In an era where internet is everything, living without it for few hours can really be hard. Most devices you carry like a laptop or a smartphone are useless without connecting to the web even for general works. While this won't be a problem when you're at home, stepping out without a personal mobile hotspot makes it hard. Thus, here's a service that lets you find free WiFi hotspots wherever you go - WiFi Warden.
By nature, WiFi Warden is a locator of WiFi hotspots around you, that are shared by others. Allowing location access when setup will let WiFi Warden search for available internet hotspots nearby your location, so that you can connect to any of them.
This makes you rely less on cellular data, and save that for future. You can filter for available WiFi spots by places, analyze and can connect to them through WPS. Also, you can see who's connected to your WiFi network and can restrict or block them. With WiFi Warden, you can see all the technical information a WiFi (router) carries, like the IPv6 address, router brand etc
You can create a WPS PIN for your supported router and check open ports of a device on the network. Apart from that, you can view saved passwords of a WiFi network and even set strong passwords suggested by WiFi Warden, that are hard to guess thus un-hackable.
After all, WiFi Warden is not a hacking tool if you're suspecting. The initial look-up for available WiFi hotspots around you needs internet connection (minimal), and once connected to a specific WiFi, you can turn off the primary internet connection. While WiFi Warden can surface most hotspot areas, don't panic if cannot find one.
This could be since there are no available WiFi hotspots around you. But with ever increasing network of WiFi Warden, you are most likely to find one wherever you go. All its features are free, since it earns through ads. And a paid version of WiFi Warden removes the ads.
Also to note, you may require your device to be rooted for using some special features like viewing saved WiFi passwords, connecting to a WiFi through WPS, to see the serial number of an access point etc.
