Nothing collaborates with Sunbird to create the exclusive app "Nothing Chats" for Phone 2, allowing Android users to send iMessage-compatible blue-bubble messages on iOS devices. The app offers features like group messaging, read and delivery receipts, live typing indicators, and high-res media, with Sunbird's patented process using Apple devices as waypoints for iMessages. Nothing Chats claims encryption and privacy, but skepticism remains about the app's seamless experience and Apple's potential response to such solutions.
