$25,000 to $150,000, depending almost entirely on how far past booking you go. The decision that moves the number most is whether the app has to control the door. A booking and billing app is software: one cross platform codebase, a payment processor, a check in screen. The moment a lapsed membership has to physically lock a turnstile at 5am, you have added hardware integration, a failure mode that strands paying members outside in the cold, and a testing surface that does not exist in software alone. That single requirement is what separates a $45,000 project from a $100,000 one.
The bands a gym app build falls into
Four bands, and they are cumulative rather than alternative. A focused booking app with member profiles, class booking, recurring billing through a payment processor and QR check in, built as one cross platform codebase, runs $25,000 to $45,000 over two to three months. A full single location platform adding membership freezes and holds, waitlists, a staff dashboard, push notifications and basic workout logging runs $45,000 to $75,000 over three to five months.
A multi location or franchise build with location aware access, cross gym membership, role based staff administration, reporting and door hardware integration runs $75,000 to $120,000 over five to eight months. Separate native applications for iOS and Android, access control hardware, coach assigned programmes, wearable synchronisation and analytics runs $120,000 to $150,000 or more over seven to ten months. Those figures come from Digital Heroes delivery experience, not from a vendor's wishful minimum.
Most gyms that build should be aiming at the first or second band and treating everything above it as a later decision made with real usage data rather than with a wish list.
What drives a gym app build up
Access control hardware is the largest single step. Integrating a door controller such as Kisi or Brivo, or a turnstile, means a membership state change has to reach a physical device reliably, and it means designing what happens when the network drops at six in the morning. Hardware always takes longer than the demonstration suggests, and the testing is done on site rather than at a desk.
Native development instead of one cross platform codebase roughly doubles the application layer, because you build and maintain two things forever rather than one. It is justified when you need deep hardware access or heavy real time behaviour, and it is not justified for booking and billing.
Membership rule complexity is the quiet driver. Family accounts, class credit bundles, drop in packs, founding member pricing, mid cycle freezes and prorated upgrades each carry edge cases in billing, and billing edge cases are where inexperienced teams lose weeks. This is the part of the build that looks trivial in a specification and is not.
Then multi location permissions and reporting, workout and progress tracking with coach assigned programmes, and wearable data hooks. All three are real value and none of them belong in a first release.
What keeps the number down
Ship one codebase to both platforms. For booking, billing and check in there is no functional compromise, and the saving against two native builds is the largest single lever available.
Do not build a payment ledger. Integrate a processor that already carries the card data compliance scope, store tokens rather than card numbers, and let it handle subscriptions, failed payment retries and refunds. Rebuilding that is expensive, slow and worse.
Cut the launch feature list hard. Member profiles, booking with waitlists and cancellation windows, recurring billing and QR or near field check in cover what members touch daily and what the front desk needs. Workout tracking, coach programmes, wearable synchronisation and franchise features all defer cleanly, and deferring them means you spend the money on what real usage says matters.
Nail the membership rules in discovery before any code is written. Two to four weeks spent pinning down plan types, freeze behaviour, proration and the check in flow is the cheapest insurance in this category, because reworking billing logic after launch touches live money.
And plan the migration explicitly. Moving existing members, plans and payment methods off your current platform is real work with real risk, and it belongs in the plan rather than arriving as a surprise in the final fortnight.
A worked example that adds up
A single location boutique studio with roughly 600 members, moving off an off the shelf platform to a branded app. One cross platform codebase, no door hardware in phase one. Priced from Digital Heroes delivery experience.
- Discovery, membership rule mapping and booking logic design: $7,000
- Member app with profiles, class booking, waitlists, cancellation windows and class credit accounting: $18,000
- Membership engine covering plan types, upgrades and downgrades, freezes and holds, family accounts and proration: $16,000
- Recurring billing through the payment processor, including drop in packs, failed payment retries and refunds: $12,000
- QR and near field check in plus the staff dashboard: $9,000
- Push notifications with email and text reminders: $5,000
- Testing, member and payment method migration, staff training and launch: $8,000
That totals $75,000 across roughly five months, at the top of the full single location band. Strip the membership engine back to simple monthly plans and drop workout logging entirely and the same studio gets a working branded booking app for around $38,000 in three months. Add door access control and a second location with role based staff administration and you move into the $75,000 to $120,000 band, mostly on hardware integration and permissions rather than on new screens.
