Customer Reviews

Good looking app with super functionality

I’ve been using WiFi Explorer for over a year now, and it has proven to be extremely useful. It allows me to walk around a customer site, find dark spots in WiFi coverage, determine locations where channels density is low, and generally provide me with insight into the coverage of the wireless network.

I also appreciate the help files which the app offers, because they help me understand the meanings of some obscure terms and measurements, like dbm.

I highly recommend this app!

The best at what it does

I love this app. It’s so slick and easy. I run in once weekly to see what new wi-fi networks have popped up near to my home. Then I adjust the channcels of my own to reduce intereference. Becuase of this I get great sustained and reliable throughput everywhere in my 2-story house, even with a repeater. Still the best.

Awesome App, Solid updates

This app is amazing. Powerful data collection tool. Powerful troubleshooting tool. Easy use. This latest update includes all fields in the CSV export, which is the only ask I had previously. Pretty stoked about that. Hats off to the dev, solid work here.
