Don't let the ease of use for this app fool you. You know how emails sometimes come across with the wrong tone or get interpreted differently than what you intended? Using Vocal has made it quick and simple for me to make sure my voice communicates exactly what I wanted to say (and HOW I want it to be heard on the other end). Besides Gmail, I've also created an embed to use for people on my website to respond or send voice notes to me. This is a great app and I would recommend it.
