How it works

From first call to first booking

This is a walkthrough of a gym membership app we build: memberships, class booking and check-ins in one place. Here's how yours comes to life.

  1. Scoping call

    We map what your members actually need: classes, memberships, payments, community. Fixed scope, fixed price.

  2. Design

    Screens like these, designed around your brand and your gym, not a template with your logo on it.

  3. Build

    Native Swift, written by the founder. You get TestFlight builds on your own phone as we go.

  4. Launch & grow

    App Store submission handled end to end, then monthly updates so the app keeps earning its place.

Who you'll work with

One founder. No handovers.

I'm Max, the founder of Appro Digital. When you work with us, you work with me. No account managers, no offshore team, no explaining your business twice.

I design and build native iOS apps for gyms and fitness brands because that's where great apps come from: one person who understands your business, writing every line of code that runs it.

You'll have my direct number from day one. That's not a perk, it's how this is supposed to work.

FAQs

Frequently Asked Questions

Everything you need to feel confident about working together.

1. Why not just use a white-label gym app?

White-label apps look identical to every other gym's, lock you into per-member monthly fees and you never own the code. We build yours from scratch in native Swift and you own everything.

2. How long does a gym app take to build?

Most member apps ship in 4 to 8 weeks depending on scope. You see working builds on your own phone throughout, not just at the end.

3. Do you handle App Store submission?

Yes, end to end. Listing copy, screenshots, review process and release. Your app goes live under your own developer account, so you stay in control.

4. Can it integrate with my existing membership software?

In most cases, yes. We scope integrations with your current booking or membership systems during the discovery call and tell you plainly what is and is not possible.

5. Who owns the app?

You do. Full source code handover is included in every tier. If we ever part ways, you keep the app, the code and the App Store listing.

6. Do you build Android apps too?

We build native iOS first, because that's where premium fitness and health audiences overwhelmingly are, and doing one platform properly beats doing two averagely. If Android matters for your business, we'll tell you honestly and scope the right path during the call.

7. What does the monthly plan actually cover?

Hosting and maintenance, iOS updates and compatibility, bug fixes, and ongoing improvements to the app each month. It's what keeps your app alive and improving after launch, rather than quietly rotting.

8. Do you build health and wellness apps?

Yes. Alongside gym and coaching apps we build health apps, tracking, protocols, reminders and progress. We design with sensitive data in mind and will tell you plainly during scoping what your app does and doesn't need to handle.
