Apple's upcoming iOS 27, which will be unveiled in a few months, is rumoured to add a new Siri app that could quickly become one of Apple's most popular iPhone apps. The Siri app will display prior conversations in either a list or a grid of rounded rectangles with text previews, and includes a toggle for switching in and out of voice mode and an option to upload attachments for analysis. The main interface resembles a thread in Apple’s Messages app with chat bubbles and a text entry field. The new Siri will also offer suggested prompts based on prior usage and adapts to light and dark modes. The app is expected to be a major hit due to its familiarity with Apple's design and integration with other iOS apps.
