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.

Every set, written down.

  • One tap a set. The rest timer starts itself, last time’s numbers sit beside the row.
  • Your heart rate live, in five zones set from your own maximum — so an easy day stays easy.
  • A run draws its own route, pace and splits. Log a set from the Lock Screen.

Logging is free. Live heart rate and analytics are Unlimited — one month free, then £39.99 a year.

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 — each with its own heart rate trace.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.

Or just know where you stand.

  • Your weight as a trend, not a number that jumps.
  • Resting heart rate, HRV and blood pressure, over a week or a month.
  • A ring to close each day — steps, water, protein — if you want one.
The Vitals screen: a resting heart rate of 62 down 5 in thirty days, HRV of 50 up 19, and the day's range from 56 to 179 drawn hour by hour.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.

Every morning

Two questions, answered before you ask.

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.

Was yesterday a good day?

  • One number out of your sleep, your food, your movement and your training.
  • And a page behind it showing exactly how it got there.
The Sleep screen: 6h32 last night, 18 minutes under average, the stages drawn from 00:29 to 07:00, and the last seven nights as bars against a 6h50 average.

Why are you tired?

  • Your night as a shape: light, deep and dreaming, in the order they happened.
  • Time asleep, kept apart from time in bed. Most people are surprised by the gap.

The part you send

One week, one friend, one number.

Three competitions, Monday to Sunday, measured in something you can say out loud in a group chat. Each one states what it refuses to count before the week starts.

01 / 03

Most Walked

Most ground covered on your own feet. Nothing to log, no kit to wear.

Scored onKilometres on foot

RuleWalking and running only — a bike ride is not a walk.

The Climber

Most flights climbed. Won by taking the stairs.

Scored onFlights climbed

RuleUp only — going back down earns nothing.

The Workout

Most minutes of deliberate training. Every session counts.

Before you ask

Questions

Do I need a heart rate monitor?

No. A monitor adds a live heart rate to a workout; it does not make one. Everything else runs on Apple Health alone.

Does it work with my Apple Watch?

Yes, through Apple Health — there is nothing to pair. The one thing that needs more is a live heart rate on a workout you record here: for that you need a chest strap or a watch that broadcasts over Bluetooth, which an Apple Watch does not.

Do I have to type every meal?

No. Scan the barcode, or say “I ate 100g of chicken breast” out loud. Everyday foods answer from the second letter, and a plate you name goes in with one tap tomorrow.

Does my friend need the app?

Not to be invited — the invitation is how they find it. They do need an iPhone: challenges run on Apple’s Game Center, which is what lets two people compete without either making an account.

Is there really a free version?

Yes, and it does not expire: the dashboard with your last seven days, the food log, every workout you log, every badge, all three challenges. Paying buys two things — further back than a week, and what a heart rate monitor adds.

What happens when the free month ends?

Your subscription starts, or you cancel before then and it costs nothing. Either way you keep the app: the dashboard goes back to seven days and nothing you recorded is deleted.

What actually leaves my phone?

One number per challenge per week, and only after you connect Game Center yourself. No readings, workouts, sleep or measurements are ever uploaded.

The long version is on how it works. Anything else lives on the support page.

Where it all goes

  • No account. Nothing you record leaves the phone unless you ask.
  • Your training and your food log back up to your own iCloud. Turn it off whenever you like.
  • A monitor is optional. Challenges use Game Center. Food figures come from Open Food Facts.
