Aera: Health & Readiness

New in 3.0: a map that draws every path you have covered, ten Home Screen widgets, and a rebuilt workout read. Every number still opens the article that made it.

Your watch counts the workout. Aera tells you what it was.

Every session gets a read: the effort it took, how it sat against your own usual, what the ground did to it, and what it leaves for tomorrow. Then every number opens the article behind it, with the method and the limits named.

READ AGAINST YOU, NOT AN AVERAGE

Recovery, stress, strain and sleep are scored against a baseline learned from your own nights and your own sessions. Aera does not compare you to a population. While the history is still thin, it says so instead of guessing.

EVERY WORKOUT, EXPLAINED

Splits, heart rate zones, climb and the ground you covered, with the effort read that says what the session actually cost you. A session with no route gets the same care as one with a map.

YOUR NIGHT, IN ITS OWN SHAPE

The stages of the night as they happened, the hours you slept, and how far that sat from the need Aera learned from you. Sleep debt is carried honestly, never reset to flatter the number.

ON YOUR HOME SCREEN

Your week, your last session, your lifts, your running, your steps, last night and this morning's vitals. Widgets in every size, on the Home Screen and the Lock Screen.

EVERY CLAIM, CITED

66 articles in the Field Guide explain how each read is built, which research it rests on, and where it stops being reliable. No number in Aera is unexplained.
