes its user money directly, so it supports a price a consumer app never could. Sell it per agent, not per brokerage, until a brokerage asks. Free tier of one property so an agent can test it at a real open house before paying.

Implementation and the revenue math for every model: how to make money from an app. When you’re ready to ship: App Store and Google Play publishing guides.
