Develop a live voice chat app for Windows, Macs, iOS and Android devices

Live voice chat apps are increasingly popular, especially in gamer communities. However, most of these apps are only available on PCs. Here is an idea to develop a live voice chat app for PCs (Windows and Macs), iOS and Android devices. <br><br>This app should have the following features:<br><br>* live voice chat;<br>* voice message recording and sharing;<br>* text messaging;<br>* emojis and sticker usage;<br>* file sharing;<br>* creation of chat groups.<br><br>Target users can be people with shared interests, friends and family, and colleagues. The app can be monetized through in-app purchases of virtual gifts, premium features, and targeted advertisements.
