## What is Aera?

Replay your run. Understand your body.

Watch your Apple Watch and iPhone runs from the past week again, as a short film over the real ground, with your pace, heart rate and climb. Free.

Your nights, heart, effort and progress are read against your own usual, and every number opens a short note on how it was worked out and where it stops being reliable.

Aera works with the watch you already have, through Apple Health: Apple Watch, Garmin, Polar, COROS. Everything is worked out on your iPhone. No account.

YOUR RUN, AGAIN, IN 3D
Runs, walks, hikes and rides play back over the real ground, with pace, heart rate, climb and distance live on screen. Share one as a 20-second video. A replay needs the run's GPS route in Apple Health: Apple Watch and iPhone runs carry it, and Garmin exports and FIT, GPX or TCX files bring theirs in through Import.

EVERY WORKOUT, AGAINST YOUR USUAL
Splits, heart rate zones, pacing and heart drift against your own runs. Best efforts with their place among yours, like 2nd fastest of 41. How hard it felt, from 1 to 10. Trends that say whether a change is real.

A LOOP FROM YOUR DOOR
Pick a distance and Aera draws up to three loops from where you stand: on ground you know, new to you, or off-road. Or draw your own along real paths. Turn by turn on iPhone and Apple Watch.

YOUR NORMAL, NOT AN AVERAGE
Stress, strain, sleep and recovery are scored against what is usual for you. While your history is thin, Aera says so instead of guessing.

LAST NIGHT, AS IT HAPPENED
Your stages as they came, the hours you slept, and how far that sat from the need Aera learned from you. Your sleep score over weeks and months.

EVERY NUMBER, EXPLAINED
Tap a number and the Field Guide shows how it is built, the research behind it, and where it stops being reliable.

HOW'S TODAY?
Say how the day feels, or mark time off when you are ill or away. Aera reads your numbers with that in mind.

ANY WATCH, OR NONE
Each page says what it can read from what you wear, and what would add more. Link Polar directly and its nights and workouts come in on their own.

ALSO IN AERA
Body age beside your calendar age. Blood pressure from your cuff, or typed into the Health app, with a report for your doctor. Widgets for the Home Screen and the Lock Screen. An Apple Watch app for runs, walks and hikes.

FREE
Your scores every day, with their last 30 days. Your body age, your sleep reserve and your places. Loops, the route planner and turn by turn, with five saved routes. Every workout read, every personal best and your recap films. 3D replays of the last seven days. Every export of the last 30 days. Apple Health's own numbers, always.

PREMIUM
How your body age moved, month by month. Your whole history, and all of it to export. 3D replays of every outing, and of a route before you go. Your ways, all time. Every time on a walk. More than five saved routes. A report for yourself, and longer reports for your doctor.
Yearly, paid at once or in 12 monthly payments, starts with a free week. Or month to month, or once and yours for good.

PRIVACY
Your health numbers stay on your iPhone. No account, no sign in. Your scores are computed on your iPhone, and there is no language model anywhere in the app.

## Version history (last 5 releases)

### 4.0.1 — 2026-11-12

This update fixes a freeze. After updating to 4.0, Aera could stop responding a few seconds after opening. That is fixed, and so is a rare stop in the Map planner. I am sorry if it happened to you.

### 4.0 — 2026-11-09

Hello again. 4.0 is the biggest update Aera has had, and most of it is for runners: your run again in 3D, every effort against your own, and the watch you already wear.

YOUR RUN, AGAIN, IN 3D
The replay is rebuilt as a film: four live figures, camera views and map styles. Share it as a 20-second vertical video.

HOW HARD IT FELT
Tap 1 to 10 on any workout, saved to Apple Health with your OK. Best efforts say where a run sits, like 2nd fastest of 41.

TRENDS
Cardio fitness, resting heart rate, effort, endurance and more, each saying what changed and whether the change is real.

ANY WATCH, OR NONE
Garmin, Polar, COROS and every watch that writes to Apple Health now get full pages, and each page says plainly what it can read and what would add more. Link Polar directly for its nights and workouts. Import Garmin exports and FIT, GPX or TCX files with their GPS tracks, ready to replay, free for the past week.

HOW'S TODAY?
Tell Aera how the day feels, and mark time off when you are ill or away. Your scores and notes take it into account.

