A NEW PERSPECTIVE ON EVERYDAY LIFE
Health, nutrition, time, wellbeing, and finance.
Your tools. Your context. A clearer picture.
MEET YOUR PERSONAL INTELLIGENCE PLATFORM
Five domains. One shared perspective.
Start with Home. Follow what matters.
A little more
understanding,
every day.
Friday, September 4, 2026
Sleep, meals, time and a moment to reflect. Follow a number to its source, or ask what changed.
An unhurried morning. A colorful lunch. A long walk home. Nothing extraordinary, just a day I want more of.
5 fewer hours than the previous week. Explore the calendar records before drawing a conclusion about how your time felt.
Explore the experience we’re building. Changes stay in this tab for your visit; device connections are planned.
THE BIGGER PICTURE
A busy calendar. A change in sleep. The meals you enjoyed and the moments you wanted to remember. Your apps hold the pieces. Metric Diary is being built to help you understand how they fit together.
ONE PERSONAL INTELLIGENCE PLATFORM
A shared view of the things that matter. Choose your domains, pin your metrics, and make the picture yours.
Sleep, activity, recovery and the signals that shape your everyday rhythm.
Meals, macros, hydration and timing, with room for the foods you enjoy.
Calendar load, focus and available device usage, seen in context.
Reflections, check-ins, habits, hobbies and the moments that matter.
Spending, balances and goals as part of your whole life.
KEEP THE TOOLS YOU LOVE
Metric Diary is the understanding layer above your specialist apps. Their records, your context, one connected history.
Choose supported apps and records. Add a reflection or a missing detail when you want to.
A shared Home, consistent trends and a personal timeline, with the source behind each number.
Ask Metric Diary is designed to explain verified calculations, with dates, sources and gaps in view.
01 / HEALTH
Start with your day. Follow a change. Keep every signal connected to where it came from.
Friday, September 4, 2026
Apple Health · Apple WatchTime asleep, excluding awake time. Review several nights alongside your own routine.
Source and date stay attached to every reading. Wearable measurements are estimates; availability varies by device. Planned connections are shown below.
02 / NUTRITION
A photo, a label, a barcode. A quicker start, with the final say always yours.
Meal recognitionReview the ingredients and their portions. Adjust oils, dressings, and anything the camera cannot see.
Photo nutrition is an estimate. Review portions before logging.
Recognition starts the entry. Your review makes it yours.
Adjust an ingredient, correct a label, or enter a meal yourself.
Every added meal updates the selected day’s diary and nutrition totals.
03 / TIME
Your calendar tells one part of the story. Focus sessions and available device-usage records can add another. See where your time goes, and how the pattern changes.
Weekly wrap-up
90 minCalendar events describe scheduled time, not confirmed attendance. Calendar-open time and recorded focus sessions are different measures.
Meeting load, recurring commitments, and calendar-open time across selected calendars. Start with Google Calendar, with more sources planned.
Compare recorded focus sessions and meeting-heavy weeks with activity, sleep, and your own reflections.
Device usage depends on platform permissions and availability. Automatic iOS Screen Time import is outside the initial U.S. release.
04 / WELLBEING
A thought, a feeling, a personal goal. Journal entries, check-ins, habits, hobbies, and life events give the numbers a little more meaning.
A check-in that feels human.Mood, energy, and a few honest words.
Find your way back.Dates and themes keep the moments within reach.
What gave you energy today?
Guitar practice, reading, cricket, or something entirely yours. Custom metrics and goals stay within Wellbeing.
Mark a new job, a move, or the start of a routine. Revisit changes alongside your numbers without assuming one caused the other.
Started a new work routineLife event · Added by you
Mood, stress, energy, focus and habits are optional. Keep a rhythm that helps you reflect, with space to skip a day.
ONE DAY. THE WHOLE STORY.
Select a date. Your meals, movement, calendar, and reflections move together.
“An unhurried morning. A colorful lunch. A long walk home. Nothing extraordinary, just a day I want more of.”
Shared context helps you notice patterns. It does not establish what caused a change.
05 / FINANCE · IN DEVELOPMENT
What comes in. Where it goes. What you’re working toward. Personal finance belongs in the story of your everyday life, too.
Balances, income, and categorized spending across supported accounts. Spot a change without opening every banking app.
Keep subscriptions and repeat bills in view. See what’s coming up and where small expenses start to add up.
Follow category budgets and savings milestones, with progress you can understand at a glance.
Planned for supported U.S. financial institutions, with a read-only connection and your authorization. Bank availability and refresh times will vary.

Availability depends on the source, device, membership, permissions, and completed records. A missing measurement stays missing.
Wrist temperature requires Series 8 or later, any Ultra, or SE 3, with sleep tracking enabled. Apple Health shows baseline changes after about five nights; its developer connection supplies nightly wrist-temperature readings. Blood oxygen depends on model, region, and software, and is unavailable on SE models.
Read source guidanceWHOOP 4.0, 5.0, and MG track steps across all memberships. Steps can be shared through Apple Health or Health Connect; the public WHOOP API does not currently document steps. Other records depend on membership, device, and processing. Recovery and Strain retain WHOOP’s own scales.
Read source guidanceSleep, Readiness, activity, heart measurements, temperature deviation, and available blood oxygen records can be shared through Oura’s account connection. Gen3 and newer rings need an active Oura membership. Readiness stays separate from WHOOP Recovery; temperature is a change in nighttime skin temperature, not a core-body reading.
Read source guidanceCoverage depends on the contributing app, your permissions, and the Health Connect version and features on your phone. A supported record type does not mean every wearable supplies it. WHOOP Recovery, Strain, and Oura Readiness use their respective account connections.
Read source guidanceYour signals keep their identity. WHOOP Recovery and Oura Readiness stay separate. HRV trends keep their measurement method. When a record arrives through more than one connection, its source helps us recognize the overlap.
BEYOND WEARABLES
Additional source categories are being developed in stages. Availability and permissions will be explained before you connect.
Google Calendar first; device calendars and Microsoft Calendar are being considered for later stages.
Explore TimeAvailable nutrition records, reviewed food entries, check-ins and your own reflections fill out the picture.
Explore NutritionReviewed imports and future account connections. Institution coverage and provider availability are still being evaluated.
Explore FinancePlatform-dependent. Android access is being evaluated; automatic iOS Screen Time import is outside U.S. V1.
Apple’s availability guidanceASK METRIC DIARY · IN DEVELOPMENT
Ask what changed across your health, nutrition, time, wellbeing, and finances. The app is being designed to calculate the facts first, then explain them with the evidence in view.
Dates, sources, missing records, and uncertainty belong in the answer. Associations are not presented as causes.
You averaged 7h 21m across seven nights this week. Saturday was your longest night at 8h 10m; Monday was your shortest at 6h 30m.
Calculated from recorded values. Sources and periods stay visible; a change alone does not establish its cause.