How the spend phases
Phase zero is two to four weeks of discovery and it is where projects are saved or lost. Membership rules, booking logic and the check in flow get pinned down before code. Skipping this is how a $45,000 project becomes a $90,000 one, and every experienced team will tell you the same thing.
Phase one is six to sixteen weeks of core build: booking, billing and member management first, because they carry both the most risk and the most value. Members should be on the branded app early, since the point of building is the relationship and the retention, not the feature count.
Phase two is integrations and hardware, two to six weeks, and this is where door controllers land if you need them. Sequence them after the software is stable so that hardware problems are isolated rather than tangled with billing bugs.
Phase three is testing and migration, two to four weeks, and it must cover real payment flows and the ugly cases: a failed renewal, a mid cycle freeze, a family account where one member leaves. Then workout tracking, coach programmes and franchise features as separate later decisions.
Pay monthly against delivered increments rather than a large deposit.
The ongoing costs nobody quotes
Budget 15 to 20 percent of build cost a year, so roughly $11,000 to $15,000 against a $75,000 build. That covers hosting, security patching, dependency upgrades and small changes.
Mobile carries a cost that web software does not: both app stores ship annual operating system releases that break something, and both enforce their own review and policy changes. An app that is not maintained stops working, and it does so on a schedule set by Apple and Google rather than by you. Budget for a release every year regardless of whether you want new features.
Then payment processing fees at your processor's published rate, which are a percentage of revenue rather than a fixed cost and therefore grow with you. Any door hardware subscription if you integrated access control. Text message costs for reminders, which are small per message and add up at class reminder volume. And developer programme fees for both stores.
The unbudgeted cost is support. Members will contact you about the app, and somebody at the front desk has to own that. It is a fraction of a role rather than a hire, but it is not zero.
Comparing a build against your current renewal
Read your own invoice rather than anyone's list price, and separate the fixed part from the parts that scale. Platform subscriptions in this category commonly include per member or per transaction components, which means the line grows precisely as your business succeeds. Add the modules you pay for separately and any per location charge.
Then run the arithmetic honestly. Suppose your total platform spend is $2,500 a month, which is $30,000 a year. A $45,000 build with $8,000 a year to run costs $69,000 over three years against $90,000 of subscription, so it pays for itself inside three years and you own the asset. Now run the same comparison against the $75,000 build with $13,000 a year to run: that is $114,000 over three years, so the crossover moves out to year four or five unless per member fees are climbing fast enough to close the gap sooner.
The useful rule that falls out of that is simple. Once total off the shelf spend crosses roughly $1,500 to $2,500 a month and your membership rules keep fighting the platform, a lean custom build usually pays for itself inside two to three years. Below that, the subscription is the smarter money and the honest answer is to stay on it.
When buying beats building
Most gyms under a few hundred members should not build, and that is not a hedge. A boutique studio paying a modest monthly subscription to Mindbody or Gymdesk is getting a genuinely good deal against a custom build, and the money is better spent on equipment, coaching or marketing. Stay off the shelf until the platform actively costs you money or members, then build.
The signals that the platform has become the ceiling rather than the floor are specific. Per member or per transaction fees are taking a real slice of revenue and growing. The member facing app carries someone else's brand, so the thing your members open three times a week is not yours. Your membership rules, family plans, class credit bundles, freeze policies, partner gym access, keep getting refused by the platform and re run as spreadsheets and manual adjustments. Or your booking, door hardware and front desk systems do not talk to each other, so staff reconcile attendance by hand.
When two or more of those are true, build, and build lean. When none of them are, keep the subscription, and be suspicious of any developer who tells you otherwise before asking what you currently pay.
