How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Zillow has the largest home search audience and the strongest saved-search alerts, making it the best starting point for most buyers.
- Realtor.com pulls listings directly from MLS feeds, so its listing status is often the most current of the big portals.
- Redfin pairs fast listing updates with its own brokerage, tour scheduling and a lower listing fee for sellers in its markets.
- Trulia is the best pick for neighborhood research, with resident reviews, local photos and lifestyle filters.
- Homesnap adds a feature the others lack: photograph a house you are driving past and pull up its details.

The best realtor apps to use

Zillow is where most buyers start, and that scale is useful in itself. The app covers homes for sale, rentals, off-market properties and for-sale-by-owner listings, with map search, draw-your-own-boundary search and saved searches that alert you within minutes of a new listing or price change in your chosen area. The Zestimate gives an algorithmic value estimate for nearly every residential address, which is handy as a rough starting point when you are comparing neighborhoods.
The known weakness is data freshness. A home that went under contract in the morning can still show as active on Zillow later the same day, because Zillow aggregates feeds rather than pulling every status change instantly from the MLS. The Zestimate is also an estimate, not a valuation, and it can miss by a wide margin on unusual homes. Use Zillow to discover homes and track prices, then confirm availability and value with a local agent before making decisions.
What we like- Largest listing audience and inventory
- Strong saved searches and alerts
- Zestimate value estimates for most homes
Watch out for- Listing status can lag behind the MLS
- Contact buttons often route to paid Premier Agents

Redfin runs its own brokerage, and that shows up in the app in useful ways. Listing data refreshes faster than on most portals, tour scheduling is built in rather than bolted on, and the Redfin Estimate gives a second opinion on value alongside days-on-market and sold-comp filters. For sellers in Redfin markets, the listing fee is commonly lower than a traditional commission, often quoted around 1 to 1.5 percent versus the usual 2.5 to 3 percent for the listing side.
The trade is that Redfin is a product and a sales channel at once. When you tap to contact an agent, you are usually routed to a salaried Redfin agent, not the listing agent, and service quality varies by city depending on local staffing. If you want a specific independent agent, you may prefer a portal that routes differently. For buyers who want speed, clean data and easy tours, Redfin is the strongest all-round alternative to Zillow.
What we like- Fast listing updates
- Easy online tour scheduling
- Lower listing fees for sellers in served markets
Watch out for- Brokerage coverage varies by city
- The app is also a sales channel for its own agents

Realtor.com is the app to check when the question is whether a home is genuinely still available. Because it pulls directly from MLS feeds, its listing status is generally the most current of the three big portals, and that matters in a fast market where a day of stale data can mean a wasted tour. Each listing carries deep detail, including school information, crime data, commute estimates and an affordability calculator that ties price to monthly payment.
The app itself is less refined than Zillow's. Saved searches and alerts work, but the experience feels plainer, and the valuation tool does not outperform Zillow's Zestimate or Redfin's estimate in any consistent way. The smart way to use Realtor.com is as a verification tool. Find homes on any portal, then check Realtor.com for status before you call an agent or book a tour.
What we like- Direct MLS feeds for current status
- Deep per-listing data on schools, crime and commute
- Affordability calculator
Watch out for- Search and alert experience feels less polished
- Valuation tool is not stronger than rivals

Trulia is owned by Zillow Group, so its listings overlap heavily with Zillow's. What sets it apart is neighborhood context. Resident reviews, original neighborhood photos, drone footage in some areas, crime maps, school ratings and lifestyle filters help you judge what living somewhere actually feels like, not just what the house looks like. With more than 35 filters, you can narrow by commute time, pet policy, parking, price cuts and more.
Because Trulia shares Zillow's feed, it inherits the same freshness weakness. A home can show as available after it has gone pending, so confirm status elsewhere before visiting. Trulia earns its place as a second app for the research phase. Use it to compare neighborhoods and shortlist areas, then use Zillow, Redfin or Realtor.com to track the specific homes.
What we like- Resident reviews and local photos
- More than 35 search filters
- Neighborhood lifestyle data
Watch out for- Shares Zillow's listing feed, so status can lag
- Fewer off-market listings than Zillow itself

Homes.com has rebuilt itself around a simple promise: when you contact an agent through a listing, you reach the listing agent, not a paying advertiser. That matters if you want to talk to the person who actually knows the home. The app also stands out for neighborhood video tours and insights covering tens of thousands of areas, which give a better sense of streets, shops and schools than photos alone.
The audience is smaller than the big three, which means fewer user reviews and less community content on some listings. Saved search and alert tools exist but are less developed than Zillow's. Homes.com fits best as a complement for buyers who care about reaching the listing agent directly and who want video-led neighborhood research before committing to tours.
What we like- Neighborhood video tours for thousands of areas
- Listings route to the listing agent
- Detailed market data
Watch out for- Smaller audience than Zillow or Realtor.com
- Fewer app-only features for saved searches

