Built for the Australian coach who actually trains athletes.
Every feature included on every plan. No per-client fees, no per-feature add-ons, no commission on what your athletes pay you. Cancel any time.
One periodised plan builder.
Many sports. AFL pre-season, surf prep, cycling FTP build, running base, hybrid lifting. Free-text sport context: describe the athlete and the season, get a plan in 60 seconds. Stop running TrainingPeaks and Trainerize and a spreadsheet for one roster.
Per-client adaptation, visible.
Edit a template, push to forty active clients. The engine defers it for clients in deload, swaps lifts they don’t have, skips clients with relevant injuries. You see every change before it goes out. Forty conversations you didn’t have to have.
Tax invoices in your ABN, not ours.
Stripe Connect direct payouts to your bank, zero platform commission, GST line items every time. Most global coaching tools collect on their own merchant account and put their name on the receipt. We don’t.
Repley, the AI assistant that knows your roster.
Ask "who’s about to cancel?", "what’s Sarah’s deadlift trending toward?", "show me my Q3 GST report". Built on a 25+ tool registry across scheduling, programs, billing and engagement. No competitor has this; most have a workout-only chatbot or none at all.
Predicts churn 30 days early.
Engagement Score blends frequency, RPE drift, missed sessions and billing signals into a forward-looking risk score. Save the client before they ghost. Most competitors show last-30-day engagement. We show next-30-day risk.
Strava sync today.
Garmin and Apple Health on the way. Their runs, rides and structured sessions land on the client profile automatically. Multi-tracker support is on the near roadmap; we’re honest about what’s shipped versus what’s next.
90-day onboarding journey, automated.
Six milestones (days 0, 7, 14, 30, 60, 90), auto-tracked from logged sessions and PRs. Day 90 ends with a shareable celebration page the client posts. Retention by design, not by reminder texts.
Self-serve booking your clients can run.
Optional approval gate when you want control. No SMS back-and-forth, no double bookings, no calendar tetris.
Most software hands you a template. We hand you a coach that scales.
You did not get into training to hand the same plan to ten different bodies. Most software makes you do it anyway. BuildStability adapts the template per client. You stay in every decision. The work feels like coaching again.
Built around them. Not around a template.
Reads each client’s training history, RPE trends, injury notes, and equipment, then writes a periodised plan in 60 seconds. The plan you would write for them on a quiet Sunday. Without the Sunday.
Edit the program. Forty plans update themselves.
Push a template change to your active client list. The engine defers it for clients in deload, swaps the lift if their gym does not have it, skips clients with relevant injuries, applies the rest. Forty individual conversations you did not have to have. Forty clients who feel like the plan was written for them. Because it was.
The AI types. You coach.
Every progression suggestion comes with a reason. Every change waits for your approval. Full version history, so you can always see what the plan was, what it became, and why. The line between “fast” and “automatic” stays where you draw it.
A program in seconds. Not Sundays.
Describe your client and the AI writes a periodised plan from their actual history, not a template. You review, tweak, assign. Finish your coffee.
- Uses injury notes, RPE trends, and last session’s actual load.
- Edits in-line. No PDF exports, no “did you get my program?”
- Same builder runs HYROX periodisation and healthy-ageing programs.
Edit the program. Forty plans update themselves.
Most software gives you copy-paste. We adapt per client. Push a template change to your active list and the engine defers it for clients in deload, swaps lifts when the gym doesn’t have the kit, and pauses on flagged injury notes, then applies the rest. That’s hours back for the coaching that actually moves the needle.
- Two-step review. Expand any client to see what lands for them and Repley’s reasoning.
- Reads RPE trends, injury notes, and current block on every client before adapting.
Show them the change. Or watch them drift.
Every client gets a 90-day arc. Day 0 takes 30 seconds. Day 7, 14, 30, 60, and 90 fill themselves in from the workout logger and the calendar. Day 90 is a page they share.
- Day 0, 7, 14, 30, 60, 90. Six milestones, mostly auto.
- Strength PRs and adherence land on milestones automatically.
- Day 90 ends with a shareable celebration page. Referrals follow.
For the clients the journey did not reach.
The 90-day journey keeps most clients engaged. Engagement Score is the safety net: a real-time signal across bookings, logged sessions, and billing that flags drift roughly 30 days early.
- Detection layer beneath the journey, not a duplicate of it.
- Scoring is transparent. You see why a client is flagged.
- Opt-out for any client. Data stays yours, always.
Money shows up. In your account. With a receipt.
Stripe Connect means clients pay you directly. BuildStability never touches the money. We send the GST invoice in your business name and keep an export your accountant will not complain about.
- Class packs, memberships, one-offs, direct debit. All in.
- GST-registered or not. Correct invoice either way.
- No per-booking fee. No percentage. Just Stripe’s card fee.
Your studio name. Your logo. Your colours.
Client portal, reports, invoices, and app check-in all carry your studio identity. Emails send from your business name via our infrastructure.
- Custom logo and primary colour across portal, reports, invoices.
- Emails carry your business name. No setup, no email server to run.
- The BuildStability iOS and Android apps open on your identity.
Your clients already use AI to train. You should too.

Apps like Fitbod and JEFIT sell your clients AI workouts for $10/month. Every PT tool I tried just stored data and charged for it. So I built one that fights back. AI that works for trainers. Not against them.
