For PTs, studios, and gyms.
One bill. Every feature. Every plan.
Trainerize launched in 2013. My PT Hub in 2014.
Coaching has changed. Your software hasn’t.
Built for the AI era. Repley runs the admin.
From A$6/mo for solo PTs to A$240/mo for studios with 250+ clients. Your price scales with your business. Your feature list doesn’t.
No feature gates. No add-ons. No commission. AI nutrition built for the Australian shelf.
Clients quit when they stop seeing the change.
“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
Sometimes the data writes the plan. Sometimes you do.
You did not get into training to hand the same plan to ten different bodies. Some clients you write from history. Some you write from what you saw in the room last Tuesday. Both should land in seconds. The work feels like coaching again.
If you can use ChatGPT,
you can use BuildStability.
Most PT software has a tutorial library because every action is a menu you have to find. We replaced the menu with a prompt box. Ask: build Sarah a 12-week sprint plan. Show me who’s about to quit. Send last month’s invoices. Same interface you already know. New career, no learning curve.
Repley reads. You review.
You assign.
Each client’s training history, RPE, injuries, and equipment write the plan. Repley generates a periodised 4-week block in 60 seconds. The plan you would write for them on a quiet Sunday. Without the Sunday. You stay in every decision.
Split, Goal, Equipment.
The day fills in seconds.
Some clients you’d rather build for yourself, in ways the algorithm doesn’t see coming. Pick split → goal → equipment. The day grid arrives pre-shaped to your client’s kit. Type 3×8 @RPE8 90s and the grid fills itself.
You stay in
every decision.
AI plans wait for your review before a client sees them. Manual plans are yours from the first slot. Coaching rules you teach Repley apply to both paths. Every change keeps a version history. Fast, never automatic.
Most fitness software makes money from you. We make money for you to keep.
We do not take a cut of your payments.
No new-client commissions. No slice of your first month’s revenue. A client paying A$200 means A$200 in your account, minus Stripe’s flat card fee. That is it.
We do not charge extra for basics.
Waivers. Branded booking pages. Class packs. Analytics. GST invoices. Automated reminders. Everything is included on every plan.
We do not have a sales team.
No calls. No limited-time offer after you decline. No demo gauntlet to see the price. Read the page, try it, keep it or do not. If you cancel, nobody rings you.
We do not pretend to do your marketing.
Not a funnel builder. Not a content generator. Software that handles bookings, billing, programs, and reminders reliably. Growth is your job. Software is ours.
We do not trap you on cancellation.
One click from Business → Manage Billing. Full data export any time from Settings. 90-day read-only grace period if you change your mind. No retention call. Done means done.
We do not bill in US dollars and pretend.
Built in Australia. Stripe AU. GST invoices that actually say GST. BAS-ready exports. Your bank recognises the merchant. Your accountant does not have to fix anything.
One studio. One month. Same features. Different price.
That is a silent partner on the P&L. The higher tier, or a second location, multiplies it fast.

Enterprise pricing sourced from public quotes (StudioStackTools, CheckThat.ai, Pabau; Feb–Mar 2026). Actual contracts are sales-quoted by the vendor and vary by location count, volume, and negotiated rates. Payment processing fees are comparable across platforms and excluded from the subscription comparison. Full methodology →
Clients book themselves.
1-on-1s, classes, walk-ins. They book, you approve. Built for trainers, studios, and gyms.
- Every session type
1-on-1s, group classes, and gym sessions. Clients book themselves, you approve.
- Capacity and waitlist
Class capacity with waitlist auto-promotion. A spot opens, the next client gets it.
- AI times, voice reschedule
AI suggests times from your patterns. Reschedule a whole day in one sentence.
Onboard every client the same way, in the gym or online.
Build the recipe once. Every new client gets the waiver, health screening, first plan, and trial the moment they accept.
- One recipe per coaching type
In person, online or self-guided. Each carries its own waiver, screening, first plan, membership and trial length.
- One link, no app
Clients finish the waiver and screening from a phone or browser, no password. Anyone who flags a condition lands in your review queue. Screening for AU and NZ.
- The trial collects its own payment
Near trial end the client gets a card link, adds a card, the subscription starts. You never send the awkward pay message.
Your studio name, your logo, your colours.
Your brand up front. Our infrastructure behind it. No email server, 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.
A program in seconds. Not Sundays.
Tell it: “Sarah, shoulder impingement, 3x/week, 4-week hypertrophy.” AI writes the periodised plan from her history, not a population average. You review, tweak, assign.
- 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.
“Build a 4-week hypertrophy program for Sarah. Shoulder impingement, 3x/week.”
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 extra subscription.
