A morning with Aera
Every morning starts from the night you actually had. Here is what Aera reads, and what it does with it.
01 Last night
Hours asleep, the stages, how unbroken it was and your sleeping heart rate, measured against the sleep need Aera learned from your own nights. Watch sleep stages are an estimate, so they count for less, and Aera says so.
02 Overnight
Heart rate variability, resting heart rate, breathing and wrist temperature, each against your own last four weeks. Sleep is not an input, so recovery never turns into a second sleep score.
03 This morning
Your recovery, sleep, stress and recent training decide the call, with the reasons beside it. Free every morning, once Aera has a few weeks of your nights and workouts. Until then it says it is still learning.
04 Today's run
Aera writes today's session from the week you actually had: an easy 35 minutes, say, and nothing at all on a rest day.
05 Out the door
Tap the map and the line keeps to real paths, with the distance counting as you draw. Follow it turn by turn on your iPhone or Apple Watch, spoken if you want it, even with no signal.
How the call is made
Illustration. In the app every number opens an article that shows how it was worked out.
From early users
Matches how I feel
The numbers line up with how my body actually feels in the morning, sleep most of all. Closer than the sleep scores I was used to.
Clear at a glance
A design people like, with the data laid out clearly. A good mix of wellness and training.
Fast and simple
Quick, straightforward and easy to find your way around, with a lot inside.
What testers and App Store reviewers tell us, in our words.
The Field Guide
Tap a number and it opens a short article: how it was worked out, the research behind it with sources you can open, and where it stops being reliable.
“Apple Watch sleep stages are an estimate. Aera gives them less weight, and tells you so.”
From the article on your sleep score
After the run
Flyover turns your run into a short film, flying your route in 3D over the real ground. It pauses at your fastest split and the top of the climb, with pace, heart rate and elevation along the way.
Free for runs from the last seven days.
Your map
Tap the map and the line keeps to real streets and trails, with the distance counting up as you draw. Already have a route? Open the GPX file.
Along the way, Aera lists what you will meet from OpenStreetMap: springs, viewpoints, summits and more.
Turn by turn on your wrist, even with no signal. Spoken aloud if you like. Drift off the line and it tells you, then again when you are back on it.
The planner and turn by turn are free.
On your Home Screen
Widgets for the Home Screen and the Lock Screen: today's session, last night against your need, this morning's vitals against your usual, your week and your last run on a map. They show what the app shows. Not one of them prints a score.
On Apple Watch, today's read is on your wrist, and it records your walks, runs and rides.
Also in the app
Record a run on your watch alone, with auto-pause, and feel each turn of a route.
In every size, on the Home Screen and the Lock Screen.
Your week, month and year as short films, free.
Satellite, terrain and splits looks. Rewrite any word, pick any colour.
Raw data as JSON or GPX, free. Reports and every other format with Premium.

Questions
Aera is an iPhone and Apple Watch app that reads Apple Health and tells you each morning how hard to go: rest day, go easy, good to go or go for it. It reads your sleep, recovery, stress and strain against your own usual, plans routes on a map with turn-by-turn directions, and explains every number in a short article.
Yes. Recovery, stress, strain and your sleep score, the call for the day, the route planner, turn by turn, every workout read, every personal best and Flyover for the last seven days are free. Premium adds today's session, your sleep reserve, your places, older Flyovers, history past twelve months, reports and every export format.
There is no account. Aera reads Apple Health on your iPhone and works out every score there, so health numbers stay on your iPhone. There is no language model in the app. Product analytics stay off until you turn them on and never include health values.
An Apple Watch gives Aera the overnight heart and sleep signals most reads are built on. Without one, Aera works from what your iPhone records, like steps and workouts, and the reads that need a watch wait until there is data.
It learns your usual range from your own nights and sessions over several weeks, then compares each new day with it. While your history is thin, it says it is still learning instead of guessing.
No. Aera is for everyday wellbeing and training. Watch measurements such as sleep stages are estimates, and every article says where its number stops being reliable.
English, Hungarian, German, Spanish and French in full, and Italian, Japanese, Portuguese and Traditional Chinese in part.
