Read full description

ZattaMemo is a memo app for jotting things down quickly β€” and rediscovering them through your home screen widget. β–  Jot It Down, That's All You Need Just type and save. No extra steps, no setup. Designed for the moment an idea hits β€” capture it before it slips away. β–  Rediscover with Widgets Add a widget to your home screen and your saved memos appear at random. Forgotten ideas and TODOs catch your eye when you least expect it. Available in small and medium sizes. Tap to jump straight to the full memo. 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. Even the roughest notes become searchable and filterable after the fact. Six preset tags are included: Idea, TODO, Shopping, Work, Personal, and Later. 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. A one-time (non-subscription) upgrade unlocks unlimited memos, widget filtering (starred / tag), image attachments, and adding memos from the share sheet. Note: ZattaMemoLite has been renamed to ZattaMemo. Same app, same data. Jot it down, rediscover later. A simple memo app that's just right.