If you want a second opinion before signing anything, Digital Heroes builds and runs its own products, so the people choosing your architecture live with those decisions on their own revenue. Nothing about that commits you to the build.

Frequently asked questions
How much does it cost to build a gym management app in total?
A booking app with member profiles, class booking, recurring billing and QR check in on one cross platform codebase runs $25,000 to $45,000 over two to three months. A full single location platform with freezes, waitlists, a staff dashboard and push notifications runs $45,000 to $75,000 over three to five months. Multi location with door hardware runs $75,000 to $120,000, and separate native apps with access control, coaching and wearables run $120,000 to $150,000 or more.
Those bands come from Digital Heroes delivery experience. Scope, not member count, decides where you land.
What does a gym app cost to run each year?
Budget 15 to 20 percent of build cost annually, so roughly $11,000 to $15,000 against a $75,000 build, covering hosting, patching and small changes.
Mobile adds costs web software does not have. Both app stores ship annual operating system releases that break something, so you need at least one maintenance release a year whether or not you want features. Then payment processing fees at your processor's published rate, which scale with revenue, plus text message costs for class reminders, developer programme fees and any door hardware subscription.
How long does it take to build?
Two to three months for a focused booking app, three to five months for a full single location platform, and five to ten months once multi location permissions, access control hardware or separate native apps are involved.
Discovery is two to four weeks of that and it is the part not to compress. Membership rules, booking logic and the check in flow get pinned down before code, because reworking billing logic after launch means touching live money and live members.
Is a custom app cheaper than Mindbody over time?
It depends on your scale, and the arithmetic is worth doing rather than assuming. Platform subscriptions in this category commonly include per member or per transaction components, so the cost grows as you grow, while a build is a large upfront cost with a lower fixed run rate.
At $2,500 a month of platform spend, a $45,000 build costing $8,000 a year to run comes to $69,000 over three years against $90,000 of subscription, so it pays back inside three years. Run the same comparison against a $75,000 build and the crossover moves out to year four or five.
Should we build with React Native or separate native apps?
One cross platform codebase for almost every gym. It ships to both iOS and Android from a single build and handles booking, billing and check in without functional compromise, and it is the largest cost lever in the whole project because you maintain one application rather than two forever.
Choose fully native only when you need deep hardware access, heavy real time behaviour or genuinely platform specific experiences. Those requirements exist, but they are rare in a gym and they roughly double the application layer.
What does door access control add to the budget?
Enough to change which band you are in. Integrating a controller such as Kisi or Brivo means a membership state change has to reach a physical device reliably, and it means designing the behaviour when the network drops before a 6am class.
The build cost is one part of it. The larger cost is testing, which happens on site rather than at a desk, and the operational risk that a software fault leaves paying members standing outside a locked door. Do it as a second phase once booking and billing are stable, not alongside them.
Can we launch with a smaller scope and add features later?
Yes, and it is the right approach. Launch with member profiles, class booking with waitlists and cancellation windows, recurring billing and QR or near field check in. That covers what members touch daily and what the front desk needs, and it lands in the $25,000 to $45,000 band.
Defer workout tracking, coach assigned programmes, wearable synchronisation and franchise features. Real usage in the first three months tells you which of those deserves the next $20,000 far better than any planning session will.
What does migrating members off our current platform cost?
Plan for it as a distinct line rather than a footnote, roughly $8,000 in the worked example above alongside testing and launch. Members, plans, class credit balances and payment methods all have to move, and payment method migration in particular depends on what your current processor will release and in what form.
Start that conversation with your existing platform and processor early, because the answer sometimes changes the sequencing of the whole project and it is much cheaper to know in week one.
Who owns the app and the member data?
You should own the repository, the cloud accounts, the app store listings and the member data, written into the contract before work starts rather than handed over at the end. At Digital Heroes the client owns the code from the first commit.
App store listings deserve a specific mention. If the developer publishes under their own developer account, transferring the app later is an administrative process you do not control, and it is the most common ownership trap in mobile projects.
