App maker Pocketbook has backed away from claims Netflix has overtaken Foxtel as the subscription service of choice in Australia, after Foxtel discredited the claims.

Fairfax Media published data from Pocketbook on Monday showing Netflix has notched up a 39 per cent market share of the paid subscription video market in Australia since its March 24 launch, nudging ahead of Foxtel, which slipped to 38 per cent.

However, Pocketbook co-founder Bosco Tan now says the data is "most suitable to be used as a leading indicator for forthcoming trends" rather than an accurate reflection of the current market.

"We have adjusted our claims that Netflix is the leading subscription service today compared to Foxtel upon learning that [Foxtel's] business customers contribute to only 1 per cent of their 2.8 million customer base," Mr Tan wrote on the company's blog.
