Cellular networks being what they are in India, there are plenty of times when you end up stuck on a slow 2G connection, where nothing but WhatsApp works. And lets face it, being offline is something most people would rather avoid. In such a situation you can either go around looking for Wi-Fi networks and try asking people to share Wi-Fi passwords, or try an app like WiFire.
WiFire finds all open Wi-Fi networks around you and helps you navigate to them. The app shows you how far you are from the nearest public Wi-Fi network and even the speed of the network. There are plenty of apps that do the same thing but some are spammy, some are scammy, and many of them dont have a great database of Wi-Fi networks in India. WiFire is not like those apps.
