Numa is one of the most recognizable names in conversational AI for service businesses. Apex Tools AI is the newer, bilingual-first option built specifically for dental practices and med spas. Both can answer your phones. Only one was designed from day one for a med spa where 30% of your callers prefer Spanish, your highest-margin services are booked weeks out, and a missed after-hours call about a $1,200 filler appointment costs more than a month of software.
This is an honest comparison. Where Numa wins, where Apex wins, and the real-world cost math for a single-location med spa doing 800-1,500 calls per month.
The 30-second answer
If you run a single or two-location med spa, serve any meaningful percentage of Spanish-speaking patients, and want flat-rate pricing that doesn't punish you on busy weeks, Apex Tools AI is the better fit. If you run a multi-location service business with deep CRM workflows already wired into a platform like Servgrow or Service Titan, Numa's mature integrations and per-message pricing model may be a closer match — Numa was originally built for trades and restaurants and has spent years polishing those toolchains.
The harder you lean into beauty, wellness, and bilingual patient communication, the more the answer points to Apex.

How they're different at the architecture level
Numa is a horizontal product that has been pulled into healthcare verticals over time. It started as a missed-call recovery tool for restaurants and retail and has grown into a multi-channel AI assistant that handles phone, text, and reviews across many industries. That breadth is real value if you're operating across verticals or already use Numa elsewhere — but it also means the product surface area is huge, the prompts are written to please thousands of business types, and the bilingual handling is more "translation enabled" than "Spanish-first."
Apex Tools AI was built backwards from a different question: what would an AI receptionist look like if it only had to handle dental practices and med spas, and had to nail bilingual EN/ES from the first call? The answer turned out to be a much smaller, much more opinionated product. The AI knows what a "tox appointment" is. It knows how to handle a caller asking about lip filler aftercare in Spanish without machine-translating its way into something awkward. It knows that a prospective client asking about pricing wants a range plus a consult-booking offer, not a brochure.
Neither approach is universally better. They're built for different shapes of business.
Bilingual handling: the honest delta
This is where Apex pulls clearly ahead for the right buyer. Roughly 1 in 8 US adults speaks Spanish at home, and in Florida, Texas, California, Arizona, and parts of New York, that number is much higher. Med spa demand among bilingual and Spanish-preference patients is climbing every year — yet most front desks are English-only.
Numa supports Spanish on certain plans, primarily by routing the caller through translation. It works for short, transactional exchanges. It struggles when a caller code-switches between English and Spanish mid-sentence, when a caller asks a longer aesthetic-treatment question, or when the conversation requires nuance like discussing post-treatment downtime in Spanish without sounding clinical or alarming.
Apex was trained from day one on bilingual conversation patterns specifically for med spa and dental contexts. It handles code-switching naturally, books appointments in either language, and sends confirmation texts in the language the caller spoke. For a med spa in Miami, Houston, San Antonio, or LA, that difference is the difference between converting a Spanish-preference caller and losing them to voicemail.
If your clientele is 95% English-speaking, this advantage doesn't matter much and you can weight other factors more heavily.
Pricing math for a real med spa
Let's run real numbers for a single-location med spa doing 1,200 inbound calls per month. About 600 are existing-client confirmations and quick questions. About 400 are new-prospect inquiries. About 200 are after-hours.
Numa. Plans typically start around $300/mo for basic missed-call recovery and run $500-$700/mo for full AI-assisted answering with bilingual add-ons. Per-message fees on some plans add another $50-$150/mo at this volume. Setup fee varies but expect $0-$1,500. Realistic monthly run rate: $550-$850.
Apex Tools AI. $400/mo flat for the phone tier. No per-call or per-message fees. $2,500 one-time setup. Realistic monthly run rate: $400 — every month, regardless of call volume.
Over a 12-month window, Apex saves $1,800-$5,400 in monthly fees compared to a comparably-equipped Numa plan. The Apex setup fee is higher, but you're typically net-positive within months 3-6 even on the more conservative estimate.
The real win shows up on busy months. A med spa running a Mother's Day or Black Friday promotion might double call volume for two weeks. On a per-message Numa plan, that doubles part of the bill. On Apex, you pay the same $400 you paid in February.
Where Numa wins
Being honest about this matters because Numa is a real product with real strengths.
Multi-location operators. If you run 3+ med spas under one brand, Numa's centralized dashboard, multi-location reporting, and team management features are more polished. Apex is built for single and two-location operators today.
Mature CRM ecosystem. Numa has been integrating with platforms like Mindbody and Booker for longer. The integrations are deeper. If your tech stack is heavily customized around a specific CRM, Numa's connector library is broader than Apex's today.
Brand recognition. Numa has been around longer and has a larger customer base. Some operators value buying from a company with hundreds of public case studies versus a newer specialist.
