I was using a loyalty cards app from the app store but noticed it kept consuming more storage space on my phone (the app size kept getting larger). I remembered that I could replicate the apps behaviour in Glide and did just that.
Here’s Loyalty Cards Template - Loyalty Cards Template | No Code App | Glide
Users can add their own loyalty card details (manually) and use the barcode to scan and earn points from the various providers. I’ve been using this app personally since I built it and till date, works without any issues!
