Android only: Many places offer “Free Wi-Fi!” They also require you to enter a username/password combo, or simply click “I Agree,” in a browser. Free app Wifi Browser Login can automatically notify you, or open a browser, when that’s the case.
Once you install the app, the only thing you’ll need to do is open it up and check off your preferred settings. You can have a notification window pop up when you need to launch a browser for full web access, or just have your browser launch automatically. It’s a feature you’d hope would make it into a future version of Android itself, but for the meantime, this app does the job neatly at Starbucks, your library, or anywhere else with a login-required connection.
