NetSpot alternative for iPhone: WiFi Heatmap & Coverage Map compared
By Rupangkan KalitaPublished
WiFi Heatmap & Coverage Map is a NetSpot alternative for LiDAR iPhones (iPhone 12 Pro and later) and LiDAR iPads. You walk your home once, it draws the rooms in 3D and colours them green where WiFi works and red where it dies, then shows where a booster would go. NetSpot suits any iPhone with an imported floor plan.
If you want a NetSpot alternative on iPhone, the main question is how the map gets made. NetSpot builds its heatmap on a floor plan you import. WiFi Heatmap & Coverage Map draws the floor plan for you with the iPhone's LiDAR scanner while you walk, then paints your WiFi across every room.
How do the two apps make a WiFi heatmap?
NetSpot WiFi Analyzer asks you to import a map of the space, set the scale, and take readings at points as you move around. The heatmap is drawn on that map from your readings.
WiFi Heatmap & Coverage Map starts with the room itself. Point your iPhone at the walls and walk through; the floor plan builds as you go. The app measures as you walk, and the signal appears on the floor you just captured. About ten minutes covers a typical home.
How do they compare side by side?
| WiFi Heatmap & Coverage Map | NetSpot WiFi Analyzer | |
|---|---|---|
| Floor plan | Drawn by LiDAR as you walk | You import one and set the scale |
| Devices | iPhone 12 Pro and later, LiDAR iPads (iOS 17+) | iPhone and iPad (iOS 15.5+) |
| Measured at each spot | Round-trip time to your router, jitter, packet loss, throughput | Speed, ping and low-signal areas on the heatmap |
| View | Your rooms in 3D with the signal on the floor | Heatmap on your imported map |
| Fix suggestion | Marks the dead spot and where a booster would go, with how much dead space it would rescue | Heatmap for you to read |
| Extras | Report to hand to a landlord or provider | Internet speed test, device discovery on your network |
| Account | None; scans stay on your device | Not stated on its listing |
| Price (US, Nov 2, 2026) | Free download; Yearly $19.99 or Lifetime $29.99 | Free download; Plus $6.99, Monthly $8.99, Lifetime $29.99 |
| Last App Store update | 3.3.0, October 31, 2026 | 3.1.6, September 27, 2025 |
What about signal strength in dBm?
Neither app can read your WiFi signal level on iPhone, because iOS does not offer that to third-party apps. Any iPhone app showing a decibel figure is estimating it. WiFi Heatmap measures four things it can genuinely record at each spot instead: how fast your router answers, how steady that is, how many packets go missing, and the throughput you actually get.
Apple's AirPort Utility is the exception: its Wi-Fi scanner can show signal readings because it is Apple's own app. It shows numbers, not a map of your home.
When is NetSpot the better choice?
- Your iPhone has no LiDAR scanner (non-Pro models).
- You are surveying an office or a building and already have a floor plan.
- You also want a list of the devices on your network.
When is WiFi Heatmap the better choice?
- You want to find the dead zone at home without drawing or importing anything.
- You want to see it in your own rooms, in 3D, and point at the spot.
- You want to know where a booster or mesh node would help before you buy one.
- You do not want an account, and you want the scan of your home to stay on your phone.
How do I try it?
Download WiFi Heatmap & Coverage Map from the App Store, open it in the room with your router, and walk through the rest of the home. When you finish, the red patches are your dead zones, and the app shows where a booster would rescue the most of them. The step-by-step version is in how to make a WiFi heatmap on iPhone.
Questions
Is there a NetSpot alternative for iPhone that does not need a floor plan?+
Yes. WiFi Heatmap & Coverage Map draws the floor plan itself with the iPhone's LiDAR scanner while you walk, so there is no image to import and no distance to calibrate. It needs a LiDAR iPhone (iPhone 12 Pro and later) or a LiDAR iPad.
Does NetSpot work on iPhone?+
Yes. NetSpot WiFi Analyzer is on the App Store for iPhone and iPad (iOS 15.5 or later). You import a map of your space and take readings at points as you move, and it builds a heatmap from them.
Can any iPhone app show WiFi signal strength in dBm?+
Not with a public API. iOS does not give third-party apps the WiFi signal level, so an app showing a dBm figure is estimating it. Apple's own AirPort Utility can show signal readings through its Wi-Fi scanner, because it is Apple's app.
What does WiFi Heatmap measure instead of dBm?+
At each spot you stand it records round-trip time to your own router, how much that time varies (jitter), packet loss, and real throughput. Those four decide whether a video call holds up in that room.
Is WiFi Heatmap cheaper than NetSpot?+
Both are free to download with in-app purchases. On the US App Store on November 2, 2026, WiFi Heatmap offered Yearly at $19.99 or Lifetime at $29.99; NetSpot listed NetSpot Plus at $6.99, Monthly at $8.99 and Lifetime at $29.99. Prices vary by country.
Does WiFi Heatmap upload my floor plan?+
No. There is no account, and every scan and reading stays on your iPhone or iPad.
Which one should I pick for an office survey?+
For a multi-floor office with a floor plan you already have, or an iPhone without LiDAR, NetSpot's map-import workflow fits better. For a home where you want to walk once and see the dead zone, WiFi Heatmap is quicker.
