I keep turning my Google Sheets into phone-friendly webapps, and I can’t stop – Ars Technica

For things that are bigger than a note or dry-erase board but smaller than paying for some single-use, subscription-based app, I build little private webapps with Glide. You might use something else, but Glide is a really nice entry into the spreadsheet-to-app milieu. The apps it creates are the kind that can easily be shared and installed (i.e., “Add to Home Screen”) on phones, tablets, or desktops, from a browser.
