This is a todo/notes app. You can organise todos in lists, change the color and title of a list, and reorder lists. Lists can be further groupped into tabs. Everytinhg can be synced over Nostr fully encrypted (NIP-44). For syncing to work Nostr must be enabled in settings, identity set (you can generate a new key, scan existing or log in using NIP-55 apps like Amber or Primal). Set the same key on multiple devices to sync live between them. All notes and settings can also be exported/imported using a JSON backup.
