It’s an app that will help you login to WiFi hotspots, which are found very often in public transportation, or buildings. Universities, healthcare centers, hotels, etc. These examples are called captive portals. Recent phone models, such as the Android 5.x , 6 , and 7 are well supported. Check this link to see the supported WiFi Lists.
A captive portal is a network that requires an HTTP client to see a special web page (usually for authentication purposes) before using the Internet. A captive portal turns a Web browser into an authentication device. These are commonly used on WiFi networks where authentication to the private network is done via a login browser page, rather than the use of a WEP or WPA2 key, which includes some coffee shops and airports, and hotspot providers such as The Cloud and ATT-WiFi.
This app can be purchased from the new address “Google Play Store” (link updated), or search “helloGuestWifi”

Typically, when you connect to WiFi, you will be redirected to the login page, which possibly may have an username/password, or just a checkbox to agree to the terms. Once you actually get the username/password, you might find it irritating that you have to enter it very often. At some locations, you might have to enter it several times a day. The goal of WiFi Web Login is to help you login to any hotspot automatically.
