Trainerize vs Everfit vs Custom: What Coaches Should Actually Build

We build custom coaching apps for a living, so read what follows with that in mind — and then notice that most of it argues against hiring us. That's deliberate. The single most common way coaches waste money in this category is by commissioning a custom platform two years before they needed one, and we'd rather be the studio that told you to wait than the one that took the cheque.

This is a comparison of three options: Trainerize, Everfit, and building your own. It includes the arithmetic that decides between them, the thresholds where the answer flips, and the middle path that most coaches asking this question should actually take.

First: what problem are you actually solving?

Before comparing anything, get specific about the complaint. In our experience the coaches searching for Trainerize alternatives fall into five groups, and only one of them should be reading a comparison table.

1. "The app feels generic and my brand is my business." This is a real feeling and almost never worth a platform migration, let alone a build.
2. "I'm paying too much per client." Legitimate. There's math below, and the answer will surprise you.
3. "It can't do the specific thing my method depends on." The best reason on this list, if the thing is genuinely load-bearing.
4. "My team is doing hours of manual work the platform won't automate." Also legitimate, and usually fixable without leaving.
5. "I want to sell my system to other coaches." You're not choosing a coaching platform. You're becoming a software company. Different article, different budget.

Hold your answer. It determines which section below matters.

The two platforms, honestly

Both Trainerize and Everfit are mature products built by teams who understand coaching. Neither is bad. They differ in emphasis, and the emphasis is what should decide it.

Trainerize

Trainerize — now ABC Trainerize, part of ABC Fitness — is the incumbent. It has been in the market a long time and that shows in the breadth: a very large exercise library with demonstration video, program and workout building, in-app messaging, habit and goal tracking, progress photos and measurements, integrated payments, nutrition tracking through MyFitnessPal integration, and connections to the mainstream wearable and health platforms.

Its real advantage is ubiquity. Clients have often used it before. Other coaches you hire have used it. There's a large body of tutorials, templates and community knowledge. If you're an in-person trainer moving clients online, or a gym adding a remote offering, that ubiquity has genuine operational value.

Its usual complaint is that breadth-first products accumulate surface area, and the interface reflects a decade of accumulated features.

Everfit

Everfit is the newer product and it's built around automation. Where Trainerize is strongest at giving one coach good tools, Everfit is strongest at letting a coaching business run programs at scale without a human touching every step: automated program sequences that deliver on a schedule, task and habit automation, forms and questionnaires wired into workflows, and team structures for businesses with multiple coaches and an ops person.

If your business looks like "a template protocol delivered to many clients with periodic personalization," Everfit's architecture matches that shape more naturally.

Its usual complaint is a smaller ecosystem and, being newer, fewer clients who already know it.

The others worth looking at

If you're genuinely shopping, the category is wider than two: TrueCoach, PT Distinction, My PT Hub, Exercise.com, Kahunas and Hevy Coach all serve overlapping audiences with different emphases — some lighter and cheaper, some closer to a gym platform, some built around a specific coaching philosophy. A trial week in three of them will teach you more than any comparison article, this one included.

What we will not do

We're not going to publish a price table for either product. Both price in tiers by active client count, both change their tiers, both have promotional and annual rates, and both sell a custom-branded app as a paid add-on. Any number we print here would be wrong within a quarter and you'd budget against it. Get current pricing from their own sites, for your actual client count, including the branded-app add-on if you want one. Then come back for the math.

The arithmetic that decides it

Here's the structural fact that makes the comparison possible without knowing their prices: coaching platforms charge by active client, so your bill grows with your business, while a custom build is a fixed cost that doesn't. That creates a crossover. Most people assume the crossover arrives much earlier than it does.

Define:

• S = your all-in monthly platform cost today, including the branded app add-on and any payment processing premium
• B = the one-time cost of a custom build
• M = the monthly cost of keeping a custom build alive

For us, B starts at $12,000 for a bounded MVP and from $25,000 for a full custom build. M starts at $1,000/mo for app maintenance — monitoring, fixes, dependency updates and releases. Those are published prices, on our pricing page, not estimates.

The monthly saving from owning your software is S − M. The payback period is:

payback (months) = B ÷ (S − M)

Now run it. If S is less than M, there is no payback. Ever. A custom build does not save you money until your platform bill exceeds roughly $1,000 a month — and at that exact point it saves you nothing, because you've swapped a subscription for a maintenance retainer.

Work an example. Say your platform bill is $1,500/mo all-in. Net saving is $500/mo. A $12,000 MVP pays back in 24 months. A $25,000 full build pays back in 50 months. During those years you also carry the risk that Apple changes something, that a dependency breaks, that your requirements change, and that the thing you built for the business you had doesn't fit the business you now have.

Say your platform bill is $4,000/mo. Net saving is $3,000/mo. A $12,000 MVP pays back in four months and a $25,000 build in nine. That is a crossover.

The conclusion is uncomfortable and we'll state it plainly: if you're paying under about $2,000 a month for your coaching platform, cost is not a reason to build. Not a weak reason. Not a reason. Anyone who tells you otherwise is quoting you a build cost without a maintenance line, which means they're either inexperienced or hoping you won't notice until year two.

