Facebook’s Messenger iOS app has begun to lag behind other big names in the messaging space – namely the app it just bought, WhatsApp. Nonetheless, for the time being Facebook is doing its best to differentiate itself from, or at least compete with, its new acquisition with its latest update to its in-house Messenger. Version 4.0 brings group messages and message forwarding to the platform, letting users add friends to groups, set group photos, and other functions that have become associated with the concept of messaging in the mobile age. It signals that, at least for the time being, WhatsApp and Messenger will remain distinctive entities, with Facebook looking to profit from both apps while getting the best of both worlds.
