Thanks for thinking along, FWIW I hope it may inspire other readers as well. I was aware of option #0 and #1. #0 made me give up -eventually, after retrying- since it requires root because Google Keep has no public API. This is also why I was puzzled #1 claimed it did work (it didn't).
0) Keep for Pebble requires root (root is area 51 for me)
1) WatchNote never worked for me (only sortof, via Evernote, very buggy)
2) Infinite Notes doesn't use Google Keep (offline is nice though since I regularly lose internet access in the grocery store).
3) PowerNoter doesn't use Google Keep (voice command is interesting, but my shopping list isn't saved in English)
Perhaps I should ditch Google Keep as requirement, but the missus is very accustomed to that and doesn't tolerate yet another piece of software for grocery shopping.
