## What is WiFi Heat Map & Analyzer?

Find your home WiFi dead zones in under 10 minutes, using nothing but your iPhone.
Walk from room to room, tap to measure, and watch a color map of your actual WiFi
performance build itself — speed and latency, where you really live.
No subscription. No ads. No account. One purchase, yours forever.

WHAT YOU CAN ACTUALLY FIND OUT
- Which rooms are slow, and how slow, in numbers you can act on
- Whether the problem is your WiFi or your internet connection
- Where to put a mesh node, an extender or the router itself
- Which of the devices on your network is eating your bandwidth
- What every IoT device on your network is broadcasting about itself

HOW IT WORKS
1. Pick one of the ready-made floor plans, or use a photo of your own plan
2. Walk to a spot, tap once — the app measures throughput and latency there
3. Repeat for each room. The heat map builds as you go
4. Save the finished map to your photos, to compare after you move the router

Step-by-step mode does the setup for you: no target to choose, no protocol to
configure, no documentation to read. The advanced interface is still there when
you want full control.

NO EXTRA HARDWARE. NO SUBSCRIPTION.
Professional WiFi surveys need an Ekahau Sidekick or a WLAN Pi. This app needs
your iPhone. And unlike almost every other WiFi analyzer on the App Store, there
is no weekly plan, no annual plan, and no ads — you buy it once.

ALSO A COMPLETE NETWORK TOOLKIT
- Scan every device on your LAN, with vendor, IP address and open ports
- Discover every mDNS/Bonjour service: HomePod, Apple TV, printers, IoT
- Ping and latency to local devices and to any internet host
- Throughput measurement against another device running this app, any TCP
  CHARGEN/DISCARD server, or the internet
- Run a TCP CHARGEN or DISCARD service on your own device
- 3D animated view of your local network topology

FULL SNMP CLIENT INCLUDED
Query any SNMP agent on your routers, switches, access points and printers.
SNMP v1, v2c and v3, with noAuthNoPriv, authNoPriv and authPriv, MD5 and SHA1
authentication, DES and AES privacy. 64 standard MIBs are bundled, so object
identifiers are resolved to readable names offline — no server, no subscription,
nothing to configure beyond the agent address and credentials.

FOR HOMES AND FOR PROFESSIONALS
Built by a network engineer. Simple enough to diagnose your apartment on a Sunday
afternoon, precise enough that telecom professionals use it on the job.

BEFORE YOU BUY — WHAT THIS APP DOES NOT DO
Apple does not let any third-party iOS app read WiFi signal strength or scan
neighboring networks, and no App Store app can do it — this is why professional
tools need external hardware. This app maps what it can measure at the spot where
you are standing: real throughput and latency. That is what a home heat map needs.
It measures the network you are connected to, one heat map at a time.

## Key features

- 3D animated network view
- Network analyzer tools
- Wireless network heatmap
- Device discovery
- Open TCP port scanning
- mDNS/Bonjour service discovery
- Latency and throughput measurement

### 3/5 — Fast Update but doesn’t read rssi

*2026-09-24*

Nice tool thanks. But the heatmap read traffic speed and not WiFi rssi .

**Developer response:** Thank you for reporting this, and sorry for the inconvenience. iOS 27 changed the way apps are required to start up, which made the app close immediately after launch. This is fixed in version 6.3, now available on the App Store: please update the app and it will start normally on iOS 27. If you still run into any problem, please contact us through the support link on the App Store page.

### 1/5 — Not useable iOS 27

*2026-09-21*

App starts and close instantly on iPhone 18 iOS 27.

**Developer response:** Thank you for reporting this, and sorry for the inconvenience. iOS 27 changed the way apps are required to start up, which made the app close immediately after launch.

