How it works

1

Tell Liv your goal

A marathon. Easing PMS. Building fitness. More energy day to day.

2

Liv builds your plan

Trained on the research. Tuned to your cycle.

3

Adjust as you go

She listens to your check-ins and changes what isn't working.

Cycle Tracking

You're not the same person every week.

Your cycle has four phases. Each one changes how you train, eat, sleep, and recover. HerRhythm meets you in whichever one you're in today.

Weekly Recommendations

Built for what you're working towards. Tuned to where you are.

Booked a marathon for five months' time? Liv builds your training week by week, based on your cycle and symptoms, so you do your best on the day. Just trying to regulate PMS? She shapes your training, nutrition, and recovery to soften the symptoms. Whatever you're aiming at, she maps the path.

Liv's Brain

See what informs every recommendation.

Most apps tell you what to do. HerRhythm shows you why. Every claim Liv makes is traceable to peer-reviewed research, graded by how strong the evidence is, and flagged where the gaps remain.

Daily Log

When the reliable evidence falls short, Liv listens to you.

Most exercise research is done on men. Most cycle research studies a narrow slice of women. Liv knows where the science is sturdy, where it's shaky, and where there's nothing at all. Thirty seconds a day teaches her how to coach you better.
