Welcome to the community!

I'm not sure what do you mean by an HTML system. If your POS stores its data in a Google Sheet, then yes can build an application based on that same sheet.

Absolutely, I've worked on something similar before. If you're using a template to build your app, you can usually integrate it with Google Sheets for your point-of-sale system. It's a handy way to keep your sales data organized. If you run into any hiccups along the way, just ask for help. And here's more info on which apps to use on Android. Good luck with your app project!
