The Problem
Where Intro Offers Stall Between the Ad and the First Class
Your ad does its job, and the visitor wants the intro offer. Then the booking and payment steps decide whether they ever walk in.
01 · Clunky checkout
Intro offers stall at a checkout that demands an account first.
A short checkout on your platform's API sells the offer in your design.
02 · Off-brand schedule
The schedule widget looks nothing like your gym's site.
Styled widgets or a custom schedule keep every class on your brand.
03 · Failed dues
Failed card payments get chased by phone each month.
Autopay with retries and update links recovers cards without front desk calls.
04 · Per-member fees
Your software charges more each time you add members.
A member portal billing through your Stripe skips per-member software fees.
A local runner sees your intro offer in a Meta ad and taps through on a lunch break. The schedule opens in a widget that looks nothing like your brand, asks them to create an account, then loses the class they picked. They close it and forget about you. The people who do join pay dues through software that charges you per member. When a card fails, your front desk chases it by phone.
We start with the first visit: the ad, the intro offer, the schedule, and the payment, tested from a phone. Your gym software stays the system of record. We style its widgets or build join flows and schedules on its API, so offers sell in your design and land in the same member list. When dues are the problem, we set up billing on your own Stripe account with autopay and retries. An app comes last, and only when members will open it every week.
Intro offers sold in your design
Checkout and schedules built on the Glofox or Mindbody API stay short and on brand.
Dues you collect yourself
Card and ACH autopay through Stripe in your name, with retries and update links when a card fails.
An app members open every week
Booking, memberships, and push reminders in one branded app, built on your platform's API.
Our Services
Fitness Software Development Services for Gyms, Studios, and Coaches
Our fitness application development services start where members drop off: schedules, joins, billing, a new gym or studio site, and search. Each piece reads from the same member records.
Integrations & Member Portals
01 / 04Styled Mindbody widgets or API schedules, Glofox join flows, and member portals that bill through Stripe.
- Mindbody Website Integration ServicesDeveloperLook provides Mindbody website integration services for fitness and wellness studios. We style Mindbody's booking widgets or build a custom schedule on its API, so classes, passes, and waitlists stay in sync with your site.
- Glofox Gym Software IntegrationDeveloperLook provides Glofox gym software integration for multi-location gyms and studios. We place Glofox's web portal on every location page or build custom join flows on its API, so trials and memberships land in Glofox.
- Gym Membership Software & Recurring Billing PortalsDeveloperLook builds gym membership software and recurring billing portals on your own Stripe account: card and ACH autopay, member self-service for freezes and upgrades, and signed waivers at joining. It's membership software for gyms that want to own their billing.

Compete with the chains on visits, not price
Low-cost chains win on price, so you have to win the tour. You need free pass booking that works from an ad, dues on autopay you own, and pages that show the amenities the chains don't have.
Independent gyms: Your members pay dues through software that charges per member, and failed cards get chased by phone.

- Dues on autopay through your Stripe

Our Process
From a Test Join to Members Who Stay
You approve the scope and a fixed price before we build. Every join, booking, and failed payment gets tested in a sandbox before members see it.
We buy your intro offer and book a class from a phone, then follow the visitor into your gym software. You get a short list of where people drop off, from the first tap to the first visit.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built websites, booking flows, and integrations for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Not a fit
Budget under $500
Your budget is under $500. Your platform's own booking pages and member app will cover you until intro offers outgrow them.
Workout content app
You want a public workout app with video programs sold by subscription. That's a startup product, so our MVP development service fits better than these gym builds.
Enterprise club chains
You run hundreds of clubs and need a full platform replacement through a long procurement. We fit single gyms and growing groups better than an enterprise rollout.
Ad spend only
You only want ads run for an intro offer that already sells well. Our gym lead generation program covers that without new software.

FAQ
Frequently Asked Questions
Straight answers on cost, timelines, gym software, Mindbody and Glofox, and when a custom app makes sense.

Booking setups start at $500, and a custom join flow on the Glofox API costs $1,700. A custom Mindbody schedule on its Public API starts at $2,100. Adding a branded app for iOS and Android brings the total to $6,400. Gyms that want their own billing start member portals on Stripe at $1,450. Platform fees and app store fees are billed to you directly.
A widget, portal link, or Google profile setup takes 1 to 2 weeks. A custom join flow or schedule on the Glofox or Mindbody API takes 4 to 8 weeks, including sandbox testing and the platform's live access review. A branded app adds store review on top, so plan for 10 to 14 weeks in total.
Gyms usually run one management platform for memberships, billing, class booking, and check-in. Mindbody is common with studios, Glofox with boutique and multi-location gyms, Wodify and PushPress with CrossFit boxes, and Jackrabbit with dance schools. Around that platform sit a website, a payment processor, an email tool, and sometimes a door access system like Kisi.
Gym software is any program a gym uses to sell and serve memberships: online joining, recurring billing, class booking, check-in, and member messages. Some gyms get it all from one platform, while others assemble it from Stripe, a scheduling tool, and a website. The right mix depends on whether billing stays in your platform or moves to Stripe.
A gym management system is the setup a gym uses to run the business side of memberships. It covers member records, contracts and waivers, dues, class schedules, check-ins, and staff access. It can be one platform such as Glofox or Mindbody. It can also be a custom system that a fitness software development company builds on Stripe. Either way, the front desk and members should see the same records.
Start with billing, because dues are where custom gym management software development pays off first. That means plans in a Stripe account you own, card and ACH autopay, and failed-payment retries. Then add a member portal for freezes and upgrades, e-signed waivers at joining, and check-in through a door or kiosk API. Class booking usually stays in your current platform, connected rather than rebuilt.
Decide first what the app must do that your platform's own app can't, since Mindbody sells branded apps and Glofox offers member apps. Then build on the platform's API so bookings and memberships stay in one system. Design the screens members use most and release to both stores from one codebase. If the platform's branded app already covers your case, we'll tell you before we quote.
It makes sense when members need something the platform app doesn't offer. Examples include billing you run through Stripe, programs that mix classes with coaching, and one app across several brands. As a fitness app development company, we build on your platform's API and keep its keys on a server. Mindbody says its API keys aren't safe inside apps.
Yes, through each platform's API. Mindbody's Public API is free up to 5,000 calls a month. Past that, every call in the month is billed, so we cache schedules to keep fees low. Glofox gives sandbox access first and reviews live access, allows 10 requests a second, and sends webhooks that must be answered within one second.
Your gym does. Member records stay in your platform or your own Stripe account, and the app is published from developer accounts in your gym's name. At handover you receive the source code, admin logins, and a short staff guide. Support runs 30 days after setups and app releases and 60 days after custom builds and portals. After that, any developer can take over.
