HRV, sleep, load, perception. Reco4U reads your signals and tells you, every morning, what your body can take.
« Rest isn't a pause. It's helping your body get better. »
The noise
- Too many plans.
- Too many sessions.
- Too many sensors.
- Too many injuries.
You follow a program to the letter, but your body doesn't always follow. A bad night, stress, a late meal, a pain, nervous fatigue: anything can change your ability to perform. Reco4U is here to help you see your recovery, understand your signals and optimize your results.
You recover better, you progress faster.
The program is fixed.
The body evolves and changes.
It's the body you have to listen to.
Reco4U analyzes your signals continuously and answers one simple question:
what can your body handle today?
You open the app at wakeup. Reco4U reads your HRV, sleep, load and perception. It returns a CNS score, a muscle map and suggests which muscles are ready to work.
- 01
You listen to your body
Overnight HRV, heart rate, sleep, wrist temperature: Reco4U reads everything your Apple Watch or connected watch records. No extra sensor, no hardware subscription.
- 02
You see what's ready
Track every muscle individually. Green: ready to load. Orange: recovering. Red: protect. You know where to push and where to wait.
- 03
You adapt the load
ACWR, CTL, ATL, TSB: recent load is weighted. Muscles aren't the only thing that counts. The nervous system is essential too.
- 04
Your programs
No fixed program, but you can save your own. You can tell the app which muscles you've worked to track their progression and recovery more easily.
Five screens.
None superfluous.
See your overall recovery.
Composite score computed each morning from six weighted signals: HRV, sleep, resting heart rate, perception, load and temperature. The goal is to analyze your recovery with precision, like a medical or sports team would.
See your muscles and their recovery.
Each muscle group has its own recovery window, adapted to effort and load. You see a body map colored by your real state. Project to +24h, +48h and +72h to plan ahead.
Log the muscles you worked.
At the end of every session, add the muscles you used to track their utilization and recovery state in the muscle page.
Track your progression over time.
This page is built for those who want to analyze their progression with precision. It gathers and analyzes your long-term data: recovery, load, sleep, perception and progression factors. It's more advanced, but stays clear thanks to simple, useful indicators.
