Task App Undo Redo: Instant Actions, No Delay (2026)

Under 50ms is the difference between undo that feels instant and undo that makes you wait. A task app's undo is only trustworthy when the reversal completes faster than you can notice: no spinner, no sync delay, no vanishing toast countdown.

Key takeaways

• Dooit is built to complete every action in under 50ms, so undo and redo happen with no perceptible lag (Dooit's own spec).
• Most apps split undo into three separate behaviors: undoing completion, undoing typing, and undoing deletion. They're not equally reliable.
• Todoist explicitly cannot undo a deleted task. Amazing Marvin can, via Ctrl/Cmd+Z.
• Todoist's completion-undo toast lasts only a few seconds, a hidden time pressure most comparisons ignore.
• Todoist Pro ($5/mo) is 16.7% cheaper than Superlist Basic ($6/mo); Amazing Marvin costs 60% more than Todoist Pro.

Why does task app undo/redo speed even matter?

Undo speed matters because a task app is only as trustworthy as its ability to reverse mistakes without hesitation. Delays, spinners, and vanishing toast windows make you double-check before you delete or complete anything, and that breaks flow. Dooit is built to complete every action, including undo and redo, in under 50ms.

• Keyboard-first users chain actions fast, so any lag compounds across a session.
• A slow or ambiguous undo forces you to slow down before deleting or completing tasks.
• Instant undo is a trust signal, not a convenience feature.

What lets you undo or redo actions quickly in a task app?

Fast undo comes from two things working together: a keyboard shortcut (Ctrl/Cmd+Z and its redo counterpart) and a backend that applies the reversal without a network round-trip or animation. Dooit pairs 20+ shortcuts with full undo and redo support and sub-50ms execution, so the reversal is visually instant, not just technically available.

• Keyboard shortcuts alone don't guarantee speed. The app's action-processing time is the real bottleneck.
• Confirmation dialogs and sync-dependent undo add perceptible delay.
• Local-first or optimistic-update architectures tend to feel instant; server-round-trip architectures don't.

How do you undo the last action and then redo it?

Undo and redo follow a near-universal pattern: Ctrl+Z (Cmd+Z on Mac) reverses the last action, and Ctrl+Shift+Z or Ctrl+Y restores it. Todoist, Amazing Marvin, Superlist, and Dooit all share this base pattern. The real difference is whether the action reverses instantly or waits on a toast, sync call, or confirmation step.

• Amazing Marvin maps Ctrl+Z to Undo and Ctrl+Y to Redo, with Cmd on Mac.
• Superlist enabled ⌘+Z and ⌘+Shift+Z across all text fields on Mac and Web, not just tasks.
• Dooit applies the same pattern with sub-50ms execution across its 20+ shortcut set.

How do you undo a typing action and still keep the redo available?

Typing undo means reversing text entry, like a task-title edit, without erasing your redo history. One undo should remove only the last keystroke batch, and redo should restore it exactly. Superlist extended this to all text fields, including list titles and task titles, which shows that text-undo is a separate behavior from task-level undo.

Text-field undo and task-action undo run on different code paths in most apps, so one can work while the other doesn't. Superlist's update covers list titles, messages, and task titles with ⌘+Z and ⌘+Shift+Z. Test this separately from deletion and completion undo when you evaluate an app, because it's easy to miss.

What shortcut redoes a previously undone action?

Redo shortcuts vary more than undo does. The common options are Ctrl+Y or Ctrl+Shift+Z on Windows and Cmd+Shift+Z on Mac. Amazing Marvin uses Ctrl/Cmd+Y; Superlist uses ⌘+Shift+Z. There's no single standard across task apps, so power users switching tools should confirm the key before trusting muscle memory.

• Amazing Marvin: Ctrl+Y (Windows) or Cmd+Y (Mac) for redo.
• Superlist: ⌘+Shift+Z for redo on Mac and Web.
• Dooit follows the same shortcut logic within its 20+ shortcut set, keeping undo/redo muscle memory consistent.

Completion, typing, or deletion: which kind of undo does your app actually support?

Undo splits into three separate mechanics most comparisons blur together: undoing a completed task, undoing typed text, and undoing a deletion. No app handles all three identically. Todoist undoes completions via a short-lived toast but cannot undo deletions at all, while Amazing Marvin extends Ctrl/Cmd+Z to deletions and Superlist extends it to text fields.

• Completion undo: Todoist shows a bottom-left pop-up for completed recurring tasks that lasts only a few seconds.
• Deletion undo: Todoist says deleted tasks cannot be restored, with no undo for deletion.
• Deletion undo (contrast): Amazing Marvin's recovery guide says Ctrl/Cmd+Z can undo a just-deleted item.
• Typing undo: Superlist rolled this out separately across all text fields, proving it's a distinct engineering problem.

