This free app is a simpler version of Office 365

LibreOffice is a free and open-source alternative to Microsoft 365 and includes similar apps and features. It’s compatible with Word, Excel, and PowerPoint formats, so everyone can access your files. LibreOffice also works on most systems, including Windows, macOS, and Linux. Mobile apps are available for iOS and Android phones, but these are primarily for viewing documents and spreadsheets and have limited editing features.
