The software application Glide (link) enables you to create an app from a Google Sheet.
I use Google Sheets for all my data so the discovery of Glide has been very beneficial. I used data from RWC 2019 (link) to try out the basic functionality of Glide. I created two apps:
Referees at RWC 2019
The app includes a QR code for sharing:
Cards Given at RWC 2019:
This app has its own QR code too.
I am mindful that I have just started with Glide. I found their instruction videos very helpful (link). What I do like about the app is the potential for open sharing. Each app has its own search function and I think this will be particularly helpful.
Each app has its own url too for ease of reference.
