With the upgrade, the widget can also show starred memos only, or filter by tag. β–  Organize Later with Hashtags Type #hashtags in your memo and they're automatically recognized as tags.

Over time, your own tagging system takes shape naturally. β–  Export and Put Your Notes to Work Export your memos in plain text, CSV, or JSON format. Copy to clipboard or share to other apps. Paste into AI tools to sort, categorize, or brainstorm from your raw notes. Your quick scribbles become input for something bigger. β–  Export and Restore Export your memos as JSON, and import them back anytime. Useful for restoring data after reinstalling, or moving between devices. β–  More Features - Star important memos for quick access - Bulk actions: archive, restore, or delete multiple memos at once - Search by keyword or filter by tag - All data stays on your device β€” no server, no account, no tracking β–  Feature List - Create, edit, archive, and permanently delete memos - Tag system (auto-extracted hashtags) - Favorites (star) feature - Bulk operations (select, archive, restore, delete) - Keyword search and tag filter - Export (text / CSV / JSON) - Home screen widget (small and medium) - Jump to memo detail from widget - Widget filtering: starred only / by tag (Upgrade) - Unlimited memos (Upgrade) - Attach an image to your memos (Upgrade) - Add memos from the share sheet (Upgrade) β€” About the Upgrade β€” All core features are free.
