Cablevision is launching an app for customers to watch television on their iPads at home, the company said over the weekend.

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 move by Long Island-based Cablevision comes two weeks after Time Warner Cable launched its own iPad app in mid-March.

The Time Warner iPad app allows users to watch live programming from 32 networks, so long as they are at home using their Wi-Fi network.

But Time Warner’s app sparked controversy.

After getting “cease and desist” letters last week, the No. 2 cable company in the US said it would no longer carry networks owned by Fox (which, like The Post, is owned by News Corp.), Viacom and Discovery Communication.

TV suppliers insist the cable company needs to pay for new licenses in order for customers to use the iPad app.

Cablevision’s app uses its 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.
