What's the best Android app for collaborating on documents with others in real-time?

Google Docs is a comprehensive document editor designed for collaborative work on Android devices. Its primary appeal lies in enabling multiple users to edit the same document simultaneously, with changes updating in real time across all platforms. This functionality is ideal for team projects, academic collaborations, or remote work scenarios where instant feedback and co-authoring are essential. Features like color-coded cursors for each editor, an integrated chat and comment system, and flexible sharing via email or link with permission controls streamline group efforts. Users report that the app combines document creation, messaging, and collaboration into one interface, allowing them to 'chat with others, write essays, and collaborate on a project all at the same time.' The inclusion of media embedding for photos, videos, and links further supports creative and practical document development directly from a smartphone. For real-world use, such as coordinating event plans or drafting business reports, Google Docs offers reliable cross-device synchronization and cloud backup, ensuring accessibility without constant internet connectivity. However, some limitations exist, including less precise font size adjustments on mobile compared to the desktop version and the absence of a dictation mode in offline settings, which users with accessibility needs have noted. Additionally, version history viewing is more limited on Android. Despite these minor imperfections, the app remains a strong choice for real-time collaboration due to its no-cost availability, intuitive design, and consistent performance.
