Aera: Sleep, HRV & Recovery

Your body doesn't run on averages. Aera reads your sleep, stress, strain, and readiness against your own baseline, then tells you what's actually happening. Not what happened to 10,000 strangers.

Everything runs on your phone. No cloud. No account. No data leaves your device. When you want a second opinion, export a clean file and keep a copy for your own analysis.

TODAY, AT A GLANCE

Open the app and your day loads as a living dashboard. Readiness, Stress, and Strain as a hero trio. A rolling seven-day sleep bar. A weekly digest that surfaces what actually changed. The background breathes with the hour, from Morning Bloom to Deep Settle.

SLEEP, DECODED

Your sleep score is built from five factors, not one vanity number. Duration, stages, consistency, heart rate, and recovery. Tap in and you see the whole night. Stages, HR journey, restlessness, vitals, and a narrative that reads like a friend explaining.

Sleep Lab opens twelve deeper views as your data matures. Tonight's forecast. Score Decoder. Bedtime pattern. Regularity. Momentum. Continuity. Fingerprint. Seasons. Each unlocks once you have enough nights to trust it.

FITNESS, VISUAL

Training Status front and center. Tap any workout and a 3D route flyover plays back your run in space. Splits color-coded by HR zone. A year-at-a-glance heatmap of every active day. Training load bands that show when you're Ready, Optimal, Pushing, or Strained. Recent workouts. Trends. A log you can scroll. Routes you can watch fly.

STRESS, REVEALED

A real-time curve of your nervous system, drawn from HRV throughout the day. Not a score that drops from the sky. You see the spikes, the drivers, and the zones. Sleep versus wake. Day versus night. What shaped today, side by side.

STRAIN, MEASURED

Training load scored against your own capacity. HR zone distribution. Training form. What the day actually cost your body. Not a calorie count. A cost-to-recover number.

READINESS, LIKE A BATTERY

Body Battery in a gauge you can read at a glance. Energy drivers broken out: sleep, strain, recovery. An effort window that tells you how hard you can push today without borrowing from tomorrow. A five-day recovery trend so you can see the slope.

FOUR LABS, ONE BODY

Sleep Lab. Your sleep observatory. Chronotype, deep sleep windows, REM patterns, tonight's plan.

Recovery Lab. Nine modules. HRV baseline, strain accumulation, sleep architecture, temperature, post-exertion recovery, quiet periods.

Performance Lab. What builds your fitness. HRV trends, training consistency, optimal dose, HR recovery, movement quality. Running modules unlock at ten runs: Race Readiness, Best Runs, Pace, Weather.

Seasonal Lab. The months your body thrives, and the ones it quietly fights through. Patterns built from your own years of data.

YOUR BASELINE, NOT POPULATION NORMS

Most health apps score you against a 25-year-old athlete or a lab average. Aera learns your rhythm over weeks and scores you against the only body that matters. Yours. Baselines adapt as you change.

YOUR DATA VAULT

Every metric Aera tracks, browsable by category. Scores, Sleep, Heart, Activity, Body, Mobility, Environment. Tap any metric to see the full history.

EXPORT ANYWHERE

Export 7 days, 30 days, 90 days, a year, all time, or a custom range. JSON for your own analysis. CSV for Excel or Sheets. A polished PDF for your doctor or your own records. Use it wherever you want.

PRIVATE BY DESIGN

No account. No cloud. No analytics. No tracking. Your health data lives on your iPhone. HealthKit is the only source. That's the whole design.

WHO IT'S FOR

People who want to understand their body, not compete with strangers. Runners, sleepers, parents, students, anyone who's been told their score is "normal" when their body clearly isn't.

If you trust your own rhythm more than the average, Aera is built for you.
