Why Use Slack Apps? – The Difference Between Slack Apps & Bots

If you’re using Slack, you’re already familiar with bots. These automated tools can perform simple tasks, like sending reminders or answering common questions. However, Slack apps take things to the next level. Here’s why you should consider using them:

Advanced functionality: While bots are great for simple tasks, apps can do more complex things. For example, they can integrate with other tools you use, like Google Drive or Trello. This means you can do things like create a new Trello card directly from Slack without leaving the app.

Better customization: A Slack app can be customized to fit your team’s specific needs. You can choose which features to enable or disable and even create your custom integrations. This means you can tailor Slack to work how you want it to.

Improved efficiency: Using Slack apps can streamline your workflow and save time. For example, you can use an app to automatically schedule meetings or track your team’s project management.. This means you can focus on more important tasks rather than getting bogged down in administrative work.

Increased collaboration: Slack apps help facilitate collaboration among team members. For example, you can use an app to create polls or surveys or to share files and documents. This means everyone can work together more effectively, regardless of their geography.
