Adherence is the programme. Now you can coach it.

The plan was never the problem. Tuesday night was. GrowthArc puts your programme on the client’s phone and wrist, asks for the weigh-in, the photo and the two-tap check-in on schedule, and lets you nudge the forty people on your roster with your face, not a spreadsheet. Priced per coach, never per client.

No card to start. Every plan takes 0% of what you earn.

One client, one week, forty times over

The phone is Leo’s, twelve weeks into a fat-loss block. Everything here happens without a message from you, until the one that matters.

Thursday 7:10 pm · Today

The programme as three rows, not a PDF

Your block, broken into daily behaviours with cues and tiny versions. Protein and steps ticked from the wrist during the day; the sleep habit due tonight. The arc shows the week, not a wall of red.

10:55 pm · Check-in

Adherence, without a food diary

How hard was it, what got in the way. “Late shift” and “screens” on the sleep habit, three Thursdays running, is the pattern that fixes his recovery, and it took two taps to capture.

Monday 6:30 am · Reading

The weigh-in asks for itself

Weight on Mondays, waist on the first, a progress photo every fortnight, requested on schedule and charted as a trend. The photo hands off to the phone camera from the watch in one press.

Tuesday 7:15 pm · Companion

Your nutrition philosophy, at the restaurant table

The companion answers in your approach: protein first, no anxiety. It knows your uploaded guides, it answers in his language, and it hands you anything medical with the thread.

Friday 6:45 am · Nudge

Forty clients, one morning, your voice

The assistant drafted touches for the three clients whose week said something. You approved them in the queue with your coffee. Each one lands with your face and one button.

Sunday · Milestone

Fourteen for fourteen, on the wrist

The ring closes on the watch mid-cooldown. The assistant drafts your “say something”. Compliance you used to chase in DMs is now a habit he is proud of.

Deep use cases

Four ways fitness coaches actually run

Online rosters, sold programmes, nutrition adherence and the in-person client between sessions. The tabs turn on their own; tap one to stay.

Forty online clients without forty spreadsheets

The situation

Weekly check-in forms in one tool, photos in a chat app, weigh-ins in a spreadsheet, and Sunday night spent working out who is quietly drifting.

What GrowthArc does

Every client’s habits, readings and photos land in one profile. Health scores rank the roster by who is slipping; the attention board opens on them. Weekly check-ins are two taps on the client’s phone, not a form they abandon. Sunday night becomes ten minutes of approving drafted nudges.

Fits Pro · unlimited clients, readings on scheduleStart free

The transformation programme you sell from your bio

The situation

A 12-week block people ask about every day. Selling it means a checkout tool, a delivery tool, a chat group and a fee on every sale.

What GrowthArc does

Build the block once in the Journey Studio, publish the offer page with checkout, put the link in your bio. Buyers land in the app with your face on the welcome and the first week scheduled. You keep 100% of the price; Stripe passes through at cost.

Fits Pro · payments, invoicing and payoutsStart free

Nutrition coaching that does not need a food diary

The situation

Food logging fails by week three for almost everyone. What you actually need is whether the three behaviours you agreed happened, and what got in the way when they did not.

What GrowthArc does

Protein at breakfast, vegetables at two meals, no eating after nine: three habits with two-tap check-ins. Obstacles surface as patterns (“work lunch”, “kids’ leftovers”) and the companion answers the restaurant question in your philosophy at 7pm on a Tuesday.

Fits Solo · for a part-time nutrition practiceStart free

Personal training, extended to the other 166 hours

The situation

Two sessions a week are perfect. The other 166 hours decide the result, and right now they belong to nobody.

What GrowthArc does

Steps, protein and sleep as wrist taps; a nudge with your face the evening before a session; the weigh-in on Monday so the session opens with data instead of “how was your week?”. Your calendar and Zoom links sync both ways for the remote weeks.

The roster, ranked by who needs you

Health scores move with completions, check-ins, sessions and messages, so the dashboard opens on the two people who are slipping and the one hitting a milestone tonight, not on a table of everyone. The assistant has already drafted the touches; you approve, edit or skip.

8:03 am · Client

A whole fortnight on one screen

Every completion, every reading, every check-in word Leo typed at 9pm. The pattern that took you three sessions to notice is a chart now, and the assistant has put the sentence under it.

1:55 pm · Session

The brief is written before you sit down

What moved, what stalled, their own words from the week, and the thread the assistant suggests you pull. Two minutes of reading replaces fifteen of prep. On Scale, every session gets one automatically.

How the assistant works →
Once · Settings

Set the rule, then stop remembering it

Three quiet days drafts a nudge in your voice. A milestone drafts a celebration. A new client gets your welcome sequence. Rules run every morning; nothing sends without your tap unless you say so.

The behavioural loop

Four things, in a circle, every day

Check-in, reading, nudge, milestone. For a fitness client the loop is protein, steps and sleep on a wrist, a Monday weigh-in, and your face on Friday morning. Adherence stops being a lecture and becomes a streak.

Questions

From fitness and nutrition coaches

Do I pay per client like the other platforms?
No. Every plan is per coach. Solo includes 20 active clients; Pro and above are unlimited. A roster of 60 costs the same as a roster of 25.
Can clients log from the gym without their phone?
Yes. The Apple Watch companion ticks habits and logs readings in two seconds; out of range, taps queue and reconcile when the phone is back.
Does it do workout programming?
GrowthArc runs adherence and coaching between sessions: habits, readings, photos, check-ins, nudges, payments. Bring your programming from wherever you write it; the behaviours that make it work live here.
Can I import my existing programme content?
Paste a YouTube, TikTok or Instagram link, or upload a document, and the Studio drafts a journey with phases, habits and check-ins for your edit.