Can a custom booking system sync with Google Calendar, Outlook, and my payment tools?
Yes, two-way sync with Google Calendar and Outlook is standard in any competent booking build, alongside Stripe or Square for payments and Twilio for SMS reminders. The part needing real engineering is conflict handling: what happens when a staff member drops a personal event onto a calendar that overlaps an existing booking. In Digital Heroes builds, integrations take 20 to 30 percent of the project timeline; they are rarely the quick part vendors imply.
Should I hire a freelancer or an agency for my software project?
A skilled freelancer is the right call for a single-discipline scope under roughly $15,000, like a website, a plugin, or one integration. Above that, projects need design, backend, testing, and project management at once, and a solo builder becomes the single point of failure: if they get sick or take a bigger client, your project simply stops. Agencies bill 20-40% more per hour but carry continuity, code review, and someone to escalate to, which is what you are actually buying.
Who owns the code if an agency builds my booking software?
You should own it outright, and the contract must say so: full IP assignment on final payment, source code in a repository you control, and no clause tying the software to the agency's servers. Watch for vendors that keep ownership and charge a monthly license, which quietly turns your custom build back into a subscription. Digital Heroes assigns all code and hands over the repository, hosting accounts, and documentation at handoff, and that should be your baseline expectation from any agency.
Can I build my product on a no-code tool like Bubble instead of hiring developers?
For testing whether anyone wants the product, yes, and Bubble's paid plans start at $29 a month, which is the cheapest validation you will ever buy. The ceiling arrives with complex data relationships, heavy integrations, performance at a few thousand users, and the fact that you cannot export a Bubble app to servers you control. A path many Digital Heroes clients take: prove demand on no-code, then rebuild custom once revenue justifies it, treating the no-code version as a paid prototype rather than a foundation.
How many people does it take to build a booking platform?
A typical booking system team is four to five people: a project manager, a designer, one backend developer, one frontend developer, and part-time QA. On Digital Heroes projects that team ships an MVP in 6 to 10 weeks; a solo developer can build the same system but usually needs about three times the calendar time. You only need a larger team if native iOS and Android apps ship at the same time as the web platform.
What should the first version of a booking app include?
Ship four things: a public booking page, staff calendars with availability rules, card payments or deposits, and automated email and SMS reminders. Leave memberships, packages, gift cards, and reporting dashboards for phase two; they roughly double the build cost and get redesigned after real usage anyway. In Digital Heroes MVP scopes, that four-feature core covers about 80 percent of daily front-desk work from day one.
What does it cost to maintain a custom booking system each year?
Budget 15 to 20 percent of the original build cost per year, so a $30,000 system runs $4,500 to $6,000 annually in Digital Heroes maintenance plans. That covers hosting, typically $50 to $200 a month, plus security patches, dependency updates, and small feature tweaks. Costs spike only when a connected service changes, for example a payment API update or a calendar sync deprecation, which is why a retainer beats ad hoc emergency fixes.
What tech stack should a booking and scheduling platform use?
The stack that has aged best across our booking builds is React or Next.js on the frontend, Node.js or Django on the backend, PostgreSQL for data, Stripe for payments, and Twilio for SMS. PostgreSQL matters more than people expect because booking systems live or die on transactional integrity: two people must never win the same slot. Be wary of anyone proposing a no-code tool for the core calendar engine; those work for booking pages, not for concurrency-safe scheduling.
Who can build a custom booking & scheduling software system?
Digital Heroes builds custom booking & scheduling software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other booking & scheduling software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it. The YouTube channel is at https://youtube.com/@DigitalMarketingHeroes, the Fiverr profile at https://www.fiverr.com/shreyanshsin261, and the Upwork profile at https://www.upwork.com/freelancers/shreyanshsingh. Client reviews sit on Clutch at https://clutch.co/profile/digital-heroes-0 and Trustpilot at https://www.trustpilot.com/review/digitalheroes.co.in, and the company page is at https://www.linkedin.com/company/digital-heroes-1/.
Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