The four reasons that actually justify a build

Cost isn't usually one of them. These are.

1. Your method depends on something the platform cannot express

This is the strongest case, and the test is specific: can you name the feature, and can you name the revenue it's blocking?

Real examples of the shape this takes:

• Readiness-driven auto-regulation. Your programming adjusts today's session based on last night's HRV and sleep from Whoop, Oura or Garmin. Mainstream platforms display wearable data; very few program off it. If your coaching philosophy is "we train to recovery, not to a calendar," you have a genuine software requirement. That's a wearable integration at $3,500 per platform plus the logic on top.
• Form feedback from video. Clients film a lift, and the system evaluates bar path or depth rather than you watching 40 videos a week. That's computer vision, from $12,000, and no coaching SaaS does it well today.
• A clinical or rehabilitative protocol with pain scoring, contraindication rules, red-flag escalation and a practitioner review step. Consumer coaching platforms are not built for this and shouldn't be forced into it.
• A hybrid model where in-gym attendance, remote programming and a nutrition protocol all have to reconcile against one membership.

2. You're selling the software, not the coaching

If the plan is to license your system to other coaches, franchise it, or bundle it with a certification, you're building a product. The economics are completely different — the build is a cost of goods, not an overhead — and so is the scope, because you now need multi-tenancy, per-tenant branding, billing for your customers, and a support function. Budget accordingly and start with strategy, not code.

3. Distribution is your asset

If you have an audience and the app store listing is a channel — your name in the App Store, your reviews, your install base, your push notifications — then owning the listing has value independent of features. Note the qualifier: this only counts if you have the audience now. "We'll build the app and then find the audience" is the most expensive sequence in this business.

4. The manual work has a headcount attached

When you're paying a person full-time to do things the platform can't automate — assembling check-in reports, reconciling payments, manually moving clients between programs — that salary is comparable with a build. But read the next section before acting on it, because the cheap fix is usually available first.

The four reasons that look like reasons and aren't

"The branding is generic." Both platforms sell branded app add-ons. Buy the add-on. If the add-on isn't enough, the honest question is whether your clients have ever mentioned it, or whether it bothers you and only you.

"I want to own my data." You can export it. Check the export format before you sign anything — that's a legitimate diligence step — but "ownership" in the emotional sense is not an engineering requirement. If a specific export limitation is blocking a specific analysis, that's a different and real problem.

"Per-client fees feel like a tax on growth." They are, structurally. And per the math above, they're a cheaper tax than a maintenance retainer until you're well past a thousand a month. Feelings about pricing models are not the same as arithmetic about pricing models.

"One feature is missing." Ask for it. Then check whether a competitor has it — moving from Trainerize to Everfit or vice versa costs a fraction of a build. A missing feature is a reason to switch platforms long before it's a reason to build one.

Stay on the SaaS until all of these are true

This is the section the rest of the article exists for. Stay on Trainerize or Everfit until every one of these has flipped:

• You have more than roughly 200 active paying clients. Below that, per-client pricing is cheap relative to any alternative and your time is better spent on delivery.
• Your platform bill is comfortably above $2,000/mo all-in. Below that, a build never pays back on cost.
• You have named a specific platform limitation that has cost you specific revenue, at least twice, in the last two quarters. Written down, with the amount. Not "it's frustrating." A number.
• You've already asked the vendor to build it and they've said no or "someday." Vendors do ship things. Ask.
• You've tried the middle path below and it wasn't enough.
• You can fund 18 months of maintenance on top of the build, from cash you have, not from revenue you're projecting. A build you can't maintain is worse than no build.
• Your business would survive a three-month migration during which everything is slightly worse. It will be.

If any one of those is still false, stay. That's not us being modest — it's the outcome we've watched play out enough times to have a strong opinion about it.

The middle path, which is what most people should do

There's a large gap between "live inside a SaaS" and "build a platform," and almost nobody sells into it because the projects are small. They're also the projects with the best return.

Automate the ops layer around the platform. Most of what a coaching business's full-time ops person does is moving data between systems: platform to spreadsheet, spreadsheet to email, email to CRM. Each of those is a workflow automation from $99 per process. Ten processes is a thousand dollars and a meaningful fraction of a salary.

Put an AI layer on onboarding and check-ins. Our AI coach assistant starts at $1,999 and ships in 21 days — client onboarding, check-ins, FAQs and plan delivery, trained on your own programs and your own voice. If your bottleneck is that every new client needs 40 minutes of you before they're set up, this is the fix, and it's an order of magnitude cheaper than a platform.

Own the front end even if you rent the back end. Your sales funnel, your landing page, your booking flow and your email sequences should be yours regardless — a funnel build from $999, a landing page from $499. The platform is where clients are served. It doesn't have to be where they're sold.

Build the dashboard the platform won't give you. From $799, on Metabase or Looker Studio, showing the retention and adherence numbers you can't currently see. This is frequently the thing that reveals whether the platform is actually your problem.

