Sound Familiar?

You train 6 clients today at three different locations. Your 7am client bought a 10-pack and you think this is session 8 but you're not sure. Your 9am wants to switch from in-person to virtual this week. Your noon client's package expired and you need to invoice for renewal, but you're between sessions in a parking lot. Mindbody charges you $139/month for features designed for yoga studios with 30 employees.

Why Personal Trainers Are Fed Up

"$139/month base and it's built for yoga studios and big gyms. Solo trainers get the same bloated software at almost the same price."
— Common personal trainer complaint about Mindbody
"Even more basic than Acuity. Can't manage packages, can't take payments properly, can't track anything a trainer needs."
— Common personal trainer complaint about Calendly

Why One App Beats Three Subscriptions

Most personal trainers cobble together 3-5 separate apps — one for scheduling, one for invoicing, one for bookkeeping, maybe another for client management. Each one charges monthly. None of them talk to each other. So you end up copying client info between apps, manually reconciling invoices with your books, and losing track of details that fall through the cracks.

Helix takes a different approach. All 11 modules share one data source. Finish a job → invoice auto-generates. Track time → it feeds your billing. A client books online → their info appears in your CRM. No Zapier. No CSV exports. No "did I update that in the other app?" $279 once — or $99 today and two more payments — and you own the entire integrated system. 30-day money-back guarantee.
