OneThought: Journal & Diary
Mindful, on-device, private
Free · Designed for iPad. Not verified for macOS.
Your journal becomes a real book — flip pages with a page-curl preview, customise the cover, share the PDF. On This Day now works from day one.
One thought is enough.
OneThought is a small, private journal that lives on your iPhone. Open it, write a sentence, close it. The rest is for you.
QUIETLY INTELLIGENT
Daily prompts and weekly reflections are written on-device by Apple Foundation Models. Your text never reaches a server. Pick a tone — gentle, direct, or
poetic — and the prompts (and the panda's voice) shift to match.
SUGGESTIONS FROM YOUR PHOTOS
OneThought clusters your photos into real moments — events with location, count, and time-range — and offers each one as a starting point for an entry.
Tap a card and the editor opens with the photos already attached and the title pre-filled. Pull-to-refresh cycles through five different lenses
(Recommended, Most photos, Newest, Favorites first, Surprise me) so the same library always feels fresh. Refresh three times and OneThought widens the
time scope automatically — the panda lets you know.
STORY MODE
Tap the blue-glass card on Reflections to play your journal as a 9-scene narrated reel. Streak, words, places, dominant mood, top theme, photo collage.
Numbers count up, the panda flies in from a different edge each scene. Every metric is clamped to your real calendar — no inflated streaks.
PLACES
Apple-Photos-style circular pins on the map. Each pin shows a hero photo from that place with a count badge for clusters. Filter by year. Tap to see what
happened there.
WEEKLY REFLECTION
Each week the on-device model weaves your entries into a quiet summary. Mood chart, 12-month activity heatmap, themes word cloud, current and longest
streak. Always optional, always editable.
A SMALL PANDA
A mascot peeks from the right edge of every screen. Tap it for a contextual line. Its voice follows your prompt tone. Auto-tucks back so it never covers
content.
The Calendar tab is here.
Browse your timeline day by day. Every day in your Suggestions scope is laid out as a real photo card from your library, so it actually looks like the time you've lived. Tap any day to see your entries, your suggested moments, and a one-tap shortcut to write for that day — even if it's already passed.
The biggest update to OneThought yet — your journal becomes a real book can flip through.
PAGE-CURL BOOK PREVIEW
Generate your Journal Book and tap to read it like a real hardback — pages curl as you swipe, the same animation Apple Books uses. Cover photo, title, colour and typography all flow through to the printed PDF.
JOURNAL BOOK REDESIGN
A new designer experience for building your book — a tilted hero cover preview at the top, stat tiles for entries / words / span, and dedicated cards for every option (title, cover photo, style, colour, typography). The Generate button now uses your chosen accent colour for a cohesive feel. Tap the cover preview to inspect it at full size.
COVER PHOTO FIX
Picked a cover photo and got a black page in the exported PDF? Fixed. We now embed the cover via PDFKit so it renders correctly in iOS Files, Quick Look, Mail, AirDrop, and any third-party PDF reader.
ON THIS DAY — FROM DAY ONE
The "On this day" section on Today no longer waits a year before showing anything. New users see real photos taken on today's date in past years, pulled from your photo library. Tap a card to start a journal entry pre-filled with that photo. Once you've built up entries from past years on this date, those take priority.
EXTRA POLISH
• Voice entries
• Generate PDF throttles double-taps
• Long entry titles now wrap correctly in the printed PDF
• Memory footprint when generating large books is significantly smaller
PRIVACY, AS ALWAYS
Everything stays on your iPhone. Your photos never leave the device. Entries sync via iCloud only if you turn it on. No accounts, no servers, no analytics.
