Open House Apps Cost $0 to $29 a Month. Pick the One That Syncs
Most agents pick an open house sign-in app the way they pick a pen: whatever's free and on the table. That's fine for the price, because the gap between the apps is small. For a solo agent, the published plans we found run from $0 to $29 a month. The expensive mistake is somewhere else. It's the visitor who signs in on an iPad at 2 p.m. and doesn't hear from you until Monday because the sign-in sat in an app that never talked to your CRM. So we set out to answer one question about open house apps for realtors: which ones put the lead where your follow-up already runs? On November 9, 2026 we pulled the pricing pages and App Store data for seven open house sign-in apps. Here's what we found, and the five-step setup that turns a sign-in into a same-day text.
Which Open House Sign-In App Should You Use?
Use the one that connects directly to the CRM you already pay for. Curb Hero is free for solo agents and lists Follow Up Boss among its native integrations. Happy Open House names Follow Up Boss and Top Producer. If your CRM isn't on an app's list, you're relying on Zapier or a CSV export, and that delay costs more than any subscription.
The ranking flips depending on your CRM, which is why "best open house app" lists rarely help. A Follow Up Boss agent has the most direct options. A BoldTrail agent has Inside Real Estate's own OpenHouse app, which keeps leads inside the platform but rates poorly with users. Everyone else should check the vendor's integration page for their CRM by name, not trust a line like "6000+ CRMs," which is how Curb Hero's pricing page describes its sync. That number includes Zapier connections, and Curb Hero's own homepage footer gives a different figure: "2000+ CRMs and marketing apps via Curb Hero's Zapier integration." A Zapier hop can work, but it's one more thing that can break on a Sunday, and you won't find out until a buyer mentions they never heard back.
How We Checked Them
We didn't run open houses for this. We read what each vendor publishes and what Apple's App Store data shows, all on the same day, so the comparison is apples to apples. For pricing, we used each vendor's own pricing page, plus the in-app purchase prices on the App Store listing where the page didn't match. For user sentiment, we pulled each iPhone app's average rating, ratings count and latest version date from Apple's App Store data. The version date matters more than most people think. An app that hasn't shipped an update in years is a warning sign for a tool that has to sync with a CRM that changes every quarter. For integrations, we only counted a CRM as supported if the vendor names it. "Integrates with your CRM" doesn't count. The seven apps were Curb Hero, Open Home Pro, Happy Open House, Spacio, Open House Wizard, BoldTrail OpenHouse and CORE Open House.
What the Seven Apps Cost and How Agents Rate Them
| App | Solo agent price | iPhone rating | Latest iPhone update | CRMs named |
|---|---|---|---|---|
| Curb Hero | Free | 4.9 (490) | Nov 5, 2026 | Follow Up Boss (native), Zapier |
| Open Home Pro | Free for 25 leads; Premium $24.99/mo or $239.99/yr in-app | 4.3 (1,008) | Nov 2, 2026 | None named ("Export leads") |
| Happy Open House | $29/mo or $199/yr | 3.2 (17) | May 11, 2018 | Follow Up Boss, Top Producer, others |
| Spacio (Lone Wolf) | Not listed; $150 one-time team branding fee | 2.6 (9) | Jan 30, 2026 | None named on page |
| BoldTrail OpenHouse | For BoldTrail users | 2.4 (11) | Oct 27, 2026 | BoldTrail |
| CORE Open House | For kvCORE users | 3.7 (58) | Jun 10, 2025 | kvCORE |
| Open House Wizard | Price not verified | 1.8 (5) | Mar 15, 2025 | Zapier only for Follow Up Boss |
Curb Hero is the standout on price. It's "100% free for solo agents," and the team plans are cheap per head: up to 10 agents costs $50 a month or $500 a year, 25 agents costs $100 a month or $1,000 a year, and 50 agents costs $150 a month or $1,500 a year, with a 30-day trial and "No contracts - cancel anytime." On a 10-agent team billed annually, that's $50 per agent per year. One caveat on its rating: Apple's App Store data returned a 4.9 average from 490 ratings, but the public listing page currently says the app "hasn't received enough ratings or reviews to display an overview," so treat that score as softer than the others. Open Home Pro has the deepest review base at 4.3 stars from 1,008 ratings. Its free plan lets you "View & Manage your first 25 leads," and Premium is $24.99 a month or $239.99 a year in the app, which works out to $20 a month and matches the "Save 20% annually" line on its pricing page.
What Surprised Us
The CRM-native apps rate worse than the free standalone one. BoldTrail OpenHouse holds 2.4 stars from 11 ratings, and kvCORE's CORE Open House sits at 3.7 stars from 58 ratings with no update since June 10, 2025. BoomTown's btPRO Open House listing has zero ratings and carries the same version number and date as CORE Open House, 3.0.26 from June 10, 2025, which suggests the same build under two names. If your brokerage is moving you from kvCORE or BoomTown to BoldTrail, your open house app is changing too. Our BoomTown vs kvCORE breakdown covers the rest of that move. The second surprise was how old some listings are. Happy Open House charges $29 a month, or $199 a year (about $16.58 a month), yet its iPhone app's latest version, 1.3, dates to May 11, 2018. Its pricing page also lists iOS, Android and mobile web apps, so test the version you'd actually use at the door before paying.
The Five-Step Setup That Turns a Sign-In Into a Same-Day Text
The app is only the first link. A sign-in turns into a conversation when the lead lands in your CRM tagged, assigned and already enrolled in follow-up. Speed is the whole game here, and our 15-minute lead response fix shows how much faster replies change outcomes. Here's the setup, which takes about half an hour once:
- Pick the app your CRM names. Follow Up Boss users have direct options in Curb Hero and Happy Open House. BoldTrail users can stay in-platform with BoldTrail OpenHouse. Anyone else should confirm their CRM by name on the vendor's integration page.
- Map your custom questions to CRM fields. "Working with an agent?" and "Pre-approved?" should land in fields you can filter on, not in a notes blob.
- Tag the source with the address. Use a source like "Open House, 123 Main St" so you can tell which listing and which weekend produced the lead.
- Trigger an automatic first touch. Enroll open house leads in an action plan that sends a thank-you text within minutes and assigns a call task for the same day. Our automated follow-up sequences guide has templates.
- Run a test sign-in the night before. Sign in as a fake visitor, then check that the contact appears in your CRM with the right tag and that the first text fires.
Our Verdict by CRM
If you're a solo agent on Follow Up Boss, start with Curb Hero. It's free, it names Follow Up Boss as a native integration, and its iPhone app shipped an update on November 5, 2026. If you're on BoldTrail, the in-platform OpenHouse app keeps leads where your action plans already run, which outweighs its 2.4-star rating as long as it syncs reliably in your test. If you're on a CRM no vendor names, Open Home Pro is the most-reviewed app in the group, but plan on exporting leads, since its description only says "Export leads to your CRM." Teams should price Curb Hero's annual tiers first, because $500 a year for up to 10 agents is hard to beat. If you're still choosing a CRM, check which open house apps connect to it before you sign. Our real estate CRM comparison is a good place to start.
