Coaching software for the Australian coach who actually trains athletes.
One periodised plan builder for AFL, surf, cycling, running and lifting. AI when you want speed, manual when your read of the athlete matters more. Tax invoices in your ABN, not ours. An AI assistant that knows every client.
- ●Get paid in your own name. GST tax invoices, your ABN, zero platform commission.
- ●REPley spots the client who’s about to cancel, 30 days early.
- ●One periodised plan builder. AI for speed, manual builder for control. Both fast.
No feature gates. No add-ons. No commission.
“Most PT software is glorified data storage with a subscription attached. BuildStability is different.”
Vinay Koka · Founder, Synergy Training & Health
“It’s built for PTs first and foremost, not just an app that works for your clients. I’m an actual PT with face-to-face and online clients who switched, and couldn’t be more convinced this is the holy grail.”
Ad Coutts · Ad Coutts Personal Trainer
“The software is amazing! I am only just starting out as a PT but loving it. Building my client base, getting my face out there. As a rent paying PT I was recommended another app that everyone uses by one of the other trainers. Then I found REPley, and I am SO grateful. It is so useable.”

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, two paths in.
Describe the athlete and the season, get an AI plan in 60 seconds. Or open the Build a starting skeleton wizard and shape the day yourself: pick split, goal, equipment, and the day grid arrives pre-shaped with movement-pattern slots that filter the autocomplete by what kit your client has. Both paths end in the same editor. AFL pre-season, surf prep, cycling FTP build, running base, hybrid lifting. 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.
AI nutrition built for Australia.
Australian and NZ government food data plus 49,000 Open Food Facts AU products and our curated Aussie branded list. REPley generates protein, carb, and calorie targets from your athlete’s training block — training day vs rest day macros, no rigid menus. Five logging methods all included: barcode, label photo, meal photo, conversational, voice. The athlete logs in two taps. You see adherence, not raw food logs.
Daily habit coaching between sessions.
REPley drafts up to three tiny habits per athlete from their training block, nutrition targets, and goals, each anchored to an existing routine (after morning coffee, 10-minute walk). The format is straight from published behaviour-change research: anchored if-then plans roughly double follow-through. You approve, the athlete gets a daily Done-or-Skip nudge, and compliance lands next to RPE and attendance. No second habit-tracker app, no admin.
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. Shipped today is shipped today. Next quarter is flagged as next quarter.
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 ten bodies the same plan. BuildStability adapts it per client and leaves every decision with you.
If you can use ChatGPT, you can use BuildStability.
No menus to learn. Ask: build Sarah a 12-week sprint plan. Who’s about to quit? Send last month’s invoices.
Built around them. Not around a template.
Reads their history, RPE, injuries and kit, then writes a periodised plan in 60 seconds. The plan you would write on a quiet Sunday, without the Sunday.
One tap on the floor. Or hand the block to REPley.
Instant moves a barbell by a plate pair, a dumbbell by a kilo, a push-up by reps. REPley reads effort and notes and proposes the next block. Preview everything, undo anything.
AI drafts. You decide.
Every suggestion comes with a reason and waits for your approval. Full version history, so you always see what changed and why.
A program in seconds. Not Sundays.
Describe your client. AI writes a periodised plan from their actual history, not a template. You review, tweak, assign. Resistance programs follow the current research on volume, intensity and progression, and we show our working: how REPley programs resistance training.
- Reads real history
Injury notes, RPE trends, last session’s actual load. Not a generic template, not a population average.
- Edits in-line
No PDF exports. No emailing the plan. No “did you get my program?” The client opens the app, the plan is there.
- Same builder, every sport
HYROX periodisation, healthy-ageing progressions, hybrid lifting, running base. One builder, every sport you coach.
Show them the change. Or watch them drift.
Every client gets a 90-day arc that fills itself in from the workout logger and the calendar. The Transformation page turns it into proof: before/after photos, measurement deltas, strength trends. Clients who can see the change stay, renew, and refer.
- Day 0 in 30 seconds
Goal and starting weight by default. Optional toggles for 1RMs, body measurements, starting photo. Skip what doesn’t matter.
- Six milestones, mostly auto
Day 0, 7, 14, 30, 60, 90. Strength PRs and adherence land on the right milestone automatically. No manual journaling.
- Before/after built in
Photos side by side, measurement deltas, and a silhouette overlay for photo-shy clients. The client-facing polish big-box platforms charge hundreds a month for, on every plan here.
- Day 90 they share
The arc ends with a celebration page the client posts. Warm referrals without asking, and the natural moment to talk about the next 90 days.
Vegemite. Snags. Weet-Bix. In your food database.
Your clients shop at Coles, not USDA. REPley sets protein and calorie targets from the training block. Clients log a Bunnings snag in two taps. No second app. No subscription on top.
