Listen is an app that aims to be your “smart phone number.” What does that actually mean? Well, it’s about giving you more features than a regular phone number. If something comes up in a text conversation that you need to take care of, you can set up a reminder. Or you can save texts to so that they show up directly on a caller profile. You can also hide notifications from anyone except your favorite contacts, and also set up auto responses. And if there’s someone you don’t want to hear from, you can mute them or disable voicemails.
