TaskFlow Studio: Because your to-do list was getting a little too confident. TaskFlow Studio Your tasks, calendar, notes, and daily plan finally agreed to sit at the same table. TaskFlow Studio is a modern productivity app for people who want more than a checklist but less than a second job managing their checklist. Plan your day, organize reminders, review upcoming work, pin important lists, track notes, and see tasks alongside calendar events without bouncing between five apps and a mild existential crisis. Built for iPhone and iPad, TaskFlow Studio gives you flexible views for the way your brain actually works: lists, agenda, calendar, timeline, notes, smart lists, widgets, and a guided Plan My Day view for when “just wing it” has stopped being a strategy. What You Can Do Plan your day with a focused view for overdue, flagged, high-priority, and upcoming tasks. See tasks and calendar events together in Day, Week, Month, and Agenda views. Use widgets to check today’s task count, view due tasks, and complete tasks right from your Home Screen. Add tags, statuses, flags, subtasks, notes, attachments, and locations to tasks. Pin locations and open them in your default maps app when it is time to go places, unfortunately. Search across tasks, notes, comments, tags, attachments, and locations. Use smart lists, pinned lists, filters, sorting, and themes to make the app feel like yours. Open the Command Bar to quickly create tasks, jump views, search, filter, and move around faster. Enjoy a better iPad layout with side-by-side task lists, calendar views, and details. Why TaskFlow Studio? Because productivity apps should help you do the work, not become the work. TaskFlow Studio keeps Reminders and Calendar at the center while adding the planning tools Apple’s built-in apps leave on the table: better task views, richer metadata, CloudKit-backed extras, widgets, notes, smart lists, themes, and a daily planning flow that gently asks, “Are you sure you can do 37 things today?” You cannot. But you can do the right few. Great For Daily planning
Reminder power users
Calendar-driven work
Personal task tracking
Home, health, family, and work lists
People who love tags a normal amount
People who do not love tags but need them anyway TaskFlow Studio helps your tasks flow from “I should remember that” to “handled.” Finally. Mostly. Tomorrow also exists.
