Faster WiFi where you actually need it. Walk, tap, and see your dead zones on a colour map — no extra hardware, no subscription, no account.
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.
I found this app by accident after trying 3 other apps that claimed to do heatmaps. This is the only one that actually helped me to create a heatmap of my house WiFi coverage and figure out where the interference was coming from. The instructions are a little hard to follow, but basically after you load some sort of plan of your building (I used a satellite view of my house) you pick points and test the WiFi there. Once you’ve got the point tested you save it and continue until you’ve tested as many points as you need to get a good picture of where the WiFi problems are.
Developer Response
Hello Roachbone, Many thanks for this report, I'm glad you like the app!!! Sincerely, Alexandre Fenyo
Great Tool!

This is a great tool and developer provides excellent support. This is a special tool though for network / Wi-Fi engineers. You need to know how networks work. You need to understand other networking tools and data flow. If you fit these requirements then you can understand how this app will be of use to you. This app provides very good throughput mapping but does not provide power levels from AP. However, this appears to be able to replace a walkthrough assessment using iPerf. It is one of several tools needed when assessing Wi-Fi. It doesn’t do it all but what it does do it dies well.
Crashes in iOS 17.2
3rrat1c
After updating to 17.2, the app crashes moments after opening. Prior to that, the app seemed to work well, gathering information for devices on your network. As of right now, 1/3/2024, I am unable to use the app.
Developer Response
Hello, this launch crash was fixed in version 3.6 (April 2024) and the app has been stable since. Update the app and it will start normally. Sorry for the trouble, and thanks for the report.
