Slack timer: countdown, Pomodoro and focus timers that still work in 2026

"Slack timer" means three different things depending on who is typing it: a countdown for a meeting or a launch, a Pomodoro timer for focused work, or a timer that tracks work hours. Slack itself has none of the three. There is no live countdown you can post in a channel, no built-in Pomodoro cycle, and no native time tracking. What Slack does have is a small kit of native tools that cover most of the need, a thin and partly abandoned set of timer apps, and a few claims circulating in older guides that are no longer true. This page covers all three intents, verified against Slack's own documentation in August 2026.

Full disclosure: we make asyncmate, which is not a timer app. It comes up in exactly one section below, the work-hours one, and we say so when it does.

What Slack can do natively

Three built-in tools cover the timer-shaped needs that do not require a ticking display.

/remind is the nudge. It takes natural language and handles recurrence:

/remind me to stretch in 25 minutes
/remind #team to update the deploy doc every Friday at 3pm

Two things changed in recent years that older guides miss. Reminders now live in the Later tab and fire in Activity, not in a Slackbot DM. And as of 2026 you can no longer remind another person: /remind @colleague is gone, only me and #channel work. Recurring reminders also cannot be edited, only deleted and recreated, and everything fires in each person's own profile time zone.

Scheduled messages are the one-shot future message. Write the message, click the arrow next to Send, pick a time. It works on every plan, up to 120 days ahead, with a limit of 30 scheduled messages landing in the same channel per five minutes. A "time's up" message scheduled 25 minutes out is the closest native thing to a countdown, minus the counting.

/dnd plus an expiring status is the native focus timer. This pair is underrated:

/dnd for 25 minutes

then set a status like "🍅 heads down" with the expiry at 30 minutes. Notifications pause, the status clears itself, nothing to install. The honest caveat: DND silences banners and shows a moon icon, but it does not change your presence dot or stop Slack marking you away after ten minutes of inactivity. Do Not Disturb is not the same thing as looking busy.

What none of this gives you: a visible countdown in a channel, work and break cycles, per-person speaking timers, or reminders aimed at other individuals. Paid plans add Workflow Builder, which can wait up to 7 days with its delay step and then post a message, which is how the DIY Pomodoro workflows below are built. Despite what a few third-party guides claim, Workflow Builder is not available on the free plan; that is straight from Slack's own feature page.

Countdown timers: the thin part of the App Directory

Here the honest news is that the options are weak. The most visible countdown app in the Slack Marketplace, Slacount, is free but shows every sign of abandonment: its assets date from 2018, its site's copyright reads 2018, and its install button uses a deprecated authorization flow that may simply fail on a modern workspace. Try it if you like, but do not build a launch ritual on it.

For most countdown needs the practical answer is unglamorous: a scheduled "time's up" message for the async case, or a browser timer on the shared screen for the live case. If the countdown is for a standup or retro, dedicated standalone standup timers exist precisely because Slack and its huddles have no per-person timer at all. Huddles get you audio, screen share and AI notes, but no clock; on the free plan they are 1:1 only, capped at 30 minutes.

Pomodoro in Slack: three tiers that still work

Ordered by effort, all verified alive in August 2026:

Zero install. The native pattern above: /dnd for 25 minutes plus a tomato status with an expiry. Two commands instead of one, but it works on every plan and cannot be abandoned by a vendor.

One install. Focus Mode by Geekbot is free, sets your status and DND for a chosen focus block, and tells teammates what you are working on. Doropomo adds proper work and break cycles, to-do lists with pomodoro counts, and reports. Both are backed by active vendors. RoundPie is the freemium pick if you want a desktop timer that mirrors into Slack status and DND.

Power user. On a paid plan, Workflow Builder's delay step can wait 25 minutes and post "pomodoro done", though a running delay cannot be cancelled. Or connect an external Pomodoro app through Zapier or webhooks: Pomofocus and PomoDone can flip your Slack status on timer start and stop. One warning that saves an afternoon: any tutorial that mentions Slack "legacy tokens" or the old reminders API predates the 2023 changes and no longer works. The modern route is an OAuth app with the profile-write scope, which is exactly what the integrations above do for you.

Timing a standup, and the option of no clock

Timeboxing standups is standard advice for a reason. Agile guidance caps the meeting at 15 minutes, sometimes with 90 seconds per person. The drift data says the cap does not hold: industry analyses put the average standup at around 22 minutes against the scheduled 15, only about 12% of meetings actually finish inside 15 minutes, and one widely-cited Atlassian-attributed estimate puts the cost of overrunning standups near $283 per employee per month. Treat the exact figures as estimates; the direction is not in doubt. Add the context-switching research, which finds interrupted work takes about 23 minutes to resume, and a "15-minute" standup quietly costs each person most of an hour.

A timer in the meeting fixes the length. It does not fix the more common complaint, which researchers found is not duration but format: standups that feel like status reports to a manager rather than information shared between peers.

The other option is to remove the clock entirely. An async standup has no meeting to timebox: everyone answers the questions in Slack on their own time inside a window, and the team reads one digest. No timer, no drift, no interruption in the middle of focused work, which pairs nicely with the Pomodoro section above. The honest trade-offs: a blocker raised async waits until someone reads it, and a channel of updates nobody reads is worse than a short meeting. Our Slack standup bot is built around that format, digest and blocker tracking included.

If you meant tracking work hours

About half the people searching "slack timer" want a work-hours timer, so here it is plainly. For start-stop timers with minute-level records, Toggl Track and Harvest have live Slack integrations with slash commands; Clockify's Slack tie-in goes through connectors rather than a native app. For teams that need hours per project rather than billable minutes, the alternative is skipping the timer and logging hours once a day. That daily-log method is what asyncmate does (this is our product, and it is not a timer), and the full comparison of timers, spreadsheets and daily logs is in how to track time in Slack, with the feature itself at Slack time tracking.

FAQ

How do I set a timer in Slack? Slack has no real timer, so pick the nearest tool: /remind me in 25 minutes for a nudge, a scheduled message for a "time's up" post in a channel, or /dnd for 25 minutes plus an expiring status for a focus block. For a visible countdown you need an external timer on a shared screen; the in-Slack countdown apps are largely abandoned.

Does Slack have a Pomodoro timer? Not built in. The closest native pattern is /dnd plus a status that expires when the pomodoro ends. Focus Mode by Geekbot (free) and Doropomo do it properly, with the status, DND and cycles handled for you.

Can I set a reminder for someone else in Slack? Not anymore. As of 2026, /remind accepts only me or a #channel; reminding another person directly was removed. Older guides still showing /remind @person are out of date. The workaround is a channel reminder or a scheduled message in a DM.

Does Slack have a countdown timer for channels? No, and the App Directory's countdown options are thin: the most visible one, Slacount, appears frozen since 2018. A scheduled message at the deadline plus a reminder partway is the reliable native substitute.

How far ahead can Slack schedule a message? 120 days, per Slack's developer documentation, with a limit of 30 scheduled messages posting to the same channel within any five-minute window. Recurring scheduled messages need Workflow Builder, which is a paid-plan feature.
