Curb Hero vs Open Home Pro vs Spacio was one of the most-searched comparisons in this category for years, because those three apps divided the market between them. In 2026 the comparison got more complicated. Spacio's App Store listing went dark on January 12, 2026, so you can no longer install it on a new device. That changes the job this page does: it is now partly a historical accounting of what Spacio was, partly an honest head-to-head between the two apps that are still live, and partly a look at what agents do next when neither of those fits. This is a neutral comparison. We make OpenHouse, which is none of the three apps above, and we seat it at the end as a fourth option. Our interest is in giving you a fair read so you pick the right tool, even if that is not ours.
The three apps in brief
Before the table, a sentence on each.
Curb Hero is free for agents, genuinely polished, and the most widely used digital sign-in tool in the category. It earns its 4.9-star rating across a large review base. It is funded through lender co-marketing rather than agent subscriptions.
Open Home Pro is the category's veteran. It has been around since the early years of open house sign-in apps, runs on tablets (iPad and Android tablet), and takes a paid subscription model. Sign-in happens on the tablet; leads sync to the cloud afterward.
Spacio (a HomeSpotter / Lone Wolf product) was a paid, cloud-platform sign-in app with social-profile enrichment and deep CRM sync as its calling cards. Its final public reviews slid to around 2.8 stars amid crash and sign-up complaints. As of January 12, 2026, it is no longer available to download.

Curb Hero: what it does and what it costs you
Curb Hero is the category leader for a real reason. At zero agent cost, it covers the core job well: branded sign-in, QR code check-in, single-property pages, and a clean export. The company has invested in the product and shows it in the rating. For many agents, especially those already co-marketing with a preferred lender, this is the obvious answer.
The trade-off is structural. Curb Hero is funded by lender co-marketing, and Curb Hero's own help center explains that a default lender may be assigned to your listings and that lead data is shared with that lender when visitors opt into mortgage questions. That is the business model, and it is transparent about it. Whether it is a problem depends on your situation. Agents already working with a specific lender partner, and who route mortgage referrals that way anyway, often find it fits naturally. Agents who want a clean wall between their visitor data and any third party will weigh it differently.
The offline question is also worth asking directly. Curb Hero functions in a sync-later mode when a connection drops, capturing sign-ins locally and uploading when connectivity returns. In most suburban listings with decent LTE that is not an issue. In the concrete-walled vacant property with the cancelled internet subscription, your sign-ins are in a queue that may or may not flush by the time you're packing up. Most agents report it works fine. The minority who have had sync failures at busy events tend to remember it.

Open Home Pro: the long-running tablet option
Open Home Pro has a track record that most apps in this category cannot match. Agents have run thousands of events on it without significant drama, and that longevity matters when you are handing your visitor list to a piece of software in a stranger's house.
The tablet-only design is both a feature and a constraint. Running sign-in from a dedicated iPad keeps the experience clean for visitors and keeps your phone available for agent work. It also means if your iPad battery dies at hour two of a Sunday event with no charger nearby, you are on paper. There is no phone fallback built into the workflow the way there is with an app designed to run on whatever device you grab.
Offline handling on Open Home Pro is a sync-later model: sign-ins are captured and held on the device when the network is down, then uploaded when it reconnects. Similar to Curb Hero in that respect, and with the same asterisk that "sync-later" introduces a step that could fail. For most agents it does not fail. For agents at listings with genuinely poor connectivity, rural properties, new construction in a signal dead zone, concrete buildings, it is something to test before trusting on a high-traffic Sunday.
Open Home Pro's pricing lives on their site and we will not quote numbers that may have changed since we last checked. What is clear is that it is a subscription product, agent-paid, without the lender co-marketing structure that funds Curb Hero.

