Open Source Kotlin Task Managers

Flux is an Android productivity application that combines notes, tasks, journals, habits, and events in customizable workspaces. It allows users to create dedicated spaces for different projects, routines, and personal activities. Flexible templates help organize information according to individual workflows. Its Markdown editor supports formatted text, code blocks, tables, mathematical expressions, and Mermaid diagrams. Task management includes recurring activities, reminders, progress tracking, and completion statistics. Daily journals provide space for reflections and longer written entries. An integrated calendar organizes events and important dates, while habit analytics visualize progress over time. Media attachments enrich notes with images. Built with Kotlin and Jetpack Compose, Flux uses local storage, optional biometric protection, and Material 3 customization.
