Using the Vidtalk app is easy and straightforward. To get started, simply download the app from your device's App Store or Google Play store. Once you have downloaded it, open up the app and sign in with either an existing account or create a new one using your email address. After signing in, you will be taken to a main page where all of your contacts are listed so that you can easily start video calls with them by tapping on their name/picture. You also have access to other features such as creating group chats for multiple people at once and sending messages directly within the chat window itself if needed during conversations! Additionally, there are plenty of customization options available which allow users to personalize their experience even further - this includes changing background images/colors as well as sound effects when someone enters or leaves a call! All-in-all, Vidtalk makes connecting with friends & family over video simple & enjoyable - giving everyone more opportunities than ever before to stay connected no matter how far apart they may be geographically speaking!