What happened to Spacio
Spacio deserves a full section because plenty of agents are still looking for it or dealing with the aftermath of it going away.
Spacio was the open house sign-in product from HomeSpotter, which became part of Lone Wolf Technologies. On January 12, 2026, the iOS app was removed from the Apple App Store. Its former App Store listing exists but no longer offers a download. Public reviews on that listing trended downward through 2025, landing around 2.8 stars in their final stretch, with crash reports and account-creation complaints appearing repeatedly.
The app had two genuinely useful features that neither Curb Hero nor Open Home Pro replicated: social-profile enrichment (appending public social and professional data to a visitor's sign-in record) and deep two-way CRM sync (a live connection into the CRM, not just an export). For agents whose workflow depended on one of those, the removal created a real gap, not just an inconvenience.
If you still have Spacio installed on an older iPad, your immediate priority is exporting your lead history. The installed copy may still open, but future iPadOS updates will eventually break compatibility, and the window for a clean export is finite. There is a dedicated guide at Spacio alternatives that covers the field if you are still shopping for a replacement.
We don't know the internal reasons for Spacio's removal. We are not going to speculate about servers or timelines we cannot verify. The practical fact is the same either way: it cannot be installed, it is not being updated, and it will stop working on current hardware in due course.
Offline reliability: what the differences actually mean on a Sunday
This question shows up in every comparison of these tools because it is the one that bites agents at the worst time. Here is how the three apps actually differ, without spin.
Curb Hero and Open Home Pro both use variations of sync-later offline handling. Sign-ins captured without connectivity are held on the device and uploaded when the connection returns. In practice, for the majority of listings with at least a few bars of LTE, this works without issues. The risk is narrow but real: a listing in a cellular dead zone (not uncommon in rural areas, new construction, or dense urban concrete buildings) can result in a queue that does not flush cleanly, especially if the app is closed before sync completes.
Spacio was a cloud platform and leaned on connectivity more heavily. When it worked, the richer feature set, enrichment, live CRM sync, depended on network access. That architecture also meant the platform's availability depended entirely on the vendor staying in business and keeping the service running.
Both offline-capable models (sync-later for Curb Hero and Open Home Pro) are meaningfully better than clipboard paper for most agents. But agents who work frequently in connectivity dead zones may want to test specifically at a problematic listing before settling on either. Run the app with airplane mode on and confirm your sign-ins are actually on the device before you trust it at a busy event.
This is where OpenHouse differs, which we cover below.
What agents do when none of these fit
The Curb Hero vs Open Home Pro vs Spacio comparison is the one people run because those were the three names that dominated the category. But it is worth stepping back and asking whether the right answer is one of those three or something built on different principles.
The pattern we see repeatedly in agent conversations: Curb Hero is right for agents who accept the lender co-marketing trade-off and want a free, polished app. Open Home Pro is right for agents who want a subscription-paid tablet app with a long track record and no lender data sharing. Spacio is gone.
The agents who land on neither are usually solving for one of two things: true offline reliability (not sync-later, but an app that never makes a network call at any stage) or a harder wall between visitor data and any third party. Those are not complaints about Curb Hero or Open Home Pro specifically; they are different priorities that led to a different architectural choice.
OpenHouse: the offline-first, privacy-by-architecture alternative
We build OpenHouse, so you should apply a discount to what follows. The architecture facts are verifiable by testing the app.
OpenHouse makes zero network calls. Not sync-later. Not "works offline and uploads when you reconnect." Nothing that leaves the device, ever, unless you explicitly export it. Every sign-in is written to local storage on the iPad, qualified at capture (represented buyer, unrepresented lead, neighbor, investor, or incomplete), and held there until you choose an export path: CSV, PDF, Contacts, vCard, or a share into the CRM you already use. There is no account, so there is nothing to log into at the door, and no cloud account for a vendor acquisition or shutdown to affect. The failure mode that removed Spacio from agents' workflows cannot happen here because there is no backend to take offline.
A few specifics worth knowing:
- Pricing: $9.99/month or $79.99/year with a one-month free trial.
- Platform: iOS and iPadOS only. No Android, no browser sign-in. That is a real constraint if your team uses a mix of devices.
- If a subscription lapses: read-only mode. Every lead you captured stays viewable and exportable. Nothing is deleted or held hostage; you just cannot run new events until you renew.
- No lender co-marketing. Visitor data has no second audience by design.
- No social-profile enrichment. The information you get is what the visitor typed, nothing pulled from data brokers. That is a deliberate choice, not a gap.
- Built-in kiosk mode. The app locks down the iPad for visitor sign-in without requiring Apple's Guided Access configuration, though that works too if you prefer it.
Where we land honestly in the Curb Hero vs Open Home Pro vs Spacio conversation: OpenHouse is not a replacement for what Spacio did well (enrichment and live CRM sync), and it is not free the way Curb Hero is. It is a focused, paid offline-capture tool for agents who want the data on their device and want to know exactly where it goes.

Who should pick each app
Strip the feature lists and it comes down to what you are willing to trade.
Choose Curb Hero if:
- Free is a real requirement, not a preference
- You already co-market with a lender or are fine with the co-marketing arrangement
- You want a polished, widely-used app with a large review base and QR sign-in
Choose Open Home Pro if:
- You want a paid subscription app with no lender co-marketing
- A long track record and tablet-focused design fits your workflow
- You work mainly at listings with reliable connectivity
Do not install Spacio:
- The app is no longer available. If you are a former user, focus on exporting your data. The Spacio alternatives guide covers replacements.
Consider OpenHouse if:
- Offline-first (no network calls, not sync-later) is a priority, rural listings, new construction, dead-zone properties
- You want visitor data to stay on your device with no third-party audience
- You want a read-only data guarantee if you ever stop paying
- You are fine paying $9.99/month for a narrower, focused tool
Try whichever you land on at a low-stakes event first. Sign yourself in, kill the Wi-Fi, and walk through the export before you trust it on a busy Sunday. Roundups by outlets like The Close and HousingWire keep landing on the same point: the app you test before you need it is the one that actually works when you do. If OpenHouse looks like the right fit, the first month is free, try it at a real event and judge it on the kiosk.
Frequently asked questions
Is Spacio still available in 2026?
No. Spacio's iOS app was removed from the Apple App Store on January 12, 2026. The listing still exists but the app cannot be downloaded or reinstalled. Agents who still have Spacio on an old device should export their lead history before an iPadOS update breaks compatibility.
Is Curb Hero really free?
Yes, Curb Hero is free for agents. It is funded through lender co-marketing: a default lender can be assigned to your listings, and visitor data is shared with that lender when guests opt into mortgage questions. Curb Hero's own help center explains this arrangement.
Does Open Home Pro work offline?
Open Home Pro uses a sync-later offline model. Sign-ins captured without a connection are held on the device and uploaded when connectivity returns. That differs from a fully local app where no network call is ever made, at any stage.
Which open house app is best for privacy?
That depends on your definition. Curb Hero shares lead data with a paired lender under its co-marketing model. Open Home Pro syncs to a cloud account. Spacio is no longer available. OpenHouse keeps leads on the device by design, making zero network calls, so visitor data never leaves the iPad unless you export it yourself.
What should Spacio users switch to?
The two live alternatives most agents look at are Curb Hero and Open Home Pro. Curb Hero is free with a lender co-marketing trade-off; Open Home Pro is a paid tablet app with a longer track record. OpenHouse is a third option built around offline capture and privacy if those priorities drive your search.
Can I compare Curb Hero and Open Home Pro on iPhone?
Curb Hero runs on iPhone, iPad, and through a web browser, giving you device flexibility. Open Home Pro is designed as a tablet-first sign-in experience and is not intended for phone use during an event. That difference matters if you work without a dedicated iPad.
