Specs
Pros
Pro supports backlinks and hierarchical hashtags
It adopts the bi-directional links concept, which is hot recently in note-taking apps. It also adopts inline hierarchical hashtags. The combination is unique. It allows users to adopt the Zettelkasten style while maintaining a canonical hierarchy for the notes.
Pro local-first, with iCloud sync option
All notes are stored locally on the device with iCloud sync option, contrary to the common practice that sends notes back to and stores on developer's servers. This is completely private and secure, and users won't need to worry about privacy or app's continuity because their notes will always be there.
