Flyer is a social media app. The user will be able to sign up to create an account. With this account, he/she will be able to add their friends, by searching for an existing username. Here they can freely send each other voice messages through the application. The voice messages can be sent to one friend, or to a group of friends, by sending to a group which the user has created. The voice message can only be recorded for a maximum of 12 seconds - and it can ONLY be opened ONCE. The user can choose to hear the voice-message before he/she sends it to their friends.
