Jiraiya
Read full descriptionHide full description
Book ideas rarely arrive while you are at your desk. Jiraiya for iPhone is the notebook for catching them on the spot. Your notes sync through iCloud to your Mac with the same Apple Account, and the Jiraiya Mac app brings them into your manuscript. You write the book on Mac; iPhone is where you gather the material. CAPTURE ON THE SPOT โข Capture ideas with text, photos, or voice โข Add notes quickly from widgets, Siri, Shortcuts, or the Action Button โข Keep the capture time and, when permitted, location โข On supported devices, Sennin Mode suggests tags and writing prompts on device (requires an Apple Intelligence capable device) REREAD THE BOOK YOU WRITE ON MAC Browse books created on Mac and synced through iCloud, organized by act, chapter, and section. When rereading sparks a thought, save it as a new Field Note. DASHBOARD View the days, time, and characters you wrote on Mac, plus your KDP sales summaries, in Dashboard. Switch between Writing and Sales performance. In Writing, choose a book and a period (7 days, 30 days, 3 months, or 1 year). Records and summaries are created on Mac and arrive through iCloud; iPhone is view-only. Only time and character counts are recorded, never the text itself. KDP sales appear only after you explicitly enable sales summary sync on Mac. Original Excel files, ASINs, KDP Dashboard estimates, and Payment Reports are not uploaded to iCloud. JIRAIYA PRO Your subscription is shared with the Mac app. On Mac, unlimited books, EPUB Reader preview, PDF export, Focus Mode, EPUB export, and M4B export are Pro features. The free Mac version includes one book. Manuscript writing and file export also take place on Mac. iCloud sync requires the same Apple Account on each device. Jiraiya Pro is an auto-renewing monthly or annual subscription. The price appears on the App Store purchase screen.

ZattaMemo is a memo app for jotting things down quickly โ and rediscovering them through your home screen widget. โ Jot It Down, That's All You Need Just type and save. No extra steps, no setup. Designed for the moment an idea hits โ capture it before it slips away. โ 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. โ 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. โ 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. โ Export and Restore Export your memos as JSON, and import them back anytime. Useful for restoring data after reinstalling, or moving between devices. โ 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 โ no server, no account, no tracking โ 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) โ About the Upgrade โ 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.