Why deletion undo is the riskiest gap

Deletion undo is the riskiest gap because deleting a task is destructive and, in some apps, irreversible. Todoist states plainly that deleted tasks cannot be restored to the project. Delete by mistake and the work is gone. Amazing Marvin's documented Ctrl/Cmd+Z recovery is the safety net that behavior-focused comparisons rarely surface.

Why a time-limited toast isn't true instant undo

A time-limited toast isn't true instant undo because it puts a countdown on recovery. Todoist's completion pop-up appears at the bottom-left and disappears after a few seconds, so undo becomes a race. Genuine instant undo keeps the reversal on a keyboard shortcut with no visible timer, which removes the pressure to react before the window closes. As Dooit's own spec frames it:

No spinners, no loading, no lag. As fast as you can think.

Comparison: how do leading task apps handle undo/redo and pricing?

Across six task apps, deletion undo ranges from full keyboard reversal to no undo at all, and core paid pricing spans roughly $5 to $9/month. Todoist Pro at $5/month undercuts Superlist Basic ($6/month) by 16.7%, while Amazing Marvin's $8/month plan costs 60% more than Todoist Pro for a comparable single tier.

App	Deletion undo	Redo shortcut	Core paid price
Todoist	No undo for deletion	Not documented	$5/mo Pro
TickTick	Not documented	Not documented	Premium (paid)
Amazing Marvin	Yes, Ctrl/Cmd+Z	Ctrl/Cmd+Y	$8/mo
Superlist	Not documented for tasks	⌘+Shift+Z	$6/mo Basic
Any.do	Not documented	Not documented	$4.99–$7.99/mo
Dooit	Full undo/redo, sub-50ms	Standard pattern	$9/mo

Use this table as a quick reference before the app-by-app sections. Pricing reflects each app's core paid tier, not enterprise or team add-ons, and speed claims are based on documented behavior rather than independent lab testing.

Todoist: reliable completion-undo, but no deletion recovery

Screenshot: Todoist pricing page, August 2026.

Todoist gives you a brief undo toast for completed recurring tasks, but it states deleted tasks cannot be restored, a real gap for anyone who deletes by mistake. Pricing runs from free (Beginner) to $8/user/month (Business), with shortcuts like Q for Quick Add and Cmd/Ctrl+K for Quick Search.

• Beginner: $0, 5 personal projects, 3 filter views, 1 week of activity history.
• Pro: $5/user/month or $60/year, 300 personal projects, full reporting history.
• Business: $8/user/month, up to 500 team projects, 1,000 members and guests.
• Completion undo toast lasts only a few seconds; deletion has no undo at all.

If you're weighing Todoist against alternatives, our Todoist vs TickTick breakdown covers the wider feature trade-offs.

TickTick: strong shortcut coverage, undo behavior undocumented

Screenshot: TickTick download page, August 2026.

TickTick emphasizes keyboard shortcuts and command menus for mouse-free efficiency across six platforms, but its public help docs don't document undo or redo behavior at all. Because no source specifies how TickTick's undo/redo behaves or how fast it reverses, treat both its behavior and its speed as unconfirmed until you test them in-app. TickTick is a solid cross-platform pick if shortcut breadth matters more to you than a documented undo guarantee.

• Available on iOS, iPadOS, Android, Windows, macOS, Linux, and a browser extension.
• Feature set includes keyboard shortcuts, collaboration, integrations, and 40+ themes.
• Free tier allows 1 attachment/day (10MB max); Premium allows up to 199/day.
• No published Ctrl+Z-for-deletion guarantee. Test undo behavior before relying on it.

Amazing Marvin: explicit Ctrl+Z/Ctrl+Y mapping, including deletion recovery

Screenshot: Amazing Marvin pricing page, August 2026.

Amazing Marvin documents Ctrl+Z for Undo and Ctrl+Y for Redo in its shortcuts guide, and its recovery article confirms Ctrl/Cmd+Z can undo a just-deleted item, one of the clearer deletion-undo guarantees among these apps. Amazing Marvin runs a single $8/month plan with all 100+ features unlocked and a 14-day free trial.

• Ctrl+Z / Cmd+Z (Mac) = Undo; Ctrl+Y / Cmd+Y = Redo.
• Recovery guide explicitly recommends Ctrl/Cmd+Z after accidental deletion.
• $8/month or $96/year, unlimited tasks and projects, custom workflows, 14-day trial, no card required.
• 60% pricier than Todoist Pro's $5/month for a comparable single-tier plan.

Superlist: the only app that documents text-field undo separately

Screenshot: Superlist en page, August 2026.

