WiFi CreekLink Pro answers the three questions people actually ask about a network: how fast is it, how strong is it, and is it safe? It's a small network-detection tool that inspects the wireless networks around you and reports back in plain numbers.

The speed test covers the standard trio — ping, download and upload for your current connection — enough to check whether you're getting roughly what you pay for, or whether the café connection is as tired as it feels. Signal strength readings do the quieter work: walk the apartment with it and the dead zones announce themselves.

Security gets a look, too. For surrounding networks the app reports channel information and encryption type, which is the difference between joining an open network blindly and knowing it's open before your banking app ever opens. Channel data also hints at congestion — too many neighbors shouting on the same channel is a classic cause of mysterious evening slowdowns.

The neatest extra is a floating monitor: a small overlay showing real-time traffic statistics while you use the phone normally, so a suspicious upload spike or a stalled download is visible the moment it happens. It's a brand-new, tiny app (1K+ downloads; its 5.0 rating rests on very few reviews), but the toolkit it describes is the right one for quick network answers.
