4.Do vs Taska

4.Do

• People who plan with the Eisenhower or Covey four quadrants
• Android users who add tasks from the notification shade
• One priority matrix on Android, iPhone, iPad and Mac

Taska

• People who sort tasks by urgency and importance
• Keeping a record of the day without writing a journal
• Seeing the task matrix on the Lock Screen without opening an app

4.Do

• The vendor says Premium is needed for full access to all features but does not list what the free version leaves out.
• On the App Store, Premium is a subscription at $4.99 monthly or $29.99 yearly; no one-time purchase is listed there.
• Google Play shows in-app purchases of $1.99 to $29.99 per item without naming them or their billing period.
• No Windows or web version is listed, and some features exist on one platform only, such as the Quick Settings tile on Android and Siri on iOS.

Taska

• Apple devices only: the App Store lists iPhone, iPad, Mac and Apple Vision, while the vendor's site describes it as an app for iPhone and iPad.
• The App Store listing does not say which features need a membership, and the vendor's site has no pricing page.
• By design there are no folders, tags or projects.
• It requires iOS 18.4, iPadOS 18.4 or macOS 15.0 or later, and the wallpaper feature depends on a multi-step Shortcuts setup.

4.Do

Four-quadrant matrix

Tasks are grouped by urgency and importance, with an overview of all four quadrants or a focused view of one. Quadrants can be renamed and given custom colors.

Auto-advance and drag and drop

Auto-Advance adjusts a task's quadrant based on its due date, and drag and drop moves a task by hand when its priority changes.

Subtasks, repeats and attachments

Large tasks break into subtasks, tasks repeat at custom intervals with reminders, and images or files can be attached for reference.

Sorting, filters and tags

Tasks sort by due date, creation date or manual order, and filters and tags separate work, home and personal tasks. The view can switch between all tasks and a filter by status.

Quick capture

On Android, tasks are added from a persistent notification or a Quick Settings tile. On Apple devices, Siri, Spotlight, voice input and a photo scan add tasks.

AI suggestions, Calendar view and sync

The App Store version suggests a quadrant for a typed task using on-device AI, groups tasks by due date in a Calendar view, and syncs through 4.Do Cloud.

Taska

Eisenhower Matrix

Tasks go into one of four boxes by urgency and importance and are dragged between boxes as priorities change. Release notes describe keeping several matrices and swiping between them.

Focus timer

Tapping a task starts a timer with 15, 25 and 45-minute presets or a custom length, and the running session shows on the Lock Screen.

Calendar auto-log and Schedule tab

A finished focus session is saved to the iOS Calendar as an event. The Schedule tab shows the day on a timeline next to a monthly calendar.

Lock Screen wallpaper

A Shortcuts automation redraws the matrix as the Lock Screen or Home Screen wallpaper when the app opens or closes, or at a set time each day.

Widgets

Home Screen widgets show tasks without opening the app. A vendor notice says the March 2026 update rebuilt the set as 32 widgets.

iCloud and Reminders sync

Data syncs through iCloud with no sign-up, and release notes describe syncing tasks with Apple Reminders.