Superlist shipped undo and redo for all text fields, including list titles, messages, and task titles, using ⌘+Z and ⌘+Shift+Z on Mac and Web. That granularity is a level of detail no competitor here documents publicly. Pricing starts free (5 private and 5 shared lists) with Basic at $6/month for unlimited lists and 25GB storage.

• Free: $0, 5 private and 5 shared lists, unlimited tasks and notes, 500MB storage.
• Basic: $6/month or $59/year, unlimited private and shared lists and sublists, 25GB storage.
• Text-field undo/redo for titles and messages is documented as a shipped update.
• 16.7% pricier than Todoist Pro at $5/month for its paid tier.

Any.do and ClickUp: cross-platform sync, less undo-specific documentation

Screenshot: Any pricing page, August 2026.

Any.do syncs tasks across Web, Desktop, iOS, and Android 24/7, and ClickUp offers broad feature depth, but neither publishes the granular undo/redo mechanics that Amazing Marvin and Superlist do. Any.do Premium runs $4.99–$7.99/month, and ClickUp Unlimited at $7/user/month costs 40% more than Todoist Pro's $5/month.

• Any.do Premium: $4.99/month annual or $7.99/month, adds recurring tasks, AI features, and location reminders.
• Any.do Family: $8.33/month for 4 members (annual) or $9.99/month, shared grocery list and projects.
• Any.do Teams: $4.99/member/month annual, unlimited boards and members.
• Any.do syncs 24/7 across Web, Desktop, iOS, and Android.
• ClickUp Unlimited ($7/user/month) costs 40% more than Todoist Pro ($5/user/month).

Dooit: instant undo/redo in a keyboard-first, single-plan task app

Screenshot: Dooit website, August 2026.

Dooit is built to execute every action, including undo and redo, in under 50ms, paired with 20+ keyboard shortcuts, natural language scheduling, a Kanban/list toggle, and goal and habit tracking. Disclosure: Dooit is our product. One honest limitation: its single $9/month plan (7-day trial) means no free tier for casual or budget-conscious users.

• Sub-50ms execution on every action, including undo and redo, with no spinners or loading lag.
• 20+ keyboard shortcuts with full undo and redo support.
• Natural language scheduling ('tomorrow,' 'next Friday,' 'every Monday') speeds up task entry between undo/redo actions.
• Kanban and list views switchable with one keystroke; goal tracking by week, month, year, and multi-year; daily habit streaks; real-time sync with a dedicated mobile app.
• Single $9/month plan, 7-day free trial, no tiers or add-ons. Simpler, but no free-forever option like Todoist or Superlist.

Frequently asked questions

Does Ctrl+Z work immediately in task apps, or does it need confirmation first?

It depends on the app. Amazing Marvin maps Ctrl+Z directly to Undo with no confirmation dialog, and its recovery guide recommends it for accidental deletions. Todoist, by contrast, has no undo option for deletions, so Ctrl+Z won't recover a deleted task there. Behavior isn't universal across apps.

Can you undo an accidentally deleted task instantly?

In Amazing Marvin, yes: Ctrl/Cmd+Z can undo a just-deleted item per its own recovery documentation. In Todoist, no: deleted tasks cannot be restored to the project, and there's no undo for deletion. Always check an app's deletion-specific undo behavior separately from its completion undo.

How long do undo notifications typically stay visible before disappearing?

Todoist's undo pop-up for completed recurring tasks appears at the bottom-left but lasts only a few seconds, which creates time pressure. Apps built for non-expiring reversal remove that pressure by keeping undo on a keyboard shortcut with no visible timer.

Do Todoist, TickTick, and Superlist all use the same undo/redo shortcuts?

The base pattern is mostly shared: Ctrl/Cmd+Z for undo is near-universal. Redo varies. Amazing Marvin uses Ctrl/Cmd+Y; Superlist uses ⌘+Shift+Z. TickTick's public docs cover shortcut breadth generally but don't confirm a specific redo key, so check in-app before relying on it.

Which task apps show a toast notification with an immediate undo button?

Todoist shows a bottom-left undo pop-up for completed recurring tasks, though it's time-limited to a few seconds. Superlist instead built undo/redo into text fields via keyboard shortcut rather than a toast. Toast-based undo and shortcut-based undo are different mechanisms with different reliability windows.

Is undo/redo speed different between web, desktop, and mobile task apps?

Documentation rarely specifies this, but architecture matters. Apps relying on server round-trips for undo tend to feel slower on mobile networks, while locally processed actions feel instant everywhere. Any.do confirms 24/7 sync across Web, Desktop, iOS, and Android, but doesn't detail undo speed per platform.

If instant, keyboard-first undo is what you're after, start free with Dooit and test how sub-50ms recovery feels in your own workflow.
