The reason it's hard to find a straight answer to this question is that most development shops don't publish prices, and the ones that do are usually quoting a template. So here is ours, up front: a bounded version one of a personal training app starts at $12,000. A full custom build starts at $25,000. Maintenance starts at $1,000/mo and is not optional. Every one of those numbers is on our pricing page and has been before you got here.
What follows is what moves those numbers, what the low end actually contains, and the costs that appear after the invoice is paid.
Why the range is so wide everywhere else
Two structural reasons, and neither is a conspiracy.
Scope is genuinely elastic. "A personal training app" describes anything from a program-delivery app for one coach's 40 clients to a multi-tenant platform with wearable integrations, video analysis and a nutrition engine. Those differ by an order of magnitude in real work.
Hourly billing punishes clarity. If a shop bills by the hour, a vague scope is not their problem — it's their upside. We price fixed, which forces the scoping conversation to happen before anyone commits, and means the elasticity gets resolved on paper rather than on an invoice.
Enterprise consultancies quoting six figures for a coaching app aren't necessarily overcharging; they're pricing a delivery structure with account managers, multiple environments, formal QA gates and compliance documentation, aimed at a client who requires all of that. If you're a coach with 300 clients, you don't require all of that. You're being sold a process, not a product.
What $12,000 actually contains
An MVP build at $12,000 is a bounded version one — a working product in the stores, not a prototype. For a personal training app, a realistic version one is:
- Client accounts and onboarding — signup, intake questionnaire, goal capture, coach assignment
- Program building and delivery — the coach creates a program, the client receives it on a schedule
- Workout logging — sets, reps, load, notes, with a history the client can see
- Progress tracking — measurements, photos, a chart that means something
- Coach–client messaging
- Payments — subscription billing through a real processor
- A coach admin surface — because you have to run this thing
- Store submission on iOS and Android, from one codebase
That's a real business in an app. It is also a short list on purpose. The thing that keeps an MVP at $12,000 is not cheaper engineering; it's a smaller decision set.
What $12,000 does not buy
Being explicit, because vagueness here is how projects go wrong:
- Every feature on your list. That's what the scoping sprint is for.
- Wearable sync. Each platform is its own project.
- Video form analysis, rep counting or food recognition.
- A licensed food database with barcode scanning.
- Live video coaching or streamed classes.
- Multi-tenancy — the ability to sell your app to other coaches under their brand.
- A year of changes after launch.
- Native iOS and native Android as two separate codebases.
None of those are unreasonable to want. They're just not in the same box.
The features that multiply the number
| Feature | What it adds | Why |
|---|---|---|
| Wearable integration | [$3,500 per platform](/services/custom-software/wearable-integrations) | HealthKit, Health Connect, Garmin, Whoop, Fitbit and Oura are six separate projects with different auth, different data models and different failure modes. Deduplication, background delivery and timezone handling are most of the work |
| Computer vision | [From $12,000](/services/custom-software/computer-vision-fitness) | Pose estimation, rep counting, form feedback or food recognition. Priced after discovery because accuracy requirements drive everything |
| Nutrition with a food database | Build cost plus recurring licensing | The API licence is an ongoing bill that scales with logging volume. See [nutrition coaching app development](/blog/nutrition-coaching-app-development) |
| Video content at scale | Build plus recurring | Storage, transcoding and delivery. A library of 400 exercise videos is an infrastructure line item forever |
| Live video sessions | Meaningful | Real-time infrastructure, per-minute costs, and a support surface when someone's connection drops mid-session |
| Offline mode | Meaningful | Sync conflict resolution is genuinely hard. Worth it if clients train in basement gyms with no signal — which many do |
| Multi-tenancy / white-label for other coaches | Substantial | Tenant isolation, per-tenant branding, tenant billing, and a support function. This is a different product |
| Two native codebases instead of one | Roughly doubles the app layer | Only justified when you need deep platform-specific behavior, such as reliable background Bluetooth |
| Multi-language | Moderate and recurring | Not just strings — dates, units, and content that has to be maintained in every language forever |
Which of those rows apply to you is the whole question, and the answer changes the total by a multiple rather than a margin. Estimating it against your own scope takes a couple of minutes and is more informative than any table someone else wrote, because it prices the combination you are actually considering.
The single most common budget mistake we see is treating wearable sync as a checkbox. "It connects to Apple Watch" is one line on a feature list and two to four weeks of engineering, because the API call is the easy part and the merge rules, unit normalization, permission-state recovery and real-device QA are the rest of it.
The costs after launch
This is where most budgets are wrong, and it is not a small correction.
App maintenance from $1,000/mo. A live mobile app is not a finished object. Operating systems ship annually and break things. Google Play requires apps to keep targeting a recent Android API level in order to remain updatable. Apple requires builds against a recent SDK. Third-party SDKs deprecate on their own schedule. Payment APIs version. An app with no maintenance retainer stops working within about eighteen months, and it will stop working on a morning when your clients are trying to open it.
Apple Developer Program: $99/year. Google Play: $25, one time. Small, mandatory, and routinely forgotten in the spreadsheet.
QA from $799/mo, if you're shipping regularly. Our QA and release package is $999 for a one-off readiness cycle if you'd rather do it per release.
