CoachStack

The PT platform built for Australia.

Programs, set-by-set logging, scheduling, messaging and AI-generated workouts. Kilograms and centimetres, Sydney servers, and one price with nothing extra to buy.

What you can do today

No more juggling spreadsheets, group chats, and paper logbooks. CoachStack pulls it all together in one app.

AI program generation

Generate a program in seconds, tuned to a client's goals, equipment, and experience — or build it by hand from a full exercise library.

Set-by-set logging

Log reps, weight, effort level, and RPE 1–10 straight from a phone in the gym as the session happens.

Scheduling & bookings

Run your week from one calendar with availability rules and personal time blocks. Take booking requests without the back-and-forth. Syncs to Google Calendar.

Client messaging

Message clients 1:1 or send broadcasts to your whole roster at once.

Progress & body comp

Track measurements, weight, and training volume over time — with body-fat auto-calculated from Jackson-Pollock 7-site skinfolds. Functional assessments too — sit-to-stand, timed up-and-go, six-minute walk, grip strength.

Guided onboarding

Bring on new clients with a guided wizard and manage every profile, program, and progress view from one place. Includes AUSactive APSS Stage 1 pre-exercise screening and informed consent.

Made for how Australian trainers actually work

From a one-trainer side-hustle to a multi-location studio — CoachStack works on any phone, tablet or desktop, and performs in the gym where it counts.

Fully metric
Kilograms and centimetres everywhere, millimetres only for skinfold calipers.
Local by default
DD/MM/YYYY dates, Australian timezones, and pricing in AUD.
Your clients' data stays in Australia
Hosted in Sydney and built around the Australian Privacy Principles — consent capture, data export and account deletion are in the product, not on a roadmap.
Private per studio
Every studio's data is isolated at the database level. Trainers see their own studio and nothing else.

One price. Everything included.

A$49

per trainer, per month

GST included

  • Unlimited clients
  • Programs, set-by-set logging, scheduling, messaging, progress tracking and studio analytics
  • AI program generation
  • No add-ons, no per-client tiers

Other platforms price by client count and charge extra for payments, branding and nutrition. CoachStack doesn't.

What's coming next

  • Stripe billing — session packs, subscriptions, payouts to your studio
  • Public trainer profile pages with direct booking
  • Push notifications
  • CSV and PDF exports for progress and attendance
  • Progress photos
CoachStack is built on the Sunshine Coast by a working personal trainer who wanted one app instead of a spreadsheet, a group chat and a paper logbook.
