Zillow is the best overall real estate app for most home buyers and renters in the United States. It combines home and rental listings, detailed filters, map searches, saved searches, shared collections, virtual tours, agent connections and affordability tools in one app. Zillow also supports natural-language searches, such as finding homes near a particular commute, school or point of interest.
Redfin is a better fit for buyers who need fast listing alerts and in-app tour scheduling. Realtor.com is a strong option for MLS-focused searches, map tools and property research.
Best Realtor Apps at a Glance
| App | Best for | Main strengths | Important limitation |
|---|---|---|---|
| Zillow | Most buyers and renters | Broad search tools, rentals, map drawing, natural-language search, shared collections, virtual tours and affordability tools | A Zestimate is not a professional appraisal |
| Redfin | Competitive markets and fast tours | Frequent listing updates, real-time alerts, mortgage and monthly-cost tools, 3D tours and in-app tour scheduling | Tour availability depends on the property and agent |
| Realtor.com | MLS-focused research | Map Draw, school searches, 3D tours, price alerts, flood and noise map layers and affordability calculators | Its main strength is property search rather than transaction management |
Why Zillow Is the Best Overall Choice
Zillow covers the widest mix of common home-search tasks in one app.
You can use Zillow to:
- Search homes for sale and apartments for rent
- Draw a custom search area on a map
- Save listings and searches
- Share homes with a partner or family member
- View photos, property details and selected 3D tours
- Search with everyday language instead of preset filters
- Estimate affordability with Zillow's BuyAbility tools
- Request tours and connect with local agents
- Track parts of the buying process through Zillow's home-search tools
Zillow also connects search, affordability, financing and later transaction steps through shared collections and other personalized features.
The Main Zillow Warning
A Zestimate is not the confirmed market value of a property. Zillow describes it as a computer-generated estimate, not an appraisal. For a more reliable valuation, compare recent sales, request an agent's comparative market analysis or hire a professional appraiser.
Requesting an agent or tour through Zillow can also result in your contact details and search activity being shared with a real estate professional for follow-up.
Choose Redfin if Speed Matters Most
Redfin is the best alternative for buyers who want quick listing alerts and in-app tour scheduling.
Redfin promotes listing updates every two minutes. Its app also includes saved-search alerts, mortgage and monthly-payment calculations, 3D walkthroughs and direct tour scheduling. The App Store listing adds an important qualification: 50% of MLS listing updates received by Redfin post within two minutes. That means the two-minute figure does not apply to every listing.
Redfin is useful when:
- Homes in your area receive offers quickly
- You want alerts for new listings and price changes
- You want to book tours through a brokerage
- You want monthly costs to include taxes, insurance and HOA fees
- You prefer Redfin's agent and touring system
The app is free to download, but tour requests still depend on the property and agent's availability.
Choose Realtor.com for MLS-Focused Search and Map Research
Realtor.com is a strong choice when MLS data, map research and property-specific location details matter most.
The Realtor.com app includes:
- Custom map drawing
- School and school-boundary searches
- Price and monthly-payment searches
- 3D home tours
- Price-change and new-listing alerts
- Flood-risk and noise map layers
- Points-of-interest map layers
- Shared saved homes and comments
Realtor.com says its platform provides comprehensive for-sale listings and works with MLS partners to deliver MLS-sourced property information. Its app listing highlights map tools, alerts, 3D tours, affordability calculations and flood-risk information.
Realtor.com may be the better first app if you are:
- Comparing several neighborhoods
- Researching schools, noise or flood risk
- Watching price reductions
- Searching in an area where MLS data quality matters
- Working with an agent who prefers Realtor.com
The Best Setup for an Active Buyer
For most serious buyers, use the apps for different jobs:
- Use Zillow as your main search app.
- Add Redfin for fast alerts and tour scheduling.
- Check Realtor.com when a listing status or property detail needs confirmation.
- Confirm the current status with your buyer's agent before making an offer or arranging an inspection.
Using two or three apps can help because listing feeds, update timing, photos and property details may differ between platforms.
Best App by Situation
- Best overall: Zillow
- Best for renters: Zillow
- Best for fast-moving buyers: Redfin
- Best for scheduling tours: Redfin
- Best for map and neighborhood research: Realtor.com
- Best for school searches and property overlays: Realtor.com

- Best for estimating affordability: Zillow, Redfin or Realtor.com, with the figures verified by a lender
If You Mean an App for Real Estate Agents
If "realtor app" means an app for a licensed real estate professional rather than a home-search app, the choice changes.
- Realtor.com PRO is designed for lead notifications, contact information and lead-pipeline management.
- Zillow Premier Agent provides lead management, contact organization, tasks and follow-up tools for Zillow and Trulia leads.
- Your local MLS app should remain the primary source for local listing data, compliance information and agent-only tools.
Final Recommendation
Start with Zillow if you want one app for buying, renting, affordability estimates, shared searches and tours.
Add Redfin if speed and tour scheduling are priorities. Use Realtor.com to compare map layers, school information, flood risk and other property details before making a decision.