- Five ways to log
Barcode, label photo, meal photo, chat with REPley, voice. Every method included on every paid tier.
- Targets, not menus
Macros adjust for training day vs rest day. Clients log what they ate, not what an app prescribed.
- Adherence, not raw logs
Fuel score, protein streak, where the week broke. The view your coaching actually uses.
- Competitors lean on USDA
Their food data is American. Their sync layer is MyFitnessPal. Your client doesn’t shop at USDA.
Smart Habits: coaching the other 165 hours.
REPley drafts up to three tiny daily habits per client, anchored to routines they already have: “after morning coffee, 10-minute walk.” You approve. The app does the chasing.
- Built on published research
Anchored if-then plans roughly double follow-through in exercise studies. New habits take 66 days on average, not 21. Gentle streaks, no broken-streak shaming.
- Drafted, not guessed
Habits come from the client’s program, nutrition targets, and goals. Thin file? REPley asks two quick multiple-choice questions instead of inventing a generic list.
- Not another habit app
No second download, no separate subscription. Habits live beside the program and nutrition in your branded app, and injury flags are respected.
“Set up daily habits for Jess.”
Or build by hand. Faster than you remember.
Some clients you write yourself. Pick split, goal, equipment. The day grid arrives pre-shaped. No blank canvas. No copy-pasting from last week’s Google Doc.
- Skeleton in three picks
Split, goal, equipment. The grid arrives pre-shaped with movement-pattern slots. Push / Pull / Legs in one click.
- Prescription shorthand
3×8 @RPE8 90s parses straight into Sets, Reps, RPE, Rest. One keystroke instead of four dropdowns.
- Auto-saves every two seconds
Section headers (Strength, Accessories, Finisher) appear as you build. Never lose work to a closed tab.
One tap on the floor. Or hand the block to REPley.
Two ways to progress a client, and you pick per client. Both preview before they write. Both undo.
- Instant, and it knows the kit
A barbell moves by a plate pair, a dumbbell by a kilo, a machine by one stack plate. Push-ups and band work climb on reps. Done before your client re-racks the bar.
- Ask REPley when the block needs a rethink
Reads the effort your client reported, your notes and the whole block, then proposes the next one. Linear, undulating or focused phases. About 90 seconds.
- You see every change first
Each row says what moves and why. Overrule any of them, leave any of them, undo the lot. Included on every plan.
Your studio name. Your logo. Your colours.
Your brand in the client experience. Our infrastructure behind it. No email server to run, no app to build.
- Logo and colours, everywhere
Custom logo and primary colour across the client portal, reports, invoices, and check-in screens. One setup, every surface.
- Emails from your name
Bookings, reminders, invoices send from your business name via our infrastructure. No per-studio mail server to wrangle.
- iOS and Android, branded
The BuildStability apps open on your business identity when clients log in. No App Store fees, no developer account.
For the clients the journey did not reach.
A real-time signal across bookings, sessions, and billing that flags drift roughly 30 days early. Save the client before they ghost.
- 30-day early-warning
Reads bookings, logged sessions, billing patterns, and adherence. Flags drift before the client decides to leave.
- Transparent scoring
Every flag shows the why. You see exactly which signals tipped a client into the at-risk bucket. No black box.
- Opt-out per client
Some clients don’t want a score. Switch it off for them. Their data stays yours, never trained on, never sold.
Money shows up. In your account. With a receipt.
Stripe Connect means clients pay you directly. We never touch the money. GST invoices in your business name. Exports your accountant won’t complain about.
- Every billing model
Class packs, memberships, one-offs, direct debit. One system, one dashboard, no juggling between Stripe links and spreadsheets.
- GST done right
Correct invoice whether you’re GST-registered or not. Built by a CPA, not bolted on. BAS-ready exports.
- Zero commission
No per-booking fee. No percentage. Just Stripe’s standard card fee. The price on the page is the price on your bank statement.
Onboarding that runs itself, so you can take on more.
The part of growing you keep putting off now sorts itself. Send one link and the waiver, screening and payment are handled, every client the same way.
- One link, no app
They sign and screen from a phone or browser. Nothing to download, no password, the same for every client.
- Nothing slips through
Flag a condition on the AU and NZ screening and they wait in a review queue. You clear, modify or hold, on the record.
- Money arrives on its own
Near trial end they get a card link, add a card with no login, and billing starts. You never send the awkward text.
A business coach for the business side. Not just another PT app.
Matt Crofts · CPA · 25 Years Software
Every PT tool I tried was old software with a complex price list: tiers, add-ons, and in some cases a cut of what your clients pay you. You should not need a business degree to know whether you are being ripped off. So I built REPley by BuildStability for the AI era of trainers. Ask it in plain English and it runs the admin. Simple to learn, one price with every feature in it, and on your side.
