## What is Liner Notes?

Your day, journaled for you.
Liner Notes is an auto diary and voice journal that drafts your day from your photos, sleep, steps, heart rate and conversations, and keeps the time you spend with the people who matter as memories. No account. Your records stay on your iPhone.

PHOTOS, SLEEP, STEPS WRITE YOUR DAY
Your places, photos, plans, sleep, steps and workouts are already a draft of the day. Read it, change only what you want, and keep it. On days you'd rather talk, one line into the mic is plenty.

YOUR HEART RATE, TENSE OR RELAXED
With Apple Watch, your heart rate and heart rate variability (HRV) are compared with your usual self at that time of day, so a timeline shows when your body was tense and when it was relaxed. Plans, places, workouts and sleep sit alongside. After a workout, see how your heart rate came back down.
This feature is for keeping and reflecting on your days. It is not intended for diagnosis or medical use.

TIME WITH PEOPLE, IN THEIR WORDS
Keep a conversation from a spoken note, and it's transcribed on your iPhone and split by speaker; summaries are made with Apple's Private Cloud Compute. The recording is deleted once it's text. Whether to tell people in the room is up to you. Conversations with people you name become part of your memories of them.

FROM APPLE WATCH, TOO
One press on your wrist starts recording. Your iPhone takes it from there.

HEART RATE AND VOICE AS YOU TALK
Your heart rate, the pitch of your voice, how much each of you talked, and laughter line up over a conversation, so you can see where it came alive.

SEE HOW YOUR RELATIONSHIPS SHIFT
Who you spent time with, and on what. People become glass particles and topics become capsules that shift as time plays. Liner Notes also tells you in plain words who appeared for the first time and who you haven't seen in a while.

A PICTURE AND A SONG FOR EVERY DAY
Each day's entry gets a picture and a song that fits. Each morning, a short note picks up from the day before, and at the end of the week, a letter to you arrives from seven days of records.

YOUR RECORDS STAY ON YOUR IPHONE
- There is no account
- Your diary and conversations are stored on your iPhone
- You choose where text is created in Settings: on your iPhone, Apple's private cloud, or OpenAI. OpenAI is used only with your consent, while you subscribe or during the preview
- Export every record anytime as Markdown or as a full copy

NO STREAKS, NO GUILT
No streak counters, no "you missed a day" messages. While you're away, the automatic record keeps going, and it's waiting when you come back.
