How it works
Three steps. No guesswork.
/ 01
Wear it
A light band reads your heart all day and night — no buttons, no check-ins, no charging anxiety.
/ 02
Read your recovery
Every morning one score tells you whether to push or rest, built from HRV and resting heart rate.
/ 03
Train smarter
Zones, load, and strain in plain words — so you stop guessing and start recovering.
02
Everything but the guesswork
Read more, doubt less.
HRV, every morning
Heart-rate variability read the moment you wake, before coffee ruins the number.
Sleep scored
Deep, REM, and light, weighted into a nightly score you can actually use.
Readiness score
One number that says push today or take it easy. No guilt either way.
Training zones
Five zones tuned to your real threshold, not an age formula.
Load & strain
How much your last week cost, and whether you're building or breaking.
Recovery community
Groups, challenges, and coaches who read your data with you.
03
The honest number
Shot where the work actually happens.
04
Your night, live
Recovery isn't a mood. It's a signal.
Heart-rate variability, resting heart rate, and oxygen saturation — the three numbers that tell you whether today is a push day or a rest day.

From the desk of Jonah Reyes
Your body already knows. We're just reading it out loud.
I started pulse after a coach told me to "listen to my body" and my body, it turns out, only spoke in symptoms — the injury, the bad night, the week I couldn't hit a single split.
What I learned: the body talks constantly, in numbers. HRV dips before you get sick. Resting heart rate climbs before you're overtrained. Sleep stages tell you what the hours actually did. You just need someone to read it.
So here's the promise: one score every morning, honest as a pulse. Push when it says push, rest when it says rest, and stop guessing at a body you live in every day.

Questions, answered.
What does pulse actually measure?+
Heart rate, HRV, resting heart rate, and sleep stages — read from a light band worn day and night.
Is it just another fitness watch?+
No. Most trackers count steps and show you a number. Pulse reads recovery and tells you what to do with it.
Do I need to wear it 24/7?+
Night is non-negotiable — that's where recovery happens. Days are optional but recommended.
Is it free?+
Yes — the core recovery read is free during beta and stays free after launch.
Does it share my health data?+
Never without your say-so. Your vitals are yours, encrypted, and never sold.
Can my coach see my data?+
Only if you invite them. Coach mode is read-only and you can revoke it anytime.
Your body is already talking.
