I've been building a distraction free notes app called Zen for the past few months.

* It's built using Go and uses SQLite database for storage

* It's fast and uses less memory (~20MB) and CPU resources

* Supports standard Markdown with tables, code, etc

* It's built using as few dependencies as possible, so less bitrot long term

* Has search with BM25 ranking

* Designed thoughtfully with minimal color palette
