What's your Discipline?

Discipline

Stop paying to grow

White-label apps make growth expensive. Trainerize, Everfit, TrueCoach: the more you grow, the more they charge

Revenue cut on every subscription.
No ownership or asset value, unable to sell your platform.
Your audience locked behind their login.
No control over UX, workout plans or features.
Every competitor on the same template.
Updates ship on their schedule, not yours.

Build the asset, not just the income

Chris Hemsworth sold Centr in a $200 million deal. Kayla Itsines sold Sweat in a deal reported at $400 million. MyFitnessPal sold to Under Armour for $475 million. Smaller niche apps in cycling, running, yoga, and strength get acquired every year, quietly, in the seven and eight figures. But none of it happens unless you own the code.

Most coaches stall at step three

You built the skill icon
01

You built the skill

Years of training clients, refining your method, learning what actually works. The expertise is real. Nobody can take that.

You built the audience icon
02

You built the audience

Followers, subscribers, DMs, comments. People who watch your content because they trust your voice. The audience is real too.

You hit the wall icon
03

You hit the wall

This is where most coaches stop. In-person training is limited to the hours in your day. Online 1-on-1 caps out around 30 clients. Your audience grows. Your income doesn't.

How I got back on track with sport in my late 30's

Simon Klobas

Simon Klobas

Founder

Hi, I'm Simon, and this is why I built FitDev.


I'm a surfer, sailor and software developer. Sport has always been a huge part of my life.


But three years ago, I couldn't paddle out into the surf. I had hectic neck and shoulder pain and I was really unfit. On top of that I was about to move from Sydney to New York City and was scared shitless it would kill my surfing dream and fitness entirely.


Then I found a surf coach online who had built an app specifically for surfers. Not generic workouts. Not "fitness." Surfing-specific programming from someone who understood the sport.


That program changed everything. Within months, I was back in the water and surfing at a higher level than ever before — just because I was doing the right kind of training. Now I'm hitting the gym 5-6 days a week doing tailored exercises and I can't imagine training any other way.


Turns out generic fitness wasn't going to cut it. What I actually needed was someone who understood surfing, building programs for surfers, in an app I could check anytime.


Every coach has this ability. Every fitness professional has the expertise to build what I found. But most of them are stuck with no platform to deliver it — or they're using generic, expensive white-labelled platforms that don't let them build for their niche.


They're forced to give generic workouts instead of sport-specific coaching, and they're paying platforms a cut of every sale. They're building someone else's business.


I looked at Kayla Itsines and her SWEAT app and Chris Hemsworth's CENTR app and the huge success they had, and I thought: more people could do this if they had my software skills, or if I had their coaching skills.


So I built FitDev to bridge that gap — and to help trainers build their own businesses.


If you have an audience and you understand your sport better than anyone else, you should be able to ship an app that reflects that expertise. You should own it. You should keep the revenue. And your clients should get coaching tailored to their sport — not a templated program from a third party company.


That's what FitDev does. It gives you the codebase and the guidance to launch your own app in 30 days — so you can do for your audience what my surf coach did for me.


Yew.


Cheers, Simon

FAQ

Common questions about the program, the codebase, and what you'll own

Join the waitlist
No. Joining the waitlist is free. It locks in your launch price. Everyone after launch pays $1,999.
Nothing to us. We don't charge licensing fees, subscription fees, or take a platform cut. Standard third-party costs apply (Apple Developer account, Stripe processing, hosting, AI usage if you enable it) — same as any business running its own software.
We will show you how to connect your own Stripe account so you can directly collect revenue from your clients with no intermediary.
No. The Program walks you through every step in plain English. You'll customize the app through simple configuration files, brand it with your colors and logo, and submit to the App Store using a guided checklist. If you can follow a recipe, you can launch this app.
No. It's a one-time payment. You own your app forever. No subscription, no per-client fees, no revenue share, no platform tax.
About 30 days if you dedicate time and stick to the standard customization path. Heavy customization (deep design changes, building new features beyond the included ones) extends the timeline. Most coaches who follow the Program ship within four to six weeks.
Yes. Do it yourself, hire a developer, or prompt an AI. The codebase is yours to extend however you want. Add new features, redesign screens, integrate new services. There's no roadmap you're waiting on, and no permission you need to ask for.
