Run your personal training studio from your phone.
Trainerside keeps the schedule, clients, money and payroll in one place, with AI built in. You coach. The app does the paperwork.
Built inside a working gym, not in a software office.
We run Studio Strong, a personal training studio in O'Fallon, Illinois. Our old software was built for a desk. Charges and class prices were edited by hand, and payroll, referral credits, assessments and birthday gifts lived in side spreadsheets.
So we built Trainerside around how our trainers actually work: on a phone, between sessions, with one tap to mark who came and the charges worked out for them.
What it does
Everything a personal training or small-group studio runs on, in one app that installs on your home screen. No app store, no passwords.
Schedule
Day, week and month views with a color per trainer. Repeat sessions weekly or every 2, 3 or 4 weeks. Classes with a capacity, blocked time and time off.
Reconcile in one tap
Attended, no-show, late cancel or cancelled. Charges follow your rules: the late-cancel window, package sessions, each client's rate, or forgive it with a reason.
Clients
Profiles, families, notes and leads. Intake forms filed under each client automatically. Health details stay with owners and trainers.
Packages and money
Packages, sessions left and each client's usual rate. Every charge and payment by month, in a ledger nobody can quietly edit. See who owes and who's in credit.
Payroll
Pay each trainer by percent or a flat rate. Class trainers are paid on the class's income. Free sessions count at a value you set.
Reports
Weekly earnings and what's booked ahead, a cancellations follow-up list, balances, finances and payroll.
Staff and permissions
Owner, trainer and front desk roles, with switches for exactly what each person can see.
Reminders and emails
Session reminders by email and text. Automatic emails when a package runs low or a balance is owed, switched on by you.
Ask, the AI assistant
Type cancel Heidi next Saturday
or I'm off Friday afternoon.
Ask lines up the changes and nothing happens until you confirm.
