From personal trainer app development to studio and subscription products, we build fitness apps in Flutter and React Native. Scoped upfront, quoted upfront, delivered as one product with booking, payments, and a paywall that actually converts.
Most requests fall into one of these. If yours sits across two, we scope it as one product rather than bolting features together later.
Studios, gyms, and independent trainers taking session bookings, managing calendars, and handling cancellations without phone calls and spreadsheets.
Structured training plans, progress logging, and a coach dashboard for one-to-one or group programs. This is the heart of personal trainer app development, where the trainer runs their whole practice through the app.
Workout libraries and wellness content behind a paywall, with trials, tiers, and a subscription flow built to turn first sessions into renewals.
Evesport connects trainers with the people who train with them. Clients find a session and book it in a few taps. Trainers manage their availability, their roster, and their prices in one place, without running a calendar on the side.
We took it from kickoff to launch in twenty weeks, on a fixed price, and it landed a 4.9 average trainer rating with bookings up 18 percent in the first sixty days.

A fitness app looks simple in a mockup. The difficulty lives in the details that only show up once real people and real schedules hit it.
Holding a slot and confirming a slot are separate moments, and the gap between them is where double bookings happen. Two clients tapping the same 7 AM session at once, a payment that fails after the slot is reserved, a trainer editing availability while someone is mid-checkout.
We treat the slot lock and the confirmation as two steps with a clear expiry between them, so the calendar never promises the same session twice.
The paywall is not a screen you add at the end. Where it appears, what the trial looks like, and how tiers are framed change whether a first-time user ever becomes a paying one. We build the subscription flow as a first-class part of the app and make it easy to adjust the paywall without a new release.
On a recent fitness build we shipped a dynamic paywall driving the subscription conversion, tuned around what users actually did in onboarding rather than a fixed guess.
Apple HealthKit, Google Fit, and wearable integrations can add real value, but they also add cost, permission flows, and edge cases. We are honest about when they matter for your users and when they are a phase-two feature rather than a launch requirement.
If your product needs step, heart rate, or activity data, we scope it deliberately. If it does not, we leave it out so the first version ships on time.
A live trainer booking app with a real rating and real bookings, not a portfolio of concepts. You are hiring a team that has already solved the hard parts of a fitness app once.
We scope the first version in a discovery step, then quote a fixed price for it. Everything agreed in that scope is our responsibility to make work, not a source of extra invoices.
Booking, payments, content, and the paywall are designed to work together from the start, so nothing has to be retrofitted after launch.
A senior engineering team that works to your timeline, communicates in plain English, and treats your deadline as real.
We map who uses the app, what a session or subscription really involves, and where the edge cases hide.
You get a scoped first version and one fixed price, with what is in and what waits for later stated plainly.
We build in short iterations you can see, with booking, payments, and the paywall wired together as we go.
We ship to the App Store and Google Play, and everything in the agreed scope works, that is the deal.
Either works well. We choose per project based on your product, your team, and any native integrations you need, and we tell you why. Neither is forced on you.
A focused first release is typically eight to twelve weeks. A fuller product like a booking app with trainer tooling and subscriptions runs longer, and our own trainer app went kickoff to launch in twenty weeks.
Yes. We build the subscription flow, trials, tiers, and the store rules for Apple and Google, and set up the paywall so you can adjust it without shipping a new version.
When it earns its place. We support Apple HealthKit, Google Fit, and wearable data, and we are honest about whether your users need it at launch or later.
Every fitness app is scoped before it is priced, so you get a fixed quote for your product rather than a range. Our guides below walk through what drives the number.
One person who can make decisions, a clear picture of your first version, and access to accounts and any existing assets. We handle the rest.
Tell us what you want to build. We will scope a first version and come back with a fixed price and a realistic timeline.
