Show HN: PaperMono, e-ink fridge magnet shopping list with mobile web page
PaperMono is a new e‑ink fridge magnet that functions as a digital shopping list. Users can add, edit, or remove items through a responsive web interface accessed from any mobile device. The magnet syncs changes in real time, displaying the updated list on its low‑power e‑ink screen, aiming to replace paper notes with a reusable solution.
