About this app

Retro Notebook brings the warmth of a leather-bound diary to your phone: a simple, fast and beautiful notebook app. And now your notebook comes with an AI writing assistant.

New in v5.0.0:
• AI writing assistant: tap ✨ in any note to summarize it, pull out the key points, turn it into bullet points, fix spelling and grammar, or finish a half-written thought.
• Tone & translation: rewrite a note in a formal, friendly, kind or playful voice, or translate it into any of 14 languages.
• Works on your selection: select a passage and only that part changes. Replace the note with the result or add it to the end — and undo it if you don't like it.
• Title & tag suggestions: stuck for a title? Get three, plus tags that fit the note.
• Your own commands (Premium AI): "Turn this into an email", "sort by date", "keep only the numbers"… whatever you can think of, applied to your note.
• Privacy first: only the text you're working on is sent. Locked notes are never sent, and you can exclude any note from AI entirely.
• Transparency: everything the AI writes is marked, and you see how much of your allowance an action will use before you run it.
• Try the writing assistant a limited number of times with a free account.

You don't need an account to take notes or keep a journal — the app works fully offline. Signing in is only needed for cloud sync and AI.

More highlights:
• Journal mode: your days on a calendar, a page for each one, a timeline and a gallery of the days with photos. Free on your device, cloud sync with Premium.
• Writing prompts & streak: a question for the days you don't know what to write, themed packs, and a count of the days you write in a row.
• Mood tracking: log your day with one tap. Monthly summary free, month-by-month trends with Premium.
• On This Day: read what you wrote a year ago today.
• 5 retro color palettes to make the notebook yours — all free.
• Cloud sync: keep your notes identical on every device.
• Note version history: last 3 versions free; 30 days of history and side-by-side comparison with Premium.
• Share links: share a note through an open or password-protected link (Premium).
• Backups: free to your device as JSON or PDF; a cloud copy and the full history with Premium.
• Focus Mode: write on a clean, full-page screen.
• Checklists for to-do and shopping lists, multiple tags and pinned notes.
• Rich text: bold, italic, underline, strikethrough, collapsible headings and lists.
• Add images, drawings, links and voice notes to any note.
• Reminders, home screen widgets and ready-made templates (Meeting Notes, Shopping List, Recipe).
• PDF export: turn one note or all of them into a notebook-style PDF (Premium).
• Lock the app with a password or fingerprint; lock individual notes with Premium.
• Advanced search: filter by date, tag, category and attachment type.
• Document scanning (OCR): photograph text on paper and turn it into editable text.
• Trash, list or grid view and colorful categories; font size, color and typeface are up to you.
• Tablet layout: your list on the left, the open note on the right.

About Premium: Premium unlocks the Premium features above, an ad-free experience and an AI allowance that renews every month. Premium AI adds your own commands and a much larger monthly allowance. Monthly, yearly and lifetime plans are available; the lifetime plan also includes a monthly AI allowance. Eligible accounts get a free trial on the yearly plan — cancel before it ends and you won't be charged. Billing is handled by Google Play, and you can cancel anytime.

Write your stories and memories, keep a journal, and share your notes with the people you love.

A little too simplistic, but great look! Have to change text manually each time, rather than saving in settings. **Update: Developer attentive and quickly replied. I would buy this instantly if it had vintage looking notebook covers on a "shelf" to look at like "Notebooks" app by DroidVeda LLP. Love the look and feel of this.

Dates are not correct. It's correct when writing, but after saving, it show the 9th month instead of August.
