Native for Mac & iPhone

A morning decision,
not another dashboard.

Aera turns sleep, recovery, heart rhythm, and activity into one clear recommendation for today — scored on your own baseline, explained in plain language, computed on your device.

Aera dashboard on macOS — readiness, HRV, resting heart rate, sleep and activity load on one screen

Three scores, one answer

Your body already voted overnight. Aera counts the ballots.

Deterministic engines score every morning against your personal 14-day baseline — not a universal target. Then they agree on a single line: what today should be.

Readiness

HRV, resting heart rate, sleep, and recent load fused into one composite — with every contributor visible, never a black box.

Sleep

Restorative quality, not just duration. Stages, efficiency, debt ledger — and a bedtime that actually repays what you owe.

Activity load

A daily strain target tuned to your recovery, with ACWR and monotony guards so a big week never silently becomes an injury.

Made for the desktop

The first health app that actually lives on your Mac.

Not a phone port. A real desktop experience with a two-column command center, keyboard shortcuts, a menu-bar summary — and a notch island that greets you with your scores every time you sit down.

Notch island — readiness, sleep, and today's plan one glance up.
Menu-bar tiles — your key signals, customizable, always in reach.
⌘K coach, ⌘1–5 navigation — health data at typing speed.

Every screen earns its place

Depth when you want it. Silence when you don't.

Aera Trends — readiness trend and sleep stage hypnogram — **Trends** — watch your baseline move, then open any day and drill into every signal.

Aera Insights — circadian alignment and recovery signals — **Insights** — your strongest hours, sleep need tonight, stress rhythm, and pace of aging.

Aera Journal — daily check-in with evidence progress — **Journal** — 30-second check-ins that Aera correlates against next-day recovery. Association, not causation — and it says so.

Aera Coach — private local coach grounded in your signals — **Coach** — grounded in today's numbers. Private local rules by default; Gemini only if you opt in.

And in your pocket

Same brain, iPhone reflexes.

Apple Health and Fitbit (via Google Health) fuse per metric, per day — detailed data wins, provenance is kept, and totals are never double-counted across sources.

Private by default, honest by design

Scored on your device

Readiness, sleep, and strain are computed locally by deterministic, reproducible engines. No account required. Your keys live in the Keychain, never in the cloud.

AI on a leash

The coach defaults to private local rules. If you enable Gemini, it receives a compact, consented daily summary — never your raw minute-level history.

No fabricated numbers

Sample data is always labelled. Every score shows the measurements behind it. If Aera doesn't know something, it says so instead of inventing it.
