The oldest device capable of running Whats App is the Symbian-based Nokia N95 released in March 2007.
In August 2014, Whats App released an update to its Android app, adding support for Android Wear smartwatches.
Whats App was officially made available for PCs through a web client, under the name Whats App Web, in late January 2015 through an announcement made by Koum on his Facebook page: "Our web client is simply an extension of your phone: the web browser mirrors conversations and messages from your mobile device—this means all of your messages still live on your phone".
The Commission alleged that in 2014, when Facebook acquired the messaging app, it "falsely claimed it was technically impossible to automatically combine user information from Facebook and Whats App." However, in the summer of 2016 Whats App had begun sharing user information with its parent company, allowing information such as phone numbers to be used for targeted Facebook advertisements.
Facebook acknowledged the breach, but said the errors in their 2014 filings were "not intentional." Both airlines had previously launched customer services on the Facebook Messenger platform.
On February 24, 2009, he incorporated Whats App Inc. However, because early versions of Whats App often crashed or got stuck at a particular point, Koum felt like giving up and looking for a new job, upon which Acton encouraged him to wait for a "few more months".
In June 2009, Apple launched push notifications, allowing users to be pinged when they were not using an app.
