To add an app to your base, go to your base and click the apps button in the top right corner to show the apps panel. Next, click the + Add an app button. This will bring up the apps gallery, which you can look through to find the appropriate app for your needs.

A few things to note about adding apps:

• You need creator permissions to add apps to a base.
• Every collaborator on a base sees the same apps.
• You can add multiple copies of the same type of app.
