How much free space do I need on my device to install Slack?

The Slack app is a moderate download that varies by device and update, and it tends to grow over time as it caches messages, files, images, and previews from your workspaces.

Is it safe to download and install Slack on my device?

Slack is safe to install when downloaded from the official Google Play Store or Apple App Store, which scan and verify apps before they reach you. Avoid unofficial APK sites, which can bundle tampered versions.

How much time will it take to finish downloading Slack?

Downloading Slack usually takes a short time, though it is a bit larger than a simple messaging app. On a fast Wi-Fi connection the download and install often finish within a minute or two.

What are the possible reasons my download or installation keeps failing?

If Slack keeps failing to install, start with storage, since a nearly full device often blocks the process. A weak or interrupted internet connection is another frequent cause, so switch to stable Wi-Fi and try again.