Apartments.com is the rental specialist on this list, with more than a million apartments, houses, condos and townhomes for rent. For renters, that depth matters more than any buying feature. Listings include photos, floor plans, amenities, pet policies and fees, and many offer Matterport 3D tours. You can apply online, sign a lease digitally and pay rent through the platform in many cases, which keeps the whole process in one place.
The obvious limit is scope. Apartments.com will not help you buy a home or estimate a sale price, so buyers should look elsewhere. Listing quality also varies, since landlords write their own descriptions and some leave details thin. For renters, though, it is the deepest starting point, and pairing it with a buying portal only makes sense once you switch from renting to buying.
What we like- Largest dedicated rental inventory
- Online applications and rent payment
- 3D tours on many listings
Watch out for- Focused on rentals, so it is not a buying tool
- Listing quality varies by landlord

Homesnap does one thing the big portals do not. When you are driving through a neighborhood and see a house you like, you can photograph it in the app and pull up its listing details and public record information. For buyers who explore areas in person before committing to a search, that is genuinely useful, and it turns a casual drive into a shortlist. The app also supports messaging with agents and standard saved searches.
The catch is regional variation. Coverage and data freshness differ by market, so Homesnap works better as a discovery companion than as your only search tool. Its feature set is also narrower than Zillow or Redfin for filtering, alerts and market data. Keep Homesnap on your phone for drive-around days, and keep a big portal for the daily search.
What we like- Snap a photo of a house to see its details
- Quick access to property records
- Messaging with agents
Watch out for- Coverage and data freshness vary by region
- Smaller feature set than the big portals
How we chose
We compared these apps on listing inventory and freshness, search and alert quality, neighborhood and valuation data, agent contact routing, rental versus buying coverage, and app usability. We read each vendor's own homepage, plus recent independent comparisons of portal traffic and listing sources, and we favored apps that are free, available today and widely used in the United States. We did not claim hands-on testing, and we did not rank on visitor counts alone, since a large audience does not guarantee current data.
Using realtor apps without getting misled
The biggest trap with realtor apps is treating a portal as the market itself. Portals aggregate, estimate and advertise, and each one has commercial reasons for what it shows first. A home value estimate is an algorithm's guess, not an appraisal, and it can be off by thousands of dollars on renovated, unusual or rural homes. A listing that looks available may already be pending. Treat every app as a starting point, then verify status, price and condition with a local agent and, when it matters, a formal valuation.
Set up alerts the right way
Create one saved search per area and price band rather than one broad search for a whole city. Narrow alerts arrive faster and are easier to act on, and you will notice price cuts and new listings sooner. Turn on push alerts for new listings in your top area, but keep email alerts for wider searches so your phone does not become noise.
Know who answers when you tap contact
On Zillow, the contact button often routes to a Premier Agent who paid for that ZIP code, not the listing agent. On Homes.com, it routes to the listing agent. On Redfin, it routes to a Redfin agent. None of these is wrong, but the difference matters when you want local knowledge of a specific home. If you already work with an agent, tell them which homes interest you directly instead of tapping contact buttons at random.
Visit before you decide
Photos, 3D tours and neighborhood videos narrow the field, but they cannot show noise, light at different times of day, parking pressure or the feel of a street. Shortlist on the apps, then visit in person, ideally more than once. The apps save time by filtering out poor fits, and visits protect you from the fits that only look good on screen.
Frequently asked questions
Which realtor app is best for buying a home?
Zillow is the best starting point for most buyers because of its inventory and alerts, with Redfin close behind for fast updates and tour booking. Realtor.com is the best check for whether a listing is still available. Most buyers end up using two apps: one for discovery and one for verification.
Are home value estimates on these apps accurate?
They are rough guides, not valuations. Estimates use public records, recent sales and listing data, and they struggle with renovations, unusual layouts and thin markets. For a pricing decision, ask a local agent for a comparative market analysis or pay for an appraisal.
Do I need a realtor to use these apps?
No. Anyone can search, save homes and set alerts for free. An agent becomes valuable when you tour, negotiate, handle paperwork and interpret local market conditions. The apps help you find homes, and an agent helps you buy one well.
Which app is best for renting?
Apartments.com has the largest dedicated rental inventory and supports applications, digital leases and rent payment in many cases. Zillow and Trulia also list rentals, so renters often check both a rental specialist and a general portal.
Why does a home show as available on one app but pending on another?
Portals update at different speeds and from different feeds. Realtor.com pulls directly from MLS feeds and usually updates fastest, while aggregators can lag by hours. Always confirm status with the listing agent or on the MLS-fed portal before booking a tour.
