Slack is where a lot of work happens — and where a lot of it leaks away. The right apps turn it from a notification firehose into something closer to a control panel: standups run themselves, decisions get made in a poll instead of a 30-minute call, files and calendars surface without tab-switching, and repetitive tasks get automated. The wrong move is installing twenty bots at once and drowning in noise.
Below are the Slack productivity apps that genuinely earn their place, grouped by the problem they solve. Each is a real, well-known tool described at a high level — install deliberately, not all at once.
Async communication & standups
Geekbot
Geekbot runs asynchronous standups and check-ins directly in a channel. It messages each person on a schedule, collects their answers, and posts a tidy summary — so distributed teams can skip the daily live meeting and still stay aligned.
Loom
Loom lets you record a quick screen-and-camera video and drop the link straight into Slack. It's ideal for walkthroughs, demos, and explanations that would take paragraphs to type — async video that saves a meeting.
Decisions, polls & team culture
Polly
Polly adds polls and surveys to Slack so you can gather a quick decision, pulse-check, or piece of feedback without leaving the conversation. Useful for everything from "where should we eat" to recurring team sentiment checks.
Donut
Donut pairs teammates at random for intros, coffee chats, and informal connection — then nudges them in Slack. It's a simple way to keep culture alive on remote and distributed teams where hallway moments don't happen on their own.
Focus, scheduling & calendars
Clockwise
Clockwise analyses your calendar and reorganises meetings to create longer blocks of uninterrupted focus time. Connected to Slack, it can sync your status to your calendar so colleagues know when you're heads-down.
Calendly
Calendly removes the back-and-forth of booking meetings — share a link and let people pick a slot from your real availability. The Slack integration lets you grab and share scheduling links without leaving a thread.
Google Calendar & Google Drive
Slack's native Google integrations bring your schedule and files into the app: Google Calendar can post your daily agenda and meeting reminders, while Google Drive surfaces shared files and notifies you of comments and access requests. Both are first-party and included with Slack.
Automation & workflows
Zapier
Zapier connects Slack to thousands of other apps and lets you automate workflows without code — for example, posting a Slack message when a form is submitted or a deal closes. It's the glue for wiring Slack into the rest of your stack.
Slack Workflow Builder
Workflow Builder is Slack's own no-code automation tool. You can build forms, onboarding flows, and triggered messages right inside Slack — handy for standardising recurring requests without adding a third-party app.
Task & project management
Asana or Trello
Asana and Trello both connect tasks and projects to Slack, so you can create, assign, and update work without switching tabs and get notified in-channel when things change. Pick Asana for structured project management or Trello for a lighter, board-based approach.
Presence & availability
Stay Green On Slack
Stay Green On Slack keeps your presence dot green on a schedule you choose, running from our servers so it works even when your computer is asleep — useful for async workers who don't want to be penalised for stepping away. Full disclosure: this is our own tool. Try it free here →
How to build your stack (without the noise)
You don't need all of these. Start with the one or two problems that cost your team the most time — usually meetings and context-switching — and add the matching app. Standups eating your mornings? Geekbot. Calendar chaos? Clockwise and Calendly. Repetitive copy-paste between tools? Zapier or Workflow Builder. Add deliberately, review notification settings as you go, and remove anything nobody's using. A lean, intentional Slack beats a cluttered one every time.
Frequently Asked Questions
What are the best Slack productivity apps?
The best Slack productivity apps cover the main ways teams lose time: async standups (Geekbot), polls and decisions (Polly), focus time and calendar optimisation (Clockwise), async video (Loom), automation (Zapier and Slack's native Workflow Builder), and task management (Asana, Trello). Native integrations for Google Drive and Google Calendar, plus scheduling links via Calendly, round out a strong stack. The right set depends on where your team actually wastes time.
How do I add an app to Slack?
Open your workspace and click Apps in the sidebar (or browse the Slack App Directory at slack.com/apps). Find the app you want and click Add to Slack, then approve the permissions it requests. Depending on your workspace settings, you may need a workspace admin to approve the installation first.
Are Slack apps free?
Many Slack apps offer a free tier that is enough for small teams, and most use a freemium model where advanced features, larger team sizes, or more usage require a paid plan. Native tools like Workflow Builder and the Google Drive and Calendar integrations are included with Slack itself. Always check each app's pricing page, as free limits vary widely.
What Slack app keeps my status active?
Stay Green On Slack keeps your presence dot green on a schedule you set, running from our servers rather than your computer. It is useful when you step away briefly or work async but do not want to be penalised for a grey or away dot. It runs independently of whether your machine is on or asleep.
Do Slack apps slow down your workspace?
Well-built apps run server-side and do not noticeably slow Slack down. The bigger risk is notification overload from installing too many bots at once. Add apps deliberately, review their channel and notification settings, and remove anything your team is not actively using.
