This definitely isn't the main usecase; it's mostly used as a spreadsheet application.

But, I use it for a few random tools.

I have an app I made that shows schedules. Rather than using a DB and building out an admin interface myself and giving people access to it, it just pulls from the Airtable DB.

I also often use it to export data to, so having signups or things like that go into Airtable rather than a DB.

I could use a DB for all of these, but Airtable's UI is super nice and makes it really pleasant to edit (vs a crappy form I set up)
