You can use MobileSheets to work with music files, but there's a catch for Word documents. MobileSheets is designed to work best with PDFs. The easiest way to go about it is to convert your Word files into PDFs, and then you can use them with your page-turner foot pedal. Since you mentioned using only the free Adobe app, you won't be able to modify those PDFs after conversion, but you can find free Word-to-PDF converters online.
If you need to edit those Word files before converting them, consider upgrading to Microsoft Office Professional subscription. It's a handy option for managing and editing Word documents across devices.