### 2/5 — clunky workflow

*2025-11-08*

inexpensive and no subscription, but I was hoping to wander around in my flat and create a heat map of my wifi / wlan … 

instead you have draw / upload your floor plan yourself and pin the measurements manually - technically it is working, but the experience is cumbersome

**Developer response:** Hi Herr, thanks for you review. If you do not want to upload your floor plan and also want a semi-automatic way to take the measurements, you may choose « step-by-step » at the start screen, instead of « advanced interface ». You will be able to choose one of the four predefined simple floor plan examples, and take each measurement with only one click.

### 4/5 — Bien fait mais teste le débit plus que l’intensité du réseau

*2025-01-30*

L’application n’est pas très intuitive lorsqu’on l’ouvre la première fois, mais en suivant les guides indiqués on arrive à faire ce qu’on veut. Attention toutefois, cette application ne mesure pas l’intensité de réception du réseau Wifi. Elle fait plutôt des mesures de débit. L’application doit donc être installée sur deux appareils, dont l’un doit être connecté soit en filaire au réseau local soit en Wifi à proximité immédiate d’un routeur Wifi du réseau local. L’autre appareil est alors emmené dans tous les endroits du lieu à tester, et des données sont échangées entre les 2 appareils. Le débit constaté à chaque point de mesure permet alors d’établir la heatmap. Il est possible de n’avoir qu’un seul appareil, dans ce cas l’échange de données se fait entre l’appareil et un serveur sur Internet (ce qui est peu optimal car la mesure est alors dépendante du trafic Internet). L’application fonctionne bien, mais l’inconvénient c’est qu’une mesure faite à un point donné ne sera pas toujours la même en fonction de la charge du réseau, alors que l’intensité du Wifi reste théoriquement la même pour un même point géographique. Il faut donc bien savoir que l’application mesure un débit (dont la vitesse peut varier en fonction de l’occupation du réseau) et pas l’intensité du Wifi elle-même. C’est une chose à savoir pour faire un choix éclairé. Ceci dit, elle fait très bien le job. Des progrès pourraient être faits sur l’ergonomie et l’utilisabilité, mais ce n’est pas non plus une application pour le grand public donc ce n’est pas grave.

### 1/5 — Doesn’t work

*2024-10-14*

The app opens for a split second and then crashes - good one

**Developer response:** This has been fixed, it now works correctly on iOS18. Many thanks for the bug report.

### 1/5 — Crashes on launch. Please fix!

*2024-10-09*

The app crashed when I launched it. Looking forward to the mapping functionality once fixed.

**Developer response:** This has been fixed, it now works correctly on iOS18. Many thanks for the bug report.

### 1/5 — Ne fonctionne pas

*2024-10-02*

Des la mise en route l’apps big et se ferme (ios 18.0) donc totalement inutile.

**Developer response:** Désolé, c'est dorénavant corrigé, l'app fonctionne désormais correctement sur iOS 18, merci pour votre signalement. Voici ce qu'il s'est passé : un symbole Objective-C utilisé par WifiMapExplorer a été rajouté par Apple avec le même nom dans une bibliothèque de base d'iOS 18 (le symbole était nommé "Trace"), ce qui fait que l'éditeur de liens dynamique était confronté à deux symboles avec le même nom, et il arrêtait donc le lancement du programme. J'ai donc mis à jour le nom du symbole, l'application se lance désormais correctement sur iOS 18. J'ai profité de la mise à disposition de cette nouvelle version de WifiMapExplorer pour rajouter quelques modifications mineures (page d'accueil avec accès direct à la documentation et quelques améliorations concernant les performances).

### 1/5 — Does not even start

*2024-09-29*

Crashes right away.  Don’t bother.

**Developer response:** This has been fixed, it now works correctly on iOS18. Many thanks for the bug report.

### 1/5 — Crashes r us

*2024-09-26*

Just bought this app and it opens and then crashes. It does not work on iPad iPhone and MacBook. Waste of money.

**Developer response:** This has been fixed, it now works correctly on iOS18. Many thanks for the bug report.

### 1/5 — Fails to open

*2024-09-24*

Perhaps not ready for newest iOS, flashes menu then dies.

**Developer response:** This has been fixed, it now works correctly on iOS18. Many thanks for the bug report.
