The long version

How it works

The home page says what the app does for you. This page says how, part by part.

The part you do every day

Logging a meal, without typing

Nobody quits a food diary because it was inaccurate. They quit because it was three minutes of typing, four times a day. So there are three ways in and none of them is a form.

A day's food in the app: a ring reading 1,260 kcal with carbs 167 g, protein 63 g and fat 38 g beside it, 500 mL of water under a hairline, and the ways in — Add a meal, Water, and seven saved meals.
  1. 01

    Open a plate

    A sitting rather than an entry, because that is what a meal is. Everything you had goes on the same plate, and the plate goes in once.

  2. 02

    Point the camera, or just say it

    Scan the barcode and the figures come off the label, not out of somebody’s estimate. Or say “I ate 100g of chicken breast” — read on the phone, by Apple’s offline recogniser. Or type two letters: everyday foods are built in, packaged products from Open Food Facts follow underneath.

  3. 03

    Keep the ones you repeat

    Give the plate a name and the same breakfast goes in with one tap tomorrow. Fix a figure later and the correction follows everywhere it counted.

And then it leaves you alone

The screen it opens on

A dashboard nobody else has

It reads 28 kinds of reading from Apple Health, plus your sleep and the workouts your watch recorded — then hands you the screen. No default layout you have to live with, and no tile you cannot take off.

Two tiles from the dashboard: Movement showing 3,653 steps, 9 flights and 2.45 km, and Food showing 1,038 kcal as a macro ring with carbs, protein and fat beside it.
  1. 01

    Pick the figure

    Anything Apple Health holds, grouped the way you think about it rather than by which device wrote it. Pin one to a single device where your watch and your phone disagree.

  2. 02

    Choose the shape

    Seven of them, from a number to a scatter. Set the span — a day, a week, a year — and attach a goal if it has one.

  3. 03

    Put it where you want it

    Drag the grid into your own order. Any tile opens onto a small dashboard of its own, which you also build.

Six kinds of tile

The other half of it

And a recorder for the part Health cannot see

Apple Health knows you moved for fifty minutes. It does not know that eight of them were the third set of a squat at 90 kg. So the app records the workout itself, and files it where the rest of your numbers live. Logging is free; reading a heart rate monitor while you do it is Unlimited.

01
The workout

A workout, monitor or no monitor

Start a workout and log sets as you go. 48 exercises, each asking only for what it is measured by — weight and reps for a bench press, time for a plank. Anything not on the list is typed in, and keeps its own chart.

  • 48 exercises catalogued
  • Custom workouts you repeat
  • Or write your own
A week of training: 3 workouts, 1h21 total, 123 average bpm, a button to build a new custom workout, and the month’s workouts — two runs and an hour of strength with 1 exercise and 360 kg — each with its own heart rate trace.
02
Route

Where you actually went

Distance, pace and climb read off your own GPS track rather than estimated, and every kilometre gets its own split. Share one and the first and last 200 metres come off first — a route map is a map of where you live.

  • Your own GPS track
  • Split by kilometre
  • Trimmed before it is shared
A route drawn on Apple Maps through Soho and Covent Garden, above three figures: a distance of 1.5 km, a pace per kilometre, and 0 m of climb.
03
Progression

Every exercise keeps one line

Any period adds up by workout and by exercise: time, weight lifted, sets, best set. Open a row for the whole history of that movement. Bench is bench, whichever workout it sat in.

  • Weight lifted and sets
  • Best set per workout
  • One history per movement
A month broken down by workout and by exercise: Run twice for 20 minutes at 122 bpm, Strength once for an hour at 125 bpm with 1 exercise and 360 kg, then Bench press across 1 workout, 3 sets and 360 kg with a best set of 20×8.

And underneath both

Your own data, read properly

A tile is only as good as the reading behind it. These three are where the app does the most work — and each one shows what it did.

01
Balance

A score that shows its working

One number from sleep, movement and food, with a page behind it showing what each contributed. No figure the app cannot explain.

  • Three inputs, shown
  • Per-input marks
  • No black box
The Balance card reading 83 out of 100, "Good · all three are level", with the week trending underneath and bars for sleep 88, movement 81 and food 80.
02
Sleep

A night as a shape, not a total

The stages as they actually ran, every wake marked. Then the same night as four numbers.

  • Stages in order
  • Wakes marked
  • Seven nights behind it
A night of sleep drawn as four lanes running from 00:29 to 07:00, above a breakdown of deep 1h18, REM 60m, light 3h40 and 3m awake.
03
Heart

The whole day, not the headline

Every hour as a low-to-high bar, your resting rate as the line through them. One average is not a day you can ask questions about.

  • Hourly low–high
  • Resting as a baseline
  • 30-day trend
A day's heart rate from 56 to 179 beats per minute, drawn as hourly low-to-high bars with the resting rate of 62 as a dashed line and the peak of 179 marked in the early evening.

The part that leaves the phone

Made to be sent to somebody

Almost everything here happens where only you can see it. Two things are built to be handed to somebody else, and both say exactly what they carry.

Your data.Your phone.Your rules.

Apple Health is only ever read, unless you ask the app to write to it. No account, no server. The one thing that leaves — a weekly challenge score, once you connect Game Center yourself — is listed in the privacy policy.

10 feats, 40 ranks

Earned once, kept for good

The same for everyone, and permanent once earned. Nothing you did before you arrived counts towards them — which is what keeps the wall worth looking at.

  • The Cross-Trainer
  • In the Zone
  • The Iron Streak
  • The Traveler
  • Early Riser
  • Triple Threat
  • Desk Jockey Defeater
  • Hydration Hero
  • The Regular
  • The Double-Digit Club

Four ranks each. Triple Threat, all the way up:

  • Bronze
  • Silver
  • Gold
  • Master

The interesting part

Built on a few refusals

What this app refuses to do is the part worth reading.

The arithmetic behind every figure is on the how the numbers work page. What it costs is on the home page.
