For runners in training

Should you
run today?

Nuta gives you one clear answer every morning — run, easy, or rest — and tells you exactly why, using the data your watch already tracks.

The problem

You have all the data.
You still don't know
what to do with it.

  • 01

    You track HRV, sleep, resting heart rate, mileage — and every morning you're still guessing whether to run or rest.

  • 02

    Your watch says “Body Battery: 44” or “Recovery: 67%.” Your body says “…so?”

  • 03

    You ran hard yesterday and felt fine. This morning your knee is swollen. Nobody saw it coming.

The solution

One answer.
Every morning.

01 · Daily verdict

Run, easy, or rest.

With a plain-English reason. Not another dashboard. Not another score to interpret.

02 · Tomorrow prediction

Reads today. Warns you about tomorrow.

Nuta reads today's effort and flags likely soreness or fatigue 24–48 hours out — before your body tells you.

Rest you can actually trust.

When Nuta says rest, it shows you the proof. Not a warning, not a score — a trade.

“Rest today, and your Thursday tempo will be ~6% faster.”

Why I'm building this
Most mornings I open three apps and a spreadsheet to figure out whether I'm ready to run hard.

I'm training for the SF Marathon in July and the NYC Marathon in November. I'm tired of guessing, and I'm tired of numbers that don't mean anything.

Nuta is the app I want — for me first, then for runners like us.
