01 Built for your day in St. Louis

The headaches we delete from a St. Louis personal trainer's week.

Clients text "what times do you have?" at 10pm and you're juggling a dozen threads to find one open slot.
Your live availability lives online — clients book their own slot 24/7 in seconds, so you stop trading texts and stop losing late-night leads.
A client flakes on a 6am session and you're already at the gym, an empty hour you can't bill.
Take a card on booking and set a cancellation window. No-shows get charged automatically, so flakes drop off and your early mornings actually pay.
Chasing people for cash or Venmo after every session, then forgetting who still owes you.
Sell packages and charge cards up front. Hustl tracks who's paid and what's left, so you train instead of bookkeeping and get paid faster.
~6hours saved every week, back in your pocket

Stop chasing money you've already earned.

Every unpaid invoice is a session you did for free — for now. Send a one-tap payment link, charge the card on file, and let automatic reminders do the awkward follow-up with St. Louis customers for you.

  • One-off invoices & payment links in seconds
  • Card on file — charge the balance the moment you finish
  • Next-day payouts to your bank

"I used to spend an hour a night texting clients about times. Now they book and pay themselves and my no-shows basically stopped because there's a card on file. Easily five hours back a week."
