The service, available at no extra charge, will allow the cable operator's more than 3 million customers to watch some 300 channels, search programming by genre and enable customers to record programs.
The system uses Cablevision's digital cable television network to deliver programming to the iPad, so customers do not need to have Internet access on their devices to use the app.
"This application allows the iPad to function as a television, delivering the full richness and diversity of our cable television service to a display device in the home," Tom Rutledge, Cablevision chief operating officer, said in a statement.
The move by New York-based Cablevision comes weeks after Time Warner Cable launched its own iPad app in mid-March.
The Time Warner version allows users to watch live programming from 32 networks so long as they are at home using their Wi-Fi network.
