Nikki is a native Android client for Memos, the open-source self-hosted note-taking tool. It adds Todoist-style task management on top of your memos, with a Windows Phone Metro-inspired interface.

Tasks are parsed directly from markdown checkboxes in your notes. Write "- [ ] buy milk tomorrow 5pm p1 #shopping" and Nikki extracts the due date, time, priority, and tags — giving you a structured task view without duplicating data.

Features:
• Full Memos API integration (create, edit, pin, archive, delete)
• Rich markdown rendering with code highlighting, tables, and links
• Due dates (ISO, today, tomorrow, next monday, in 3 days)
• Times (12h/24h), priorities (p1-p3), reminders, tags
• Group and sort tasks by date, priority, list, or memo
• Android notifications with 4 priority channels
• Calendar integration for reliable reminders
• Offline-first with sync queue
• 3 themes (dark, light, AMOLED) and 20 accent colors
• Activity calendar, tag browser, and search
• Export/import backup as JSON
• Share text from any app into a new memo

Requires a running Memos instance (v0.22+). The name comes from the Japanese word 日記 (nikki), meaning diary.
