The company said that ‘app Pins’ will be visible within its iOS app — bad news for Android-loving Pinners, this is an iOS exclusive — and will allow users to pin their favorite apps, and also download apps for an iPad or iPhone without leaving the Pinterest app.
That’s significant not only because the App Store is brimming with apps, more than 1.4 million to be precise, which make finding new downloads tough, but because Pinterest is inherently mobile. The company told The New York Times that 75 percent of activity on its service — which has an estimated 70 million monthly users — comes from mobile devices.
Apple took the lead and opened an ‘App Store’ account on Pinterest to help showcase apps.

The U.S. company has raised significant capital from investors — it closed a $200 million Series F round at a $5 billion valuation in May 2014 — but only recently has moved towards monetizing its service. Promoted pins are an obvious source of revenue, and app Pins — though initially for users — could also yield revenue for the company if it decides to open them up to developer and advertiser promotion.
There’s a case for that move already. Facebook app installs have blossomed into a lucrative business for the world’s most popular social network, while Twitter lets developers promote app download links on its service. Pinterest doesn’t enjoy the same scale as either of those companies, but this new opportunity to gain downloads among its loyal user base could become an interesting acquisition channel for developers.
