One of those alternatives is a new browser called iLunascape from Lunascape, Inc. and it is available for free (iTunes link) in the iTunes App Store.
This browser takes a new approach to browser user interfaces (UI) on the iPad and I’m wondering why no one else has thought of this yet. The developer’s new specialized UI called the “In Reach Interface” has clustered most common movements and tabs down near the bottom of the iPad display where the user generally holds the device. In addition to this the iPad user experience is the center of attention, but now includes desktop-class tab browsing, easy screen capture and storage, fast and smooth scrolling, simple bookmarking, and iPad rotation controls.
iLunascape may not be for everyone, since not everyone holds their iPad the same way. However, if you are looking to replace Safari this app is a good start with its unique interface and useful desktop like features. Its free and if you care about your browsing experience on the iPad — go get it.
