Nothing Chats, a new app by smartphone brand Nothing, aims to improve messaging between Android and iPhone users by bypassing the green bubble stigma and enabling more features. While the app has some bugs and usability issues, Apple's announcement of official RCS support next year may render third-party apps like Nothing Chats unnecessary. Connecting with contacts on Nothing Chats can be challenging, and the app has specific requirements for successful messaging, such as linking phone numbers to Apple IDs.
