VideoAndVoice is a free video and voice calling app available for Android users. Developed by NAKAMURA TAKASHI, this app allows users to connect with their friends and family through video and voice calls.

To start using the app, simply launch it and enter the ID of the person you want to connect with. Once you have entered the ID, tap on the call button and you will be connected to the other person. The app is completely free to use, so you can talk for as long as you want without worrying about any charges.

VideoAndVoice is a great app for those who want to stay connected with their loved ones. The app is easy to use and provides good quality video and voice calls.
