Airtable is like having the power of a database in the form factor of a spreadsheet. Sure you can use a sheet for a database, we have lots of times.
But there are limitations with that.
Airtable allows you to create a base with as many tables as you like, you can lookup data from other tables, use formulas like sheets, upload images, create a form to input data and much more!
Favourite feature: Mobile App is really slick & sorting data into views is a time saver
