Every PT software I tested
stored data and did nothing with it.
So I built one that does. 25 AI tools. One conversation. Your whole business.
You already know your software costs too much. You know about the commissions they take on every client payment, the add-on charges for waivers, and the sales rep who calls every quarter to upsell you a feature that should have been included from the start. You put up with it because the alternative is spreadsheets, and spreadsheets are worse.
I spent 25 years building financial platforms for thousands of Australian businesses. Software where a bad deployment costs real money. You learn to ship things that actually work. After a severe injury meant months of physio and personal training, I saw the other side of it: trainers doing skilled, physical work, stuck running their businesses on tools built to extract revenue from them, not help them.
Meanwhile, apps like Fitbod and JEFIT are offering your clients AI-generated workouts for $10 a month. They don't teach technique, they don't adapt to injuries, and they don't care if someone gets hurt. But they're convenient, and convenience wins when trainers are too busy doing admin to actually coach. The industry doesn't need another scheduling app. It needs AI working for trainers, not against them.
So I built BuildStability. Every feature on every plan. No commissions on your client payments. No premium tier hiding the stuff you need. The pricing is on the website, the roadmap is shaped by the trainers who use it, and there is no sales team because the product should speak for itself.
How we're different
No sales team
If the product can't convince you on its own, that's our problem to fix. Not yours to sit through a demo for.
No commissions
When your client pays you, you get all of it. We charge a flat subscription. That's it.
Every feature, every plan
AI programs, branded client portal, waivers, scheduling, billing. You get it all from day one. We don't hold features back to upsell you later.
Your data stays yours
Open API, structured exports, full access. Your business data works with the tools you already use and the ones you'll use next.
Give me 15 minutes and I'll show you all of it live.
Free. No pitch. Just a walkthrough of how it handles your specific pain points.

The best feedback comes from trainers who use the product every day. We want 10 of them in the room from the start, shaping what gets built next. In exchange, your subscription stays 25% lower than everyone else's. Permanently.
