Facebook-owned chat messenger WhatsApp launched a web client earlier this year, but the QR code you need to scan to access it didn't work for iOS devices. If you felt left out that time, update your app and check for "WhatsApp Web" in the Settings section, because the web client is now available for iOS users. Just go to web.whatsapp.com -- you can now see the iPhone listed among its supported devices -- and access "WhatsApp Web" on your iOS app's Settings to scan the QR code that appears on your computer. Once that's done, your conversations will sync, and you can start chatting on the web. Note, however, that the web client is just an extension of the mobile app, so it won't work if your iPhone's not connected to the internet.