- 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.
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 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.
Show them the change. Or watch them drift.
Every client gets a 90-day arc. Day 0 takes 30 seconds. Days 7, 14, 30, 60, and 90 fill themselves in. Day 90 is a page they share.
- Day 0 in 30 seconds
Goal and starting weight by default. Optional toggles for 1RMs, body measurements, starting photo. Skip what doesn’t matter.
- Milestones auto-fill
Strength PRs from the logger and adherence from the calendar land on the right milestone automatically. No manual journaling.
- Day 90 they share
The arc ends with a celebration page the client posts. Referrals follow without you asking.
For the clients the journey did not reach.
A live signal across bookings, sessions, and billing flags drift 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: clients pay you directly. We never touch the money. GST invoices in your business name. CSV 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.
We did not invent the problem. We hear it every week from trainers switching to us.
Four patterns, unattributed, because the point is the pattern, not the brand. If any of these sound familiar, it is not just you.
Commissions on every new client.
A common pattern across the category: platforms take a percentage of a new client’s first payment, capped but still meaningful at scale. For a studio signing 3 new clients a month, that is often more than the subscription itself.
Zero commission. Flat monthly. Every feature included.
Cancellation that requires a phone call.
Trainers across the industry report needing to call support or sit through retention flows to stop a subscription. Payments can continue during the back-and-forth.
One click from Business → Manage Billing. Full data export any time. No retention call.
Features you already pay for, sold again.
Waivers, automated emails, studio branding, analytics. Commonly bolted on as paid add-ons. By the time a small studio has what it actually needs, the monthly bill rivals its rent.
One tier structure, one price per tier. Every feature ships on every plan. Waivers, class packs, analytics, automated reminders, client portal branding. Included at A$6/mo through A$240/mo.
Software that does not understand GST.
Most global platforms treat Australian GST as an edge case. Trainers end up manually fixing the invoice their own software generates.
Built by a CPA. GST-correct invoices. BAS-ready exports. The minimum, not a feature.
See it work in two minutes.
Not a sales call. Not a gated form. A 2-minute walkthrough of the parts of the product trainers spend the most time in.
One thing we care about more than feature parity.
We never want to see you go. Life changes, and we hope it's that, not that the product let you down. Either way, cancellation isn't a fight. The PT software category has a cancellation problem. We do the opposite, on the record.
Cancel in 1 click. Directly from the Business page. No support ticket. No phone call.
Keep access until the end of your billing period. No immediate lockouts. Export your data on your schedule.
Changed your mind? Undo in 1 click. Reverse a pending cancellation any time before it takes effect.
What small studios ask before they actually switch.
You are new. Why should I trust you with my business?
Three reasons. The founder has 25 years running software in industries where a bad deployment costs someone’s mortgage: banking, accounting, early fintech AI. We use Stripe Connect, so your money never touches our account. It flows direct to your bank. And at any time you can export everything and leave. If we ever lose your trust, we make it easy to walk, not hard.
How can BuildStability charge A$6 a month when competitors charge A$200+?
No sales team. No paid ads at the scale the big global players run. Every feature ships on every plan, so there is no pricing tier to build an upsell team around. The product was built because the founder needed it. The price is what it needs to be to keep the lights on and serve 10,000 quiet, happy studios.
Will my clients have to download another app?
Only if you want them to. The booking and payment flow lives on a link clients can save to their home screen. BuildStability has iOS and Android apps for studios that want them, carrying your branding. No download is required to pay or book.
I am on Mindbody, Trainerize, or TrueCoach. Is migration painful?
It is not fun, but we do it. Founding Member trainers get migration done for them: client list, active subscriptions, program templates, class packs. Export your data from the old platform, send it to us, and we rebuild it on BuildStability. Usually takes under a week.
What does the AI actually do?
Three things. It drafts a periodised program from a client’s actual history and your prompt. It generates nutrition targets (protein, carbs, calories) from that client’s training block and lets them log meals via barcode, photo, or chat. And it scores engagement to flag clients at risk of leaving. You always edit before assigning. The AI does not auto-message clients. It does not rewrite your notes. It does not write meal menus. It does not replace your coaching. The AI does admin. You coach.
Does BuildStability work in Australia and New Zealand?
Yes. Built in Australia, with first-class support for New Zealand. AU trainers bill clients in AUD with GST tax invoices and your ABN. NZ trainers set their business currency to NZD, charge clients in NZD through their own Stripe account, and get tax invoices with 15% GST and their IRD number. Both get BAS-ready or GST-ready CSV exports and local timezone scheduling with daylight saving handled correctly. Your own BuildStability subscription is billed in NZD too.
