WiFiman Alternatives: 5 Wi-Fi Analyzer Apps Compared (2026)

WiFiman from Ubiquiti is a solid free Wi-Fi tool, and for a lot of people it is all they need. But these apps are not really competitors: they answer different questions. Picking the right one starts with knowing which question you are actually asking.

We make one of the apps below, so read our entry with that in mind. We have tried to be straight about what it does not do.

At a glance

First, the thing that affects every app on iPhone

Apple does not allow apps to scan nearby Wi-Fi networks or read signal strength. This is a platform rule, not a gap in any one app, and it means channel graphs and dBm readings are an Android feature no matter whose app you install. Anyone promising otherwise on iPhone is measuring something else. We wrote about the detail in why your iPhone will not show Wi-Fi signal strength.

If you are on iPhone, the realistic options are speed and response-time tools, device discovery, and your router's own app.

WiFiman

Ubiquiti's free app includes a speed test, a live signal view that tracks signal strength, latency and roaming as you move, network discovery and detailed connection information (Ubiquiti's WiFiman guide). Its extra features shine if you own UniFi equipment.

Good fit if: you have Ubiquiti gear, or you are comfortable reading dBm figures and channel numbers and want the raw view.

Less good if: you want to be told what the numbers mean rather than shown them.

Wifify

Wifify is built for people who want an answer rather than a spreadsheet. Its Network Doctor checks your phone, Wi-Fi, router, provider and websites in order and says which one is the problem, in a sentence, with the fixes for that cause. It also includes:

• A speed test that explains what your speed is good for and compares every result with the plan you pay for, plus a report you can send your provider
• A live signal meter with router and internet response times
• Device recognition by the names devices announce, with new-device alerts
• Channel advice that ignores your own router's extra networks
• A safety check that reads the encryption in use and looks for risky settings on your router
• Room Check, which estimates Wi-Fi levels at a bed or cot against the international safety limit

Good fit if: you want plain words and a clear next step.

Less good if: you want professional site surveys or a floor-plan heatmap, which we do not do; or you are on iPhone, where the platform limits above apply and some features are unavailable.

Fing

Fing is best known for device discovery. It identifies devices using several network protocols, including Bonjour, UPnP, SNMP and NetBIOS, and includes tools such as ping, traceroute and port scanning (Fing). Some features, such as ongoing network monitoring and alerts, belong to its paid plans and its own hardware.

Good fit if: your main question is "what is every device on my network?"

Less good if: you want Wi-Fi radio diagnosis rather than an inventory.

Speedtest by Ookla

The most familiar name in speed testing, with a very large server network and a history of your results. It is focused on measuring your connection to the internet rather than diagnosing what is happening inside your home.

Good fit if: you only need a quick, widely recognised speed number, or one a provider will accept as a reference.

Less good if: your speed is fine and your Wi-Fi still feels bad, which is the most common situation of all. See ping, jitter and packet loss for why.

WiFiAnalyzer (open source)

A free, open-source Android app with detailed channel graphs and signal-strength charts for nearby networks. It is excellent for channel planning if you are comfortable reading graphs, and it has no account and no ads.

Good fit if: you want raw channel data and nothing else.

Less good if: graphs are not how you want to be told things.

NetSpot

NetSpot focuses on Wi-Fi site surveys: you walk a floor plan and it builds a coverage heatmap. It is aimed at people planning or troubleshooting larger homes and offices, and the serious features are paid.

Good fit if: you need a proper coverage map for a big space.

Less good if: you have one weak room and just want to know why.

Which should you choose?

• "Why is my Wi-Fi slow?" Start with Wifify's Network Doctor, or work through why Wi-Fi gets slow.
• "Who is on my network?" Fing or Wifify.
• "Which channel should I use?" WiFiAnalyzer or Wifify. See finding the best channel.
• "I need a heatmap of the whole office." NetSpot.
• "I run UniFi." WiFiman.
• "I just want a number right now." Our free speed test runs in the browser with no app at all.

Feature lists change often, so check each app's store page for the latest details before you decide.