App store commission on in-app digital purchases. If clients subscribe inside your app, Apple and Google take a percentage. There's a standard rate and a reduced rate for smaller developers below a revenue threshold, and the rules governing when you may direct users to pay outside the app have changed materially through recent litigation in the US. This can be the largest single cost in a coaching app's P&L. Model it before you build, not after.
Infrastructure. Modest at coaching scale — hosting, database, storage, email and SMS — until video enters the picture, at which point storage and bandwidth become a real line.
Third-party services. Payment processing, transactional email, SMS, push, error monitoring, analytics. Individually small, collectively a few hundred dollars a month.
Add it up. The honest floor for owning a personal training app is the build plus something in the region of $1,200–$1,500 a month to keep it alive and healthy, before you add a single feature. If that number doesn't fit, the right answer is not a cheaper developer — it's not building yet. Our comparison of Trainerize, Everfit and custom works through exactly when that flips.
How to spend less, genuinely
Do the planning sprint first. $1,500 over 5 days: problem definition, user journeys, MVP scope, prioritized backlog, release roadmap, architecture options, risks, acceptance criteria and a real build estimate — credited in full toward the build. The reason this saves money is that it converts arguments into decisions before those arguments are expensive. It also produces a document you can take to any developer, which is the point.
Cut features, not quality. Every project has a version where half the features are gone and the product is still viable. Find it. Quality cuts — skipping QA, skipping edge cases, skipping the permission-denied state — come back as support load and one-star reviews, which cost more than the features you kept.
Ship one platform first if your clients are on one platform. Check your own client list. If 85% are on iPhone, build iOS first and add Android when the revenue justifies it.
Add one wearable, not six. Instrument the connect button. If a small fraction of clients connect the first platform, you've saved $17,500 on the other five.
Keep the SaaS running underneath. You can build only the differentiated piece — the readiness engine, the video review queue, the protocol logic — and keep paying a platform to handle billing, messaging and the exercise library. Much smaller build, much smaller risk.
Buy the small things instead. If the actual bottleneck is onboarding load, an AI coach assistant from $1,999 ships in 21 days and may remove the reason you wanted an app. If it's lead flow, a funnel build from $999 does more for revenue than any feature. Our fitness coach bundles sit in exactly this band.
Timeline
Most of our packages ship in 5 to 21 days. A custom app is the exception, and we'd rather say so than imply otherwise.
- Planning sprint: 5 days.
- MVP build: weeks, driven by scope. The scoping sprint gives you the specific number, and it's the only honest way to produce one.
- Each wearable integration: 2 to 4 weeks per platform, and they can overlap with the main build.
- App store review: days, usually, and occasionally longer if health-adjacent claims in your listing get a second look. Budget a buffer around any launch date you announce publicly.
Anyone quoting you a full coaching platform in two weeks is quoting a demo. Anyone quoting nine months for a version one is quoting a process.
The number to take away
If you're a coach with a working business and a specific reason to build:
- $1,500 to find out what it costs and whether to do it, credited toward the build
- $12,000+ for a version one in both stores
- $3,500 per wearable platform, if you need one
- $1,000+/mo to keep it alive
If those numbers work, tell us what you're building and who it's for and we'll tell you what it actually takes — including if the answer is that you shouldn't build it this year. More detail on personal trainer app development and the wider fitness app practice.
Frequently asked questions
How much does it cost to build a personal training app?
A bounded MVP starts at $12,000 and a full custom build at $25,000, with maintenance from $1,000/mo. Wearable integrations add $3,500 per platform and computer-vision features start at $12,000. A $1,500 planning sprint produces a specific number for your scope and is credited toward the build.
Why do some agencies quote six figures for a fitness app?
Usually because they're pricing an enterprise delivery structure — dedicated account management, multiple environments, formal QA gates, compliance documentation — and often because they bill hourly against an open scope. That structure is appropriate for a regulated healthcare product with a large client organization. It is not what a coaching business with a few hundred clients needs, and paying for it doesn't make the app better.
Can I build a fitness app for $5,000?
Not a production app with accounts, payments, program delivery and store submissions. You can get a clickable prototype or a marketing site with a booking flow for well under that, and for many coaches those solve the actual problem. Our healthcare prototype starts at $3,500 if what you need is something to test or to show investors.
What's the ongoing cost of a fitness app?
Realistically $1,200 to $1,500 a month before new features: maintenance from $1,000/mo, $99/year for the Apple Developer Program, $25 once for Google Play, plus hosting, email, SMS and monitoring. If you sell subscriptions inside the app, the store commission is a separate and often much larger cost.
Should I build native or cross-platform?
Cross-platform — Flutter or React Native — for the overwhelming majority of coaching apps. One codebase, both stores, and the performance ceiling is far above what a coaching app needs. Go native when you need deep platform behavior that cross-platform frameworks handle poorly, with reliable background Bluetooth being the most common trigger.
Do I need HIPAA compliance for a personal training app?
Usually not. Ordinary coaching data — workouts, weight, goals, photos — isn't protected health information unless you're operating as or on behalf of a covered entity, billing insurance, or delivering clinical services. It changes if you're partnering with a healthcare provider or handling medical records. That's a scoping question worth resolving early; see HIPAA-aware development. We build to that boundary and are clear about where our work ends — we don't issue certifications or legal sign-off.
