WhatsApp co-founder Brian Acton said just four days ago that voice calling is coming to WhatsApp for iOS in "several weeks." As of Tuesday, however, Android users can begin placing voice calls to their WhatsApp contacts.

VentureBeat discovered that the feature was quietly launched inside of version 2.12.19 of WhatsApp, which is directly available from the company's website but doesn't appear to have populated inside of Google Play just yet. The calling function is embedded in the app next to the contacts and chats tab, VentureBeat said. The news outlet warns that the feature isn't fully baked, and described call quality as "awful," which explains why WhatsApp probably isn't advertising the function just yet.

We hope WhatsApp cleans up the calling function for the sake of end users. If you're willing to live with the chance of poor voice quality and want to hear from your grandma abroad, head to WhatsApp's site and check out the new app.