If you truly need one custom feature, build only that. A companion app or web tool that does the one thing — the readiness calculation, the video review queue, the protocol engine — and integrates with your existing platform. You keep the billing, messaging and library you're already paying for, and you build the 5% that's actually yours.

Our coach bundles exist for exactly this band, and what we do for fitness coaches is the longer version.

The migration cost nobody counts

Whether you're switching platforms or building, understand what the move costs beyond the invoice.

Rebuilding every program. Your library of workouts, templates and progressions doesn't transfer. Exports exist but they rarely map cleanly across platforms, and the work of re-entering and re-testing is measured in weeks of somebody's time.

Re-onboarding every client. Every client has to download something new, create an account, and find their stuff. Every one of those touchpoints is an opportunity for them to cancel instead. A client who has been coasting for two months and gets an email saying "we're moving to a new app, here's what to do" is a client you may have just reminded to quit. Expect a churn bump and plan the messaging like a launch, not an admin notice.

Payment continuity. If your platform holds your clients' payment methods, moving them is not an export — it's a gateway-to-gateway token migration between payment processors under PCI rules, and it requires cooperation from the provider you're leaving. Ask about token portability before you sign with anyone, including your current vendor. The fallback is asking every client to re-enter card details, which is another cancellation prompt.

History. Progress photos, measurements, session logs and conversations are what make a long-term client feel known. Losing three years of a client's history is a real loss to them. Find out exactly what you can export in what format, and get it before you cancel, not after.

If you do build: what you get and what it costs

A custom coaching platform, scoped as a bounded version one, realistically contains: client accounts and onboarding, program building and delivery, workout logging, messaging, progress tracking, payments, and a coach admin. That's an MVP build from $12,000.

Add the things that made you build in the first place — wearable integrations at $3,500 per platform, computer vision from $12,000, a nutrition layer with a licensed food database — and you're in full custom build territory, from $25,000.

Before either, do the MVP Planning Sprint: $1,500, 5 days — scope, user journeys, prioritized backlog, architecture options, risks and a real build estimate, credited in full toward the build if you proceed. If nothing else, it produces a document you can take to any developer, including one who isn't us. Half the value of that sprint is that it sometimes ends with "don't build this yet," which is a $1,500 answer to a $25,000 question.

Then the ongoing: app maintenance from $1,000/mo, plus the Apple Developer Program at $99/year and a one-time $25 for Google Play. And the thing nobody warns coaches about — the app stores take a commission on digital subscriptions sold in-app, at a standard rate with a reduced tier for smaller developers, and the rules about when you may send users to pay elsewhere have been actively litigated and have changed recently. That commission can be the largest single line in a coaching app's economics, and it needs to be in your model from the first spreadsheet.

The decision, in one table

Frequently asked questions

Is Everfit better than Trainerize?

Neither is better in general. Trainerize is broader, more established and more familiar to clients and coaches, which has real operational value. Everfit is built around automation and team workflows, which suits a business delivering a repeatable protocol to many clients. Trial both with a real client for a week — the answer becomes obvious quickly and no article can substitute for it.

When should a personal trainer build their own app?

When a specific platform limitation is blocking specific revenue you can name, when your method depends on logic no platform offers (wearable-driven programming, video form analysis, a clinical protocol), when you're licensing the software to other coaches, or when your platform bill is well above a couple of thousand a month with a stable business behind it. Under roughly 200 clients, the answer is almost always no.

How much does a custom personal training app cost?

A bounded MVP starts at $12,000 and a full custom build from $25,000, plus maintenance from $1,000/mo. Add $3,500 per wearable platform and from $12,000 for computer-vision features. A $1,500 planning sprint produces a real number for your scope and is credited toward the build. We break the drivers down in what it costs to build your own personal training app.

Will building my own app save money versus Trainerize?

Only if your current platform bill meaningfully exceeds the maintenance cost of owning software, which starts at $1,000/mo. Below about $2,000/mo all-in, a build costs you more, not less — and that stays true no matter how the per-client pricing feels. Cost is a real reason to build eventually; it is rarely the reason people build.

What about a white-label app instead of custom?

It's a genuine middle option and sometimes the right one, particularly if you need to launch in weeks rather than months. It also has trade-offs around app store listing ownership, template-app review policies and data portability that are worth understanding before you commit. We covered it in white-label fitness app vs custom build.

Can I move my clients off Trainerize without losing them?

You can, but treat it as a launch rather than an admin change. Every migration touchpoint is a chance for a coasting client to cancel instead of re-download. Sequence it: export everything first, verify the export, migrate your most engaged cohort first, run both systems in parallel for at least one billing cycle, and confirm payment method portability with both providers before you announce anything.

Should I switch from Trainerize to Everfit, or just build?

Switch first, almost always. A platform migration costs a fraction of a build and answers the question empirically — if Everfit fixes it, you saved $12,000; if it doesn't, you now know precisely what's missing, which makes any subsequent build far better scoped. Tell us what's blocking you and we'll give you a straight read on which of the three it is.
