The record list app is part of Airtable Apps, a Pro plan feature. Apps let you extend the functionality of your bases: you can use apps to bring new information into Airtable, visualize and summarize your records in colorful ways, and even directly integrate your Airtable bases with your favorite apps.
The record list app creates a set of record cards from the records in a view to be displayed in the apps panel. You can sort and limit the number of cards shown in the app, making it useful for drawing attention to the most important records: for example, if you need to see the largest three deals in your sales pipeline, the five most recently published pieces from your editorial calendar, or all high-priority bugs.
After adding a Record App to your base, you'll need to select a table and view containing the records you want to display.
By default, the record list app will display every record in a view. If you want to limit the number of records displayed. click the Limit records toggle and type in the desired number.
By default, the records will show up in the app in the order determined by the view you're using. Clicking the Sort records toggle will allow you to add a sort to the records that appear in the app. This sort is applied persistently, meaning that the record list will reapply the sort automatically if the records in the view change.
