Why you lose business on the phone

Your phone rings hardest when nobody can pick it up.

Busy means missed

A caller wants a trial before the January rush. Meanwhile the phone rings out — and the next name on the list picks up.

Every call needs facts

Trial passes, personal training, class bookings — the same questions every time, best asked before the visit, not during it.

Evenings decide

A trial expiring Sunday doesn't wait for opening hours. Whoever answers first gets the booking.

What it handles

The calls your business takes every day

  • Bookings for trial passes, personal training and class bookings into real free slots.
  • Urgency triage by your rules — a trial expiring Sunday goes first.
  • Rescheduling and cancellations, so freed-up slots get filled.
  • Hours, prices and process answered from your own information — never invented.
  • Text confirmations and reminders before the trial.
  • Anything sensitive taken as a proper message and flagged for your team.

What it won't do

Where it stops

  • It doesn't make care decisions — it takes details and escalates to your team.
  • It doesn't pretend to be human; sensitive calls always get a human follow-up.
  • It doesn't pretend to be human.
  • Complaints and sensitive matters become a priority message for your team.

You set these rules during setup, and you can change them any time.

Run your own numbers

What do missed calls cost your business?

Move the sliders to match your business. Nothing here is our claim — it's your estimate, made visible.

Busy line, lunch break, after hours. Your phone system's missed-call log will tell you.

As opposed to a quick question you'd answer later.

Callers who don't leave a voicemail or call back.

Use a typical first appointment. A new customer is usually worth far more over time, but let's be conservative.

Gyms FAQ

Can it book trial passes directly?
Yes — Google Calendar and Microsoft Outlook both work, with the details noted and confirmed by text message. We can build a bespoke integration for your industry software — tell us what you use and we'll say honestly how long it takes.
What happens with an urgent call — a trial expiring Sunday?
The assistant follows your triage rules: it books the nearest suitable slot, collects what your team needs to know, and escalates immediately when you've marked the case as urgent.
What happens when a caller asks for a person?
It can transfer the live call to your staff, or take a message with name, number and reason and mark it for a callback. You choose which topics always go to a human.
How fast does our team hear about urgent calls?
Immediately: the call is flagged as priority with recording and transcript in your dashboard, and notifications go where you configure them.
Which languages does it speak?
Polish and English are in production today, and we've tested real calls in Ukrainian, German, Spanish, Portuguese, Cantonese and Mandarin — ask us about the languages your callers speak.
Do we need to change our phone number?
No. You forward the calls you can't take — busy line, lunch, after hours — to your Synthropia number. We walk you through the forwarding settings.
