Now onboarding gyms across Arizona and Texas.

Show your members what the scale can’t

Half of new members are gone within six months, and most of them did not fail. They trained, the scale barely moved, and nothing told them it was working. Rysflo gives them a reading every morning — and gives your gym a reason they stay.

Four things your gym cannot measure today

Each of these is a measurement gap rather than an effort gap. Your members are working; nobody can see what is happening.

TodayWith Rysflo
Progress

The scale

Weight moves slowly, and it never says why. A member can be doing everything right and still see nothing for weeks.

Acetone

How much fat the body is using for energy, read every morning rather than inferred a fortnight later.

Plate

Food diaries

Self-reported and impossible to check, even when the member is reporting in good faith.

Hydrogen

How much the gut is fermenting, which shows what was absorbed and what was not.

Processing

Guesswork

No way to tell how a meal actually landed for that particular member.

Ethanol

How much sugar from meals is fermenting, against that member’s own baseline.

Persistence

Surfaces at cancellation

A member who has stopped coming has usually already decided.

Surfaces in the app

A reading that stops is the earliest churn signal there is, and it appears weeks before the cancellation does.

A metabolism tracker for everyday gym members

Sixty seconds each morning, fasted, on their own phone. Built for regular members, not elite athletes.

Breathes in, holds, breathes out

A minute before coffee. No lab, no appointment, no trip to the front desk.

Reads three markers

Acetone, hydrogen and ethanol combine into one morning score, read against that member’s own baseline.

The appA member and a trainer looking at the day's plan on a phone

Turns it into the day’s food

Macros from their own numbers, a weekly plan with a recipe for every meal, any brand they buy. Swap a meal whenever they like.

Over six weeksA member reviewing a six-week trend with their trainer

Shows the direction

One reading is a snapshot. Six weeks of readings, alongside their weigh-ins, show whether they are heading the right way.

Rysflo is a wellness tracker. Markers reflect trends over days, and it does not diagnose anything.

What you see in your dashboard

Five views of every member, from the same morning reading. You are the admin: add your trainers, set what they see, and keep every member in one place.

Test Analysis in the Rysflo gym dashboard

One score, three gases

A composite out of 100 with its zone, broken into acetone, hydrogen and ethanol. Every reading carries two explanations — a plain one and the underlying science — so your team can pitch it at whatever level the member wants.

Sixty seconds of your member’s morning

Taken at home, before they leave the house. Nothing for your front desk to run, nothing for your team to chase.

Set up my gym

20% of every membership, every month

Paid to the gym for as long as the member stays active, on a $29 membership. No stock to buy, no minimum, nothing to front.

$87a month with 15 members on Rysflo
$174a month with 30 members
$290a month with 50 members

The 20% is not the point. The members who stay are worth more to you than the commission. Every extra month a member keeps coming is revenue you were going to lose.

What your gym gets

A reason to stay

A member who can see something changing has a reason to keep coming. Retention first; the commission is the smaller half of this.

Something to offer

Few gyms offer metabolic tracking. It gives you something to talk about that the gym down the road cannot.

New income, zero cost

No hardware to buy, no shelf space, no staff time. Members pay Rysflo directly and you are paid every month.

Full control

You are the admin. Add your trainers, share your cut with them if you choose, and see every member in one dashboard.

Your trainers bring the members

Optional, and entirely your call — set each trainer’s share in your dashboard, from nothing to all of it.

Share your 20%, or don’t

Give a trainer a cut of the members they bring in. You set the split per trainer, and you can change it whenever you like.

Clients between sessions

Trends and food logs every day, not only on session days. Something to open the next session with.

Clients who stay

A client who can see progress stays engaged, and stays with their trainer. That is your retention too.

A reason to talk about it

If you choose to share, your trainers have a reason to mention Rysflo every day, without you having to run a campaign.
