Should I choose Let’s Do or Outlook Calendar?

AppRanks cannot recommend one over the other from published marketplace data: the Slack Marketplace does not expose a rating or review base that separates them. Read both apps' detail pages for the feature breakdown, and compare against your own requirements rather than a headline number.

Which is faster to set up, Let’s Do or Outlook Calendar?

Both apps are one-click installs from the Slack Marketplace. AppRanks doesn't measure setup time directly, and the Slack Marketplace publishes no review base that would let us infer it for these two — read the recent reviews on each app's detail page for user-reported install experience.

Which works better for small vs large Slack Marketplace teams?

Let’s Do typically suits early-stage and growth-mode teams based on its published review base (0 reviews). Outlook Calendar typically suits early-stage and growth-mode teams based on its published review base (0 reviews). A larger review base generally means the app has been exercised at scale — relevant if you are processing high volume or handling enterprise compliance requirements.

Can I migrate data between Let’s Do and Outlook Calendar?

Migration support varies by app and category. Let’s Do and Outlook Calendar both publish their export options on their marketplace listing pages (or in their support docs); some apps offer one-click import from competitors, others require CSV. The fastest check: search "import from Outlook Calendar" in each app's help center. AppRanks does not track migration tooling directly — this is a category-specific capability worth verifying before commitment.

Let’s Do

Let's Do adds an easy-to-use task manager to Slack. You and your team are already in Slack – use it to handle your tasks as well. Assign tasks, set due dates, add notes and keep track of what needs to get done. Organize your team tasks. Ensure everyone is on track and on top of things. Add shared to-do lists to Slack channels to keep tasks focused and actionable. With the app, each channel in your Slack workspace becomes a to-do list easily accessed by the channel members. Each team member stays on top of their assignments from the to-do overview on the Let's Do home tab. To-do lists are easily shared with the members of a channel for multiplayer editing. Follow channels to keep track of the progress of the todos. Daily reminders are sent for to-dos that are due soon. New assignments and changes are notified as they happen. Notifications can easily be adjusted or toggled when needed. Use personal to-dos to keep track of the tasks that don't need to be shared. These can, for example, be used for your day-to-day planning, keeping track of personal goals, or saving meeting notes for later processing. Use repeated to-dos to keep routines running smoothly. You can automatically repeat to-dos monthly, weekly, biweekly, or even daily. The app is available wherever you are in Slack; use the /todo command, trigger it from shortcuts, or use the overview on the Let's Do home tab. Use Let's Do as your primary task manager, as a complement to an existing task management system, or to setup your own process around to-dos within Slack. → Bring order to your tasks today!

Outlook Calendar

Let your team know when you're busy and keep your calendar top of mind with up-to-date reminders in Slack. Available for Office 365 Outlook Calendar. Use Outlook Calendar in Slack to: • Automatically sync your calendar to your Slack status to let your team know when you are in a meeting, out of the office, or working from home. • See a holistic view of your daily schedule from Slack. • Get notified when an event is starting soon, and join a Hangout, Zoom, Webex, or Microsoft Teams meeting directly from the calendar reminder in Slack. • RSVP directly to event invitations, get updated when an event’s details change, and change your response as needed. • Configure channel notifications for shared calendar events. Here are some details to bear in mind about status sync: • Your status will not include the name of the meeting that you’re attending. • You can remove or update your Slack status at any time – the Outlook Calendar app won’t override any status that you’ve set yourself. • Only events that you accept will trigger a status update in Slack. • Slack will only sync with the primary calendar for the Outlook account that you’ve connected. • If there are overlapping events on your calendar, Slack will set your status to match the event that’s longer or that starts earlier. Notes: • Outlook Calendar for Slack is only available for Office 365. The app is not supported for on-premise Microsoft Exchange customers. • On-premise SharePoint installations or Office 365 plans hosted on a Microsoft national cloud deployment (including Office 365 U.S. Government, Office 365 Germany, and Office 365 operated by 21Vianet in China) are not supported.
