Air Fill builds fast, native forms that create and update records in your own Airtable bases – big tappable inputs, conditional logic, signatures, and submits that work even with no connection. Air Fill is an independent app from Knock Knock Bang. It is not affiliated with, endorsed by, or sponsored by Airtable. Airtable is a trademark of Formagrid, Inc., used here only to describe compatibility. If you build and run bases for your team, you know a browser form does the job at a desk. On a phone it gets cramped and slow. Air Fill gives you a fast, native way to create and update records in your own bases, right from iOS. WHAT YOU CAN DO • Build forms that map to any base and table, and create records in a tap. • Open an existing record and update it in place — change what needs changing, then submit. • Fill anywhere. Entries save on your device and send the moment you reconnect. • Show a field only when it applies, with conditional logic you set once. • Pick linked records fast with scoped quick-picks. • Capture a signature with a finger or Apple Pencil, saved straight to the record. • Attach photos and scan barcodes to fill fields. • Chain forms into Form Flows, and run them from the Shortcuts app. MADE FOR REAL FINGERS Select cards and chips sized for touch, clear date and number inputs, and a fill experience the non-technical people on your team can pick up without instructions. CONNECT YOUR WAY Sign in with Airtable, or connect with a personal access token. You choose exactly which fields each form shows. FREE TO START Fill up to three forms for free. Air Fill Pro adds unlimited fillable forms, linked-record quick-picks, signatures, and attachments. Air Fill Pro is an auto-renewing subscription: $4.99/month, or $39.99/year with a 14-day free trial on the annual plan. Your Apple ID is charged at confirmation of purchase. Subscriptions renew automatically unless turned off at least 24 hours before the end of the period; manage or cancel anytime in your App Store account settings.