PREMIUM, REBUILT
Your scores every day, with their last 30 days, stay free, and so do the replays of the past week. Premium keeps your whole history, every replay and the longer reports, and the yearly plan starts with a free week.

ALSO NEW
- On your watch: pick the pages for each sport and follow turns.
- The Map opens on satellite. Turn and tilt it, and on a segment your best pass races your last.
- Your sleep score over weeks and months, and last night as a card to share.
- Blood pressure reports as a PDF, a spreadsheet or a QR code.
- At most three notes a day: your morning, How's today? and blood pressure.
- Siri starts, pauses and ends a workout. Plan a route from Control Center.
- A bigger Field Guide: 16 reads rebuilt and 10 new, each with its sources.
- A third look, Colour.

### 3.3 — 2026-10-11

Hello again! Since 3.2 I have been busy with three things: loops that work in the middle of a city, a lighter look, and more on your wrist. Here is what 3.3 brings.

LOOPS, DOWNTOWN TOO
Ask for a loop from a city centre and Aera now finds one, and it finds loops from more starting points. Search the Map for a place, switch on drinking water, and filter where you have run by sport or year. Leave a route you are drawing and it waits on the map until you resume.

A LIGHTER LOOK
The nature photographs are gone. Aera is lighter, with one drawn background everywhere, and the Map now has a light mode.

TODAY, AT A GLANCE
Three rings on Today: touch and hold one to see its score, or keep the scores showing. Timeline draws your day as one line, with your sessions, where the day is now and tonight's bedtime.

NEW: BLOOD PRESSURE
Readings from your cuff in Apple Health, with averages, a daily range chart, and mornings beside evenings. Give a reading a tag, like coffee or a short night. With Premium, build a report for your doctor as a PDF or a spreadsheet.

MORE ON YOUR WATCH
Double tap to mark a lap, set your pool length before a swim, and see your next turn on the map. With Premium, build your own workout pages and set a pace or heart window that taps your wrist when you drift out of it.

IMPROVEMENTS
- Fitness says how much room you have to train today.
- Stress shows your day as one line and names the tense stretches.
- Search the Field Guide by any word inside an article.
- Touch a split to see that stretch on the workout chart.
- Notification settings show what each note will say.
- Smoother sleep and heart charts, more natural translations, and plenty of small fixes.

### 3.2 — 2026-09-29

Hello, autumn! While you were out running, walking and sleeping (hopefully in that order), I kept teaching Aera one thing: getting you out the door. Here is what 3.2 brings.

PICK A DISTANCE, GET A LOOP
Open Plan on the Map and pick Loops. The loops you already run come first. Ask for a new one and Aera draws up to three from where you stand: Familiar, New to you and Off-road, or Cycleways on a ride. Size them by distance or minutes, or press and hold the map to start somewhere else. Loops lean onto waymarked trails and signed cycle routes, keep off ground too hard for your sport, and show their climb. A Sights loop passes the best-known places, numbered, with photos, and a viewpoint can be timed for the sunset.

EVERY TURN, SPOKEN
Follow a route with directions read aloud, on the Lock Screen too, even with no signal. Take a wrong turn and Aera says so.

YOUR ROUTES, YOURS
Drag the small ring on any stretch to bend a route, pull a corner, or tap a point to turn around there. A loupe shows the ground under your thumb, with Undo and Redo close by. Hold a route to rename it or give it another activity. Walks you repeat become routes of their own.

RUNS FROM YOUR WRIST
Record on your Apple Watch alone, with auto-pause, and feel each turn of a route. Your watch now opens on today's plan, then sleep, body and fitness, one crown turn at a time, with your sleep score and stages. The Smart Stack shows last night in the morning and bedtime in the evening. Start today's plan with Siri, Control Center or the Action button on Apple Watch Ultra. Every route carries its own map with contour lines, even with no signal.

TODAY'S SESSION, AND WHERE
Fitness Today picks the place as well as the session, and the coach opens the Map on loops sized to it, the best fit first, with a saved route that fits. Part of Premium.

ARE YOU GETTING FITTER?
Progress reads cardio fitness, pace at the same effort, resting heart rate and heart rate recovery as Fitter, Holding or Easing. Set your own max, resting and threshold heart rate, and every zone follows.

EVERY WORKOUT, IN ONE PICTURE
One chart for the whole session: pace with every split, heart rate shaded by your own zones, every hill, and pauses clearly named. Splits and interval reps show cadence, and elevation shows your real altitude and the true summit.

