Emotions can be hard to put into words, let alone communicate. A new iOS app called Cove tries to make this process easier by letting you make a diary of music that can speak where speech fails. The app helps you make music that shows how you feel, whether it’s happy, sad or anywhere in between. After making these mood pieces, you can share them with important friends or family, which can help them understand your confusing feelings. Built by a company called Humane Engineering, Cove isn’t the first and won’t be the last time that businesses try and use sound to get around your problems.
