Facebook launched a new app called HELLO for Android, which acts as a dialer as well as a caller ID app, letting users know who is calling even if they do not have the number saved on their handsets. It is an app built by the team behind the Messenger app.


The app is essentially a dialer for Android, allowing user to block numbers and see who is calling them, even if they don't have  the number saved in their phone.

Hello connects with Facebook so you can see who's calling, block unwanted calls and search for people and places.

Facebook Hello syncs with the users would only see the number and name of callers only if the callers have chosen to share those details publicly. If they have only chosen to share the number with friends, only others in their friend list will see the number through the Hello app.


If you're worried about privacy, Hello makes it easy to block unwanted calls. From your settings, you can block specific numbers and adjust whether you want to automatically blocks calls from commonly blocked numbers.

Caller must have also have a Facebook account in order for the data to be shared but they don't necessarily have to be logged in at the time of the call. They also don't need  to have Hello installed, either.

An important part of the app is that it can easily be installed on any android phone, so for those who regularly change phones or have multiple phones for different purpose, family and friends will still know who the user is when they call.

The Facebook Hello app, though still in testing, is listed on Google Play, but is not available to download outside of the US, Brazil and Nigeria.
