FEATURES: • Prioritization: label tasks important, urgent, both, or neither so your priorities are always clear • Quick Planner: surface tasks that are overdue, due soon, or left behind • Markdown notes and a customizable journal with reflection prompts • Calendars in one place: your device calendars, or .ics feeds on the web • Habit tracker, goals, and milestones • Repeating tasks and native task alarms so nothing slips • Connect to AI: an MCP server lets Claude, ChatGPT, Gemini, and Cursor plan alongside you • Customizable themes, on iPhone, iPad, and the web Dexter is open source under the MIT license: https://github.com/cvburgess/dexter
