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.
