If you need to check property lines, the right app depends on whether you want official parcel data (owner records, deed lines pulled from county sources) or a simple way to mark boundaries yourself. LandGlide and Regrid both pull real parcel data from county records — Regrid's owner lookup is actually free with no time limit, while LandGlide's free trial only lasts 7 days. Mapulator, GPS Fields Area Measure, and Google Earth are free tools for marking boundaries manually, but none of them access official ownership records. Here's how the five compare.
Property line apps compared
| App | Platform | Free Version | Ad-Free | Offline Mode | Cost After Trial |
|---|---|---|---|---|---|
| LandGlide | Android, iOS | 7-day trial | Yes | Yes | $9.99/mo or $99.99/yr |
| Regrid Property App | Android, iOS | Limited, free tier | Yes | No (needs ArcGIS Pro) | $10/mo or $100/yr |
| Mapulator | Android, iOS, Web | Yes, fully free | Yes | No | $0.58/mo or $6.99/yr (optional) |
| GPS Fields Area Measure | Android, iOS | Yes, with ads | No | No | $1.39/mo or $16.77/yr |
| Google Earth | Android, iOS, Desktop | Yes, fully free | Yes | Limited | Free |
A quick note on "free" here, since it matters: Mapulator, GPS Fields Area Measure, and Google Earth are free to use ongoing. Regrid's free Starter tier is also genuinely useful — it includes owner name and mailing address lookups, not just boundaries — but its measurement and export tools sit behind the $10/month plan. LandGlide's full feature set, including ownership data, is only free for the first 7 days.
Looking for a free LandGlide alternative specifically?
LandGlide's parcel data (owner names, deed records) is genuinely useful, but $9.99/month adds up if you only need it occasionally. Regrid's free Starter tier is actually the closest match — it includes owner name and mailing address lookups at no cost, nationwide, with no time limit. The tradeoff is that Regrid's free tier doesn't include its measurement or export tools, and its interface leans more toward property research than field measurement. If you specifically need boundary measurement, not just ownership lookup, for free, Mapulator or GPS Fields Area Measure are better fits — they let you manually mark and measure the boundary yourself from satellite imagery, though without official ownership records attached.
The 5 best property line apps, in depth
1. LandGlide
LandGlide shows property data and parcel boundary lines, using your GPS location to identify what property you're viewing. It details ownership, sale price and date, square footage, and address — real county-sourced data, not manually drawn.
Pros:
- Real parcel/ownership data
- Address-based search
- Offline maps once downloaded
Cons:
- Free trial is only 7 days
- Requires an account login
- Offline maps must be downloaded in advance
2. Regrid Property App
Regrid provides property insights and location intelligence across the US. The free Starter tier lets you view ownership details — owner name, mailing address — alongside property boundaries, at no cost and with no time limit. A paid subscription adds measurement tools, data import/export, and team collaboration.
Pros:
- Free tier includes real ownership and mailing address data, not just boundaries
- Paid subscription adds measurement and import/export tools
- Offers team collaboration
- Includes a floodplain layer to check flood risk
Cons:
- Measurement and export features are paywalled
- Offline access requires a separate ArcGIS Pro workflow, a real barrier for casual use
3. Mapulator
Mapulator uses GPS to help you measure areas, distances, and boundaries directly on satellite maps — free, with no ads, on Android, iOS, and in the browser.
Pros:
- Fully free, no premium paywall on core features
- No ads
- Measures area, distance, and perimeter with multiple layers and custom units
- Import/export via KML/GeoJSON, shareable by link
Cons:
- No official parcel/ownership data — boundaries are drawn manually
- No offline maps
- Free tier saves only two projects
4. GPS Fields Area Measure
Built originally for farmers measuring field perimeters, this app supports both manual and GPS-based measurement and works without creating an account.
Pros:
- No login required
- Measures area, distance, and perimeter
- Paid version supports external GPS devices for higher accuracy
Cons:
- Free version has frequent full-screen ads
- Premium tools are paywalled
- Requires an internet connection
5. Google Earth
Google Earth offers detailed 3D satellite imagery worldwide, with built-in distance and area measurement tools — genuinely useful, though most people default to Google Maps instead and don't realize Earth has this capability.
Pros:
- Free
- Detailed, frequently updated imagery
- Measures both distance and area (Google Maps only measures distance)
- Historical imagery lets you compare a property over time
Cons:
- Large app size
- Requires a strong connection for full functionality
- Limited offline capability
Which is the best property line app for you?
- Need real ownership/deed records for a transaction or dispute? LandGlide is built for exactly that — worth the subscription for the specific job.
- Want the most accurate boundary data available? LandGlide and Regrid both pull from official county parcel records, which is inherently more accurate than a manually drawn line — Mapulator and GPS Fields Area Measure are accurate for the measurement itself, but the boundary you draw is only as accurate as where you place it.
- Just need to mark and measure a boundary yourself, for free? Mapulator or GPS Fields Area Measure both work; Mapulator has no ads, GPS Fields doesn't require an account.
- Want to see historical changes to a property over time? Google Earth's historical imagery is the only option here that does this.
- Managing multiple properties for a team or business? Regrid's collaboration features are built for that specifically. None of these — including LandGlide — are a substitute for a licensed survey when boundaries matter legally (a property dispute, a new fence line, a sale). Use them for planning and personal reference; hire a surveyor when the result needs to hold up officially.
FAQ about Property Line Apps
Is there a free alternative to LandGlide?
Regrid's free Starter tier is the closest match — it includes owner name and mailing address lookups nationwide at no cost, though its measurement and export tools require the paid plan. Mapulator and GPS Fields Area Measure are free too, but they don't pull ownership records — they're better suited to manually marking and measuring a boundary yourself.
Can I see who owns a property next to mine for free?
Often yes, through your county assessor's public records website, without needing an app at all. Apps like LandGlide just make that same public data easier to search and view on a map.
Are property line apps accurate enough for building a fence?
For planning purposes, yes. For a legally defensible boundary — especially near a shared property line — get a licensed survey first. A misplaced fence based on app data alone can become an expensive dispute.