FLYOVER, AS A FILM
Flyover is now a short film of your workout that pauses at your photos, your fastest split and the top of the climb. Free for the last seven days, older workouts with Premium.

MAKE THE CARD YOURS
Edit a share card the way you edit a widget: rewrite any word, pick any colour, and every size still fits. A new Effort look shows how hard you worked.

EXPORT AND YOUR WHOLE HISTORY
Pick who a file is for. With Premium, a clear report for your doctor, with only the readings a doctor can use. Your map, routes and personal bests reach back through every workout, and years of workouts from another app's export come into Apple Health from Settings, with no duplicates.

SLEEP, IN ONE WORD
Sleep opens on a word for the night, then your score and time asleep, weighed the way the published studies do. Naps count, and never merge into last night.

FREE FOR EVERYONE
Recap films for your weeks, months and year, every personal best, and twelve months of every chart.

LIGHT, AND TEN LANGUAGES
Aera follows your phone into light mode and speaks ten languages, each now read by a native editor, with words on widgets, the watch and charts kept whole.

STEADIER
Aera opens in about a quarter of a second and page tops draw at once. No freeze after a sync. Steep climbs keep the clock running, and a day your watch missed stays empty instead of getting a recovery score.

### 3.1.1 — 2026-09-26

Hello, autumn! While you were out running, walking and sleeping (hopefully in that order), I was teaching Aera one new thing: getting you out the door. Here is what 3.1 brings.

PICK A DISTANCE, GET A LOOP
Aera draws up to three loops from where you stand: one on ground you know, one on new ground, and the quietest.

EVERY TURN, SPOKEN
Follow a route with directions read aloud, on the Lock Screen too, even with no signal. Take a wrong turn and Aera says so, then tells you when you are back on it. Got a GPX file? Open it from Files or a message and it is ready to follow.

YOUR ROUTES, YOURS
Hold a route to rename it, reshape it or give it another activity. Walks you repeat become routes of their own, named after the neighbourhood they start in. Routes point out the sights they pass, and you choose which ones.

RUNS FROM YOUR WRIST
Record on your Apple Watch alone, with auto-pause. Follow a route on your wrist and feel each turn, with the next corner on a complication.

TODAY'S SESSION, AND WHERE
Fitness Today now picks the place as well as the session: your usual loop on a good day, a shorter one when your body asks for it. Part of Premium.

ARE YOU GETTING FITTER?
Progress answers honestly: cardio fitness, pace at the same effort, resting heart rate and heart rate recovery, each reading Fitter, Holding or Easing. Predictions show whether your race times are getting quicker. You can now set your own max, resting and threshold heart rate, and every zone follows.

EVERY WORKOUT, IN ONE PICTURE
One chart for the whole session: pace with every split marked, heart rate shaded by your own zones, and every hill on the route. Start a workout from Home, Fitness or the Map.

SLEEP, IN ONE WORD
Sleep opens on a word for the night, then your score and time asleep. The score now weighs things the way the published studies do, so your numbers may shift a little. Naps count, and never merge into last night.

NOW FREE FOR EVERYONE
Recap films for your weeks, months and year. Every personal best. Flyover for anything from the last seven days. Twelve months of every chart.

LIGHT, AND TEN LANGUAGES
Aera follows your phone into light mode, and now speaks German, Spanish, French, Hungarian, Italian, Japanese, Portuguese (Brazil and Portugal) and Traditional Chinese. Reduce motion, higher contrast and colour-blind friendly colours are in Settings, Accessibility.

STEADIER
Aera opens in about a quarter of a second, down from three. The map stays smooth with thousands of trails on it, and a run survives the app closing.

3.1.1
• A route you save on your phone guides you on your watch too.
• A walk started on your phone and recorded on your watch keeps its true time and distance.
• Ending a workout on your phone stops it on your watch.
• The coach's recommended route opens with its loop already drawn.
• Suggested loops change from day to day.
• Loops follow the route style you choose for each sport, and can keep off busy roads.
• Ride loops reach 100 km and run loops 42 km.
• Surfaces and sights appear sooner, and their photos load faster.
• The Map asks for your location the first time you open it.
• Bedtime and wake times show in full in every language.
• Every screen, your watch and your widgets are fully translated.
• Fitness and Recovery open on days with missing or repeated data.
