What's the best iOS app for creating and editing presentations on my iPhone?

Microsoft PowerPoint is the definitive choice for building and modifying presentations on an iOS device. The app successfully translates the core functionality of its desktop counterpart to a mobile interface, allowing users to create slides from scratch, apply sophisticated formatting, and insert charts or media. A key strength is its seamless integration with cloud services like OneDrive and SharePoint, ensuring work automatically saves and syncs across all devices. This is particularly valuable for professionals who need to make last-minute edits while away from their computer. The inclusion of the Copilot assistant can help generate slide content or design ideas, speeding up the initial drafting process. Real-time co-authoring is another standout feature, enabling multiple team members to work on the same deck simultaneously during a remote planning session. While the interface is generally intuitive, some advanced formatting options can feel slightly cramped on the smaller iPhone screen compared to an iPad or desktop. Overall, the app provides a robust, reliable mobile solution for serious presentation work.
