Serengeti simplifies web surfing at WiFi hotspots that need you to log in. It works by logging you in automatically before launching Safari, so you’re ready to surf immediately.

Serengeti uses Devicescape’s Easy Wi-Fi service in order to login, so you need an Easy Wi-Fi account to get started.

After this, Serengeti will work automatically, becoming a one-click-and-surf solution