Non-healthcare verticals. If you also own a restaurant or auto shop alongside your med spa, Numa lets you manage all of it from one platform. Apex doesn't serve those verticals.
Where Apex wins
Bilingual EN/ES. Native, not retrofitted. Detailed above.
Vertical depth. The AI understands aesthetic treatments, dental terminology, pre and post-care language, and HIPAA-aware messaging without needing custom training. You skip the "teach the AI your business" phase.
Flat pricing. $400/mo means $400/mo. No per-call, per-minute, or per-message escalation. You can budget exactly. Promotional spikes don't punish you.
Speed to live. 5 business days from signed contract to live receptionist on your number. Numa setups commonly run 2-3 weeks.
Founder-led service. When something needs adjustment — a new service to add, a price update, a script tweak — you text the founder. No ticket queue. For a smaller operator, this is a real quality-of-life difference.
30-day money-back guarantee. Apex refunds the full setup fee in the first 30 days if it isn't working for you. Numa does not offer a comparable guarantee.
Built-in HIPAA-aware handling. Apex was designed with healthcare conversations in mind from day one — call recordings handled appropriately, PHI not stored where it shouldn't be. Numa is HIPAA-aware on healthcare plans, but it's a layer on top rather than the foundation.
Honest limitations of Apex Tools AI
If we're being fair to Numa, we have to be fair about Apex too.
Newer. Apex has a smaller customer base than Numa. Some operators want to buy from a vendor with a 5-year track record. That's a reasonable preference.
Fewer integrations. Apex covers the most common med spa platforms (Mindbody, Booker, Vagaro, Calendly, Cal.com) but if your stack includes something niche, you'll want to ask before signing. Numa's integration library is broader today.
Not built for 10+ locations. Apex is the right call for solo and 2-location med spas. If you're running a regional chain with shared call queues across 8 locations, Numa's enterprise features are more developed.
No restaurant or trades support. If you also own non-aesthetic businesses, Apex won't serve them.
Decision framework: which one in 60 seconds
Pick Apex Tools AI if:
- You serve any meaningful percentage of Spanish-preference patients
- You're a single or two-location med spa
- You want a flat monthly cost regardless of call volume
- You want to be live in a week, not a month
- You value direct founder access for tweaks and adjustments
- You want a 30-day money-back guarantee on the setup investment
Pick Numa if:
- You operate across multiple verticals (med spa plus other businesses)
- You're a 5+ location regional or national chain
- You're already deeply embedded in a specific CRM where Numa has a mature integration
- You prefer buying from a more established vendor with broader brand recognition
- Your clientele is 95%+ English-speaking and bilingual support isn't a priority
There's no wrong answer. There's a right answer for your specific business.
What makes med spa voice AI different from generic AI
It's worth saying explicitly because most med spa owners are sold "AI receptionist" as a generic category. It isn't. The difference between an AI that's been fine-tuned for med spa conversations and a generic AI is the difference between a receptionist who's worked in your industry for five years and someone you hired off the street last Tuesday.
A med-spa-tuned AI knows that a question about "downtime" is about how long a client will look red after a treatment, not when the office is closed. It knows that "tox" is Botox. It knows that an inquiry about "the new GLP-1 we offer" is a clinical-weight-loss question that should route to a consult, not a back-and-forth chat. It knows what to say when a caller asks if they can come in tomorrow for filler before a wedding on Saturday.
Both Numa and Apex can be configured for med spa work. Apex was built for it. Numa was adapted to it. That gap shows up in transcripts.
How to test before you commit
Whichever platform you're leaning toward, do this before signing:
- Call the demo line and ask three real-world questions a prospective client would ask. ("How much is lip filler?" / "Do you have appointments Saturday?" / "Mi hijo quiere una consulta para acne, ¿cuánto cuesta?")
- Ask about a treatment you offer that's slightly unusual — a peel by name, a specific laser, a package deal — and see how the AI handles it.
- Ask the AI to book you for a consult. Verify the booking actually shows up in your calendar.
- Hang up unexpectedly and call back. Does the AI remember context, or start over?
- Ask the AI to transfer to the owner. See how the handoff works.
A 10-minute test run will tell you more than any sales deck.
The Apex demo line is (954) 475-6922. Call it. Speak Spanish if that's your patient base. Ask the questions you actually get from real callers. If the conversation feels right, book a 15-minute discovery call or text the same number to talk pricing for your specific volume.
If after testing both you're still on the fence, the 30-day money-back guarantee on Apex setup means the decision is largely reversible. Try it for a month. If it isn't right, get the setup fee back and switch.
The thing not to do is keep missing 30-40% of your inbound calls because the receptionist replacement decision feels too big to make. The cost of a missed call to a $1,200 filler appointment is real. The cost of a wrong-fit AI vendor is recoverable. Pick one and start.
