Airtable Forms can't be used within the mobile app... you would need to use a mobile web browser to fill out an Airtable Form.

On a mobile web browser, your prefilled forms should work properly.

However, one thing I should point out is that nowadays, the preferred way of prefilling forms is to use Fillout’s advanced forms for Airtable, which is 100% free and lets you update Airtable records directly from a form with no prefilling necessary at all!

Thats right — no prefilling necessary. :)

Even if you don’t want to update existing Airtable records and you’re just trying to create brand new records in Airtable, it’s much easier to prefill forms with Fillout, because they give a variety of different ways of prefilling — including the incredible ability to dynamically pre-fetch a record from Airtable using a simple URL, which can then be used to prefill fields on your form. (No more complicated URLs to prefill an entire form.)

Even better, Fillout offers hundreds of features that Airtable’s native forms don’t offer, including the ability to create PDF files from a form submission, create new linked records with a form, display Airtable lookup fields on forms, control access to a form via SSO or email domains, perform math or other live calculations on your forms, accept payments on forms, collect signatures on a form, create multi-page forms with conditional paths, and much more.

I show how to use a few of the advanced features of Fillout on these 2 Airtable podcast episodes:

• Using Fillout to create an eSignature approval process with PDF file creation.
• Using Fillout to create an order entry form with line items.

Hope this helps!
