Let's Do

About this app

Let's Do is a lightweight task management tool designed specifically for teams that rely heavily on Slack. It allows users to create task lists per channel, assign tasks using @mentions, set due dates, and monitor progress directly within Slack's interface. With features like pinned lists and recurring tasks, it simplifies workflow management for remote or hybrid teams. The app offers a 14-day free trial with no credit card required, making it easy to test. While it excels in usability and integration, it lacks advanced features like visual customization or external dashboards, positioning it as a 'good enough' solution for teams seeking simplicity over complexity.

Written by AI from measured evidence, scored out of 100.

Let's Do excels at doing one thing extremely well: providing lightweight, intuitive task management within Slack's environment.

The seamless integration and instant performance make it feel like a native feature rather than an add-on.

Measure by measure

Usability

Zero learning curve for Slack users with intuitive task creation via @mentions and slash commands. Perfect integration within existing workflow.

Design

Clean Slack-native interface with slash commands and pinned lists, but lacks visual customization options and drag-and-drop functionality.

Speed

Feels completely native to Slack with instant task loading and no performance lag reported during testing.

Security

Relies on Slack's OAuth and encryption standards, reducing vulnerabilities by eliminating separate login requirements.

Accessibility

Inherits Slack's accessibility features like screen reader support and keyboard shortcuts, but offers no additional customization options.

Growth

Strong niche appeal for Slack-centric teams, but faces competition from Slack's own native features and more robust alternatives.

Improvement areas

Lacks visual customization options like color-coding or priority indicators, limiting usability for power users
No drag-and-drop functionality for task sorting, making management less smooth and efficient
Offers no additional accessibility enhancements beyond Slack's features, potentially excluding teams with specific needs

Design & Usability

Let's Do embraces Slack's minimalist design philosophy completely, using familiar slash commands like /todo and keeping task lists neatly organized in pinned messages. The interface feels like a natural extension of Slack rather than a bolted-on third-party tool. Threads automatically attach to tasks for context preservation, and the lack of a separate UI significantly reduces cognitive load for teams already comfortable with Slack's environment. However, power users might find the design too basic, missing visual customization options like color-coding or priority indicators. The absence of drag-and-drop sorting feels like a missed opportunity for smoother task management.

Speed & Security

Performance is where Let's Do truly shines - tasks load instantly and interactions feel completely native to Slack's interface. During testing, there were no noticeable lags or performance hiccups, making it feel like a built-in feature rather than an add-on. Security leverages Slack's established OAuth implementation and encryption standards, which means fewer potential vulnerabilities since there's no separate login system to maintain. While this approach is efficient, it also means Let's Do doesn't offer additional security layers that some enterprises might require for sensitive task management.

Accessibility & Growth

Accessibility is handled entirely through Slack's existing framework, which includes screen reader support, keyboard navigation, and high-contrast themes. While this provides a solid foundation, Let's Do itself offers no additional accessibility enhancements or customization options, which could limit its usefulness for teams with specific accessibility needs. The growth potential is interesting - it perfectly serves the niche of teams that live in Slack but could be vulnerable if Slack decides to expand its native task management features. The simplicity that makes it appealing also limits its expansion into more complex project management territory.

Conclusion

If your team lives in Slack and you're tired of tasks getting lost in endless chat threads, Let's Do is absolutely worth trying. The 14-day free trial with no credit card requirement makes it a risk-free experiment. Just manage your expectations - this is a 'good enough' solution that prioritizes simplicity over advanced features. For teams needing robust project management with Gantt charts and complex workflows, you'll want to look elsewhere.

Suggestions for improvement

Adding task prioritization through color labels or urgency indicators would significantly enhance usability without complicating the interface.
Developing a lightweight cross-channel dashboard outside of Slack could provide valuable overviews without breaking the simplicity promise.
Expanding recurring task options beyond basic intervals would cater to more complex workflow needs.
While mobile functionality works through Slack's app, a dedicated offline-capable mobile experience could better serve teams on the go.
Finally, investing in accessibility enhancements beyond what Slack provides would make the tool more inclusive for diverse team needs.
