Governors Island and Highline are two of New York City’s newest and most popular parks, and there are apps for both of them. That’s handy (pardon the pun) since both parks are growing and changing each season.
The Governors Island app is called, simply, Gov Island, by Janet Garingo. The app for the Highline is included within Greenwich Village Insider, by longtime GV resident Susann Tepperberg, who is a friend and fellow member of the Society of American Travel Writers. Both are available for download from the iTunes store.
Another app I can recommend is my own — NYC Free and Frugal — published by Sutro Media, the leading travel app publisher. And also the app version of my Peaceful Places in NYC guidebook, just released.
