Your body doesn't move in a straight line. Your recovery app shouldn't either.
What Astrea looks like
Today
One glance, and you know where you stand.
Recovery detail
See exactly what shaped today's recovery score.
Trends & Strain
Ninety days of training load, and where it stands against your own zone.
Sleep detail
One night, broken down stage by stage.
Why we built this
Most recovery apps assume every day should beat the last one. Astrea reads the shape a body actually takes.
If Astrea ever has to choose between reminding you to close a streak or suggesting you go touch some grass instead, it picks the grass. Every time.
Three ways into Astrea
For performance
Know when to push, and when not to.
For the long game
Built for decades, not this week's streak.
For a cycle you already track
See where your cycle stands, next to today's numbers.
