Live one-to-one coaching

Training only works if people keep showing up.

Gymbile is the all-in-one app that helps your clients stay consistent, so your week goes on coaching, not on chasing new people or payments.

Start free

No monthly fee. You pay only when you're paid.

What I was really paying a trainer for was someone who notices when I stop showing up.

The drop-off

Sound familiar?

The trainers we interviewed reckon 45–60% of their clients are gone within three to six months — especially on quick weight-loss programmes, or after a New Year resolution.

Week 3

Someone goes quiet in week three. Nothing dramatic — a missed session, then a missed week.

Week 6

You don't notice until the bookings stop. By then they've already decided.

After

So you're back to filming, posting and pitching — to replace somebody you already had.

Most coaches read this as a marketing problem and go looking for more clients. But a new client costs far more time, money and energy than the one already in front of you. Gymbile helps you keep them showing up.

I once stopped reminding a client to come. So he stopped coming. Two years later I asked him why, and he said — because you didn't remind me.

How it works

Gymbile is the thing that notices.

It reminds people to keep committing and keeps their motivation up. And it isn't just a calling tool — it's an all-in-one app built so the experience stays seamless for you and for your client.

  1. 1

    It watches for drift

    The missed session. The week gone quiet. The pattern that comes before somebody stops.

  2. 2

    It tells you who, and when

    You see which clients are at risk, while there's still time to do something about it.

  3. 3

    Nudges in one click

    Send a nudge straight to your client, written for you if you'd like, to win them back.

And it remembers who you've already messaged, and tells you when they came back.

All in one app

What's included.

Built with working trainers and nutritionists.

  • One-to-one in the app, on your client's phone. All they need is a connection and a pair of headphones.

    You see them move and correct their form as they go, with the session timer on screen. Clients can also join from a browser, so a flat phone doesn't cost you a session.

  • Answer questions and check meal photos between sessions, so nobody waits a week for feedback.

    Photos, videos, voice notes and files all work, so a client can show you their lunch or a squat they're unsure about. You can send a package offer or a payment request in the same conversation.

  • Clients book your free slots in their own time zone, wherever they are.

    Set your availability once and every client sees it on their own clock. You can also propose a whole run of sessions and let the client accept it in the app.

  • Clients pay in the app when they book, so you never chase an invoice.

    Card payments go through Stripe, straight to your account. There's no monthly fee: the platform fee starts at 15% and drops to 8% as your sessions grow, plus card processing.

  • Drafted from your client's goals and data, and safety-checked before it reaches them.

    Every plan is checked against WPL, our open standard for AI wellness plans, and lays out workouts, nutrition, recovery and habits week by week. Edit any day, then send it on its own or as a package deal. You decide what goes out.

  • Sell blocks of sessions at your own price, open to everyone or made for one client.

    Set the number of sessions, how long they stay valid and the price. Clients see what they save against paying per session, and you can drop an offer straight into a chat.

  • Set the notice periods and late-cancellation terms that fit how you work.

    Build them in tiers, say free up to 24 hours before and a fee after that, and choose whether a package session comes back. Gymbile applies them for you when someone cancels.

  • Clients rate their sessions, and good reviews help new clients choose you.

    Every session can be rated with a score and a comment. Your rating sits on your profile, which is the first thing a new client looks at.

“It's so much easier than fitting around each client and travelling across town.”

FAQ

The things people actually ask.

Something else? Ask our team — a real person answers.

How much does it cost?

Starting is free and there's no monthly fee — you only pay when you train. The platform fee begins at 15% and comes down as your volume grows. The payment system also charges a small processing fee.

If you'd like to hear about the Founding Trainer programme, get in touch.

How will my clients train over a phone? Does it actually work?

It does — we ran one-to-one sessions over a phone for more than a year before we were happy to say so. Your client needs three things: their phone, an internet connection and headphones.

The phone props against almost anything in a gym — a dumbbell, a water bottle. Some people prefer a tripod, but it isn't necessary.

Can I see and message clients?

You can message clients you've already matched with — the ones who came through your invite link or found you in the app. Everyone else can see your profile and start the match themselves.

How do I get more clients?

Being visible comes first, so finish setting up your profile — a half-built one doesn't get seen. Then don't sit and wait: share your invite link actively, and switch on free sessions so people can try you with nothing at stake.

How many clients will I get?

There's no promise that the catalogue alone will fill your week. What tends to work: bring a few existing clients across and ask them for testimonials, price deliberately, and pick one narrow niche and a couple of training types rather than listing everything in the hope of being seen more. Focus on what you're genuinely best at, keep an eye on invites, and reply quickly.

If matches aren't coming at all, our marketing team will give you some free advice.

Do my clients need to download the app?

Yes — they download the free Gymbile client app. No subscription for them, and setting up takes about two minutes.

Is there a video exercise library to build programmes from?

No. You build training and nutrition plans from your client's goals and data using our AI instead. The coaching is still yours — one-to-one, or guided in chat if that's how you prefer to work.

How does Gymbile use AI?

Every plan runs through WPL — our Wellness Plan Language — which checks it for safety before it reaches a client. You're still responsible for the guidance you give, but WPL produces high-quality nutrition and training plans, so you spend less time planning and your clients are less likely to drift.

What if a client messages me and then goes quiet?

Gymbile picks it up and nudges them to come back to the conversation. We won't badger anyone, though — if they decide they don't want to continue, we respect that.

Can I freeze my account?

There's nothing to freeze — Gymbile only charges you when you have active sessions and get paid. Do keep your current clients in mind, though: if anyone's on a subscription or a package deal, give them enough notice to reschedule.

If you're going away for a long stretch, get in touch and we'll match your client with another trainer temporarily rather than let you lose them. They come back to you when you're back.

Something's gone wrong with a client. What do I do?

Get in touch as soon as you can. Our team will look at the situation carefully and come back to you with the options.

I'm not sure what to do next.

Get in touch through support or in the app. Once you register, someone from our team will match with you in the app and answer questions in chat — or on a call, if you'd rather.

Build a practice that doesn't reset every six months.

Five minutes to set up, and nothing to pay until someone books you. You don't have to leave your current platform either — plenty of coaches run both while they try it.
