OneThought: Daily Journal & Diary

On-device · No accounts · No analytics

One thought
is enough.

A small, private place for a single thought a day. Daily prompts written on your iPhone, photos that turn into moments, and a quiet weekly reflection that's only for you.

What's inside

A journal that finds the moments
you forgot you wrote.

Every screen is built around the same idea: less work for you, more honesty in the page.

Suggested moments built from photos

Suggested

Your photos, clustered into real moments.

Photos taken within an hour of each other become a moment — with location, count, time-range, and an auto-title like "Saturday at Central Park". Tap one and the editor opens with the photos already attached.

  • Five refresh lenses cycle on every pull-down
  • Auto-widens scope after 3 refreshes — the panda announces it
  • Skip moments you don't want — they stay gone
Story Mode reflection reel

Story Mode

Your story, narrated as a reel.

Tap the blue-glass card on Reflections to play your journal as a 9-scene animated reel. Numbers count up, the panda flies in from a different edge each scene, and every metric is clamped to your real calendar — no inflated streaks.

  • Words written, longest streak, places, dominant mood, top theme
  • Hand-arranged polaroid stack of your own photos
  • Cinematic blue-glass palette, segmented progress like Stories
Places map with photo pins

Places

Every place you've been, on a map.

Apple-Photos-style circular pins show a hero photo from each place, with a count badge for clusters. Filter by year. Tap a pin to see what happened there — sampled evenly across the cluster, never just the same back-to-back shots.

Reflections with mood chart

Reflections

A weekly summary you didn't have to write.

Each week the on-device model weaves your entries into a quiet reflection. Mood chart, 12-month activity heatmap, themes word cloud, current and longest streak. Open it Sunday evening and let the week land.

"OneThought asks for a sentence. The rest is for you."

— What you'll feel about week two

Built around the small things

Twelve quiet details
that change how you write.

On-device AI

Daily prompts, weekly reflections, even photo-derived drafts — written by Apple Foundation Models on your iPhone. Never a server.

Tone-aware

Pick gentle, direct, or poetic. Prompts, the panda's voice, and the writing CTA all shift to match.

Apple-style places

Map pins are circular photo thumbnails with count badges. Filter by year. Photos never blank out.

Drag to reorder

Compose has a horizontal photo strip. Drag any tile to a new position. Tap × to remove.

The panda

A small mascot peeks from the right edge. Tap it for a contextual line. Auto-tucks back so it never covers content.

Five lenses

Recommended, Most photos, Newest, Favorites first, Surprise me. Pull-to-refresh cycles them.

Smart search

Literal matches always rank above semantic. A unique word always finds the entry that contains it.

Auto-save

Every keystroke. Compose uses one shared context so your words never get lost mid-edit.

Face ID lock

Optional biometric unlock with a 5-minute background timeout. Biometric data never leaves the Secure Enclave.

Export anytime

PDF, JSON, or plain text. Day One JSON import too. Your archive is yours.

Today widget

Today's prompt + your current streak on the home screen. Reads from a shared App Group, never the network.
