I've written a simple, free, and ad-free iOS app to manage my Kaffelogic Nano roasts at home.
While I mainly wrote it specifically for myself, maybe other people can also benefit from it
Roast information can be written to and subsequently read from NFC tags (I put NFC stickers on my containers).
The app requires iOS/iPadOS 17.2.

If anyone is interested in beta testing new features, DM me and I'll put you into the TestFlight group.
