tasking

tasking

tasking is a local-first project and task manager for iOS. It is built around task dependencies: you define which tasks must be completed before others can start, and the app enforces those rules automatically.

Use it when a simple checklist is not enough, but you do not need the complexity of enterprise project software.

What makes tasking different

Most to-do apps treat every task as independent. tasking models real workflows:

  • If Task B depends on Task A, then B cannot start until A is done.
  • When prerequisites are incomplete, dependent tasks are marked Blocked.
  • The app prevents circular dependencies (for example, A → B → A).
  • A dependency graph shows how tasks connect visually.

All data is stored on your device. No account or sign-in is required.

Main concepts

Projects

A project is a container for related work. Each project can include:

Field Description
Name Project title
Client Client name and remarks
Due date Optional project deadline
Staff Team members who can be assigned to tasks
Milestones Named dates on the project timeline (cannot be after the project due date)
Remarks General project notes

Tasks

A task belongs to one project and can have:

Field Description
Title Task name
Notes Multi-line description
Priority None, Low, High, or Urgent
Due date Optional date-only deadline
Status New, In Progress, Done, or Blocked
Assignees One or more staff members from the project
Prerequisites Other tasks that must be completed first

Dependencies

A dependency means: prerequisite → dependent.

  • The prerequisite must be Done before the dependent can start.
  • A task can have multiple prerequisites.
  • You cannot create a dependency on the same task, a duplicate link, or a cycle.

Getting started

1. Create a project

  1. Open the app. You land on the Projects list.
  2. Tap + in the top-right corner.
  3. Enter a project name (required) and optional details.
  4. Tap Create.

Staff members are needed before you can assign tasks.

  1. Open the project.
  2. Tap the info button or choose Project Details from the menu (⋯).
  3. In Staff, type a name and tap Add.
  4. Repeat for each team member.

3. Create tasks

  1. Inside a project, tap + to add a task.
  2. Enter a title and tap Create.
  3. Tap the task to open its detail screen and add notes, priority, due date, and assignees.

4. Set up dependencies

  1. Open a task.
  2. In Prerequisites, tap Edit Dependencies.
  3. Search for a task and tap Add to make it a prerequisite.
  4. Tap Done.

Example: For tasks Book flights and Book hotel:

  • Add Book flights as a prerequisite of Book hotel only if flights must be booked first.
  • Direction matters: prerequisite → dependent.

5. Work through tasks

Open a task and use the Actions section:

Status Available actions
New or Blocked Start Task (only if all prerequisites are Done)
In Progress Complete Task
Done Revert to In Progress

If prerequisites are not finished, the app shows a message listing which tasks must be completed first instead of a Start button.

When you complete a prerequisite, dependent tasks are re-evaluated. If all prerequisites are done, a Blocked task becomes New and can be started.

Task list tools

Inside a project, use the menu (⋯) in the top-right:

Filter

Option Shows
All Tasks Every task in the project
Available Tasks that can be started now (New, or Blocked with all prerequisites done)
Blocked Tasks waiting on incomplete prerequisites

Sort

Option Order
Created Date Oldest or newest first (by creation time)
Due Date By due date
Priority By priority level

View Task Dependency

Opens an interactive dependency graph:

  • Each task appears as a node.
  • Arrows point from prerequisite to dependent.
  • Drag nodes to rearrange the layout.

On iPad and other large screens, sheets such as the graph and project details open full screen for easier editing.

Create Sample Tasks

When a project has no tasks, the menu offers Create Sample Tasks. This adds a realistic overseas business trip workflow with staff, milestones, assignees, and dependencies so you can explore the app quickly.

Project details

Open Project Details from the info button or the menu to edit:

  • Project name and remarks
  • Client name and client remarks
  • Project due date
  • Staff list (swipe to delete)
  • Milestones (name + date; milestone dates cannot exceed the project due date)

Changes are saved as you edit.

Task statuses explained

Status Meaning
New Ready to start (all prerequisites complete, or no prerequisites)
In Progress Work has started
Done Task is finished
Blocked Has prerequisites that are not yet Done

Status is managed by the app based on your actions and dependency rules. You cannot change status manually from the picker; use Start, Complete, or Revert instead.

Priority levels

Level Color (in list)
None Default
Low Blue
High Orange
Urgent Red

Priority affects sort order and how tasks appear in the list. It does not change dependency rules.

Deleting items

  • Projects: Swipe left on the Projects list, then confirm deletion. This removes the project and all its tasks.
  • Tasks: Swipe left in the task list, or use Delete Task on the task detail screen.

Deletion cannot be undone.

Tips

  1. Add staff before assigning tasks — assignees are chosen from the project staff list.
  2. Set the project due date first — milestone dates must fall on or before that date.
  3. Use the graph — when dependencies get complex, the graph makes the flow easier to understand.
  4. Try the sample project — use Create Sample Tasks on an empty project to see dependencies in action.
  5. Filter by Blocked — quickly find what is waiting on other work.
