AKTIV was built for when “off-the-shelf” no longer makes the cut
Legacy off-the-shelf fitness software and apps work for a while, but fitness brands quickly run up against limitations requiring workarounds and heavy ongoing licensing costs. We solve this challenge.
Aging club management software accumulates licensing fees, workarounds, and integration costs (OpEx). We modernize and replace legacy fitness platforms with systems you own and control (CapEx).
Member data sits within vendor platforms that limit what you can export or integrate. We build unified data layers that bring membership, usage, wearable, and commerce data together so you can measure and personalize.
Packaged fitness software dictates how check-in, onboarding, billing, and staff processes work. We develop custom fitness platforms where workflows match how your business operates, with the flexibility to change with your needs.
Traditional fitness software gives every gym and studio the same screens and flows, so your member experience looks like your competitors'. We build custom fitness software solutions tailored to your brand and member expectations.
Many fitness apps are created to serve thousands of clubs at once. We build custom fitness apps, native and cross-platform, that perform on every device and ship on your schedule.
Memberships, retail, bookings, and content often live in separate systems. We create connected fitness ecosystems where purchasing, scheduling, and engagement support each other and the user.
Legacy systems control access to data, which is often fragmented across systems. We build unified fitness platforms that give you control over your data so you can layer intelligence on top of it.
One-to-many offers are no longer enough. We build custom fitness apps and systems that empower you to engage with members and users one-to-one.
Members use many modalities to interact with a fitness brand. Web, mobile, apps, wearables, social media, scheduling systems. We build truly intelligent connected fitness ecosystems, enabling you to leverage every interaction channel.
A workout on the floor and a workout in an app are tracked separately, if at all. We build connected fitness platforms that link equipment, wearables, and mobile so every session counts toward one member profile, in the club or at home.
Hardware alone competes on price and specs that rivals match within a product cycle. We build the embedded software layer, apps, cloud services, and connected experiences that turn a machine into a platform customers choose and operators depend on.
Members expect to tap a wearable, start a machine, and see results in the app without pairing, logins, or dropped connections. We build the firmware, Bluetooth, and cloud integration that make equipment, wearables, and mobile work as one system.
Future of Fitness: Winning with Digital Value Creation
The fitness industry is shifting toward digitization
Work with AKTIV to turn this shift toward connected digital fitness experiences into a competitive advantage.
AI-native engineering has changed the math on build-versus-buy. Custom software that once required a large capital project can now be built in weeks at a fraction of the cost, enabling fitness operators to rent commodity systems and custom-build the experiences that differentiate their brand.
The line between a gym visit, a home workout, and a wearable session is disappearing for members, even when it still exists in the operator’s systems. Brands that connect equipment, fitness apps, and devices into one member record own the full relationship; brands that don’t see only fragments of it.
Members compare your fitness app to the consumer apps they use daily, not to other gyms. Meeting that standard requires owning the mobile experience and designing for how your members train rather than accepting a vendor’s version of it.
Sleep, recovery, nutrition, and stress now sit alongside workouts in how members think about progress. Digital fitness platforms that integrate wearable and wellness data with training become the daily destination; platforms limited to class schedules and check-ins become one app among many.
We live what we build
Our people train in gyms, use the equipment, and wear the devices we build software for.
We are not learning the industry from a requirements document.
We understand the member experience because we live it ourselves.
We know why members churn, why equipment data matters, and why a front desk workflow breaks down at 6am.
The world’s leading fitness brands trust us.

Case Studies
Our approach
With little formal documentation to lean on, Coherent’s team relied on frequent, direct conversations with the client’s technical staff to confirm new features as they completed each step of the project:
- Codebase archaeology and consolidation: engineers worked through the four mismatched mobile repositories, cross-referenced them against the live app store build, and reconstructed the most current working codebase before making any changes.
- Environment separation: introduced dedicated development, QA, and production environments in place of the single, undifferentiated setup the client had been running.
- Cloud infrastructure cleanup: rebuilt cloud build pipelines and restructured infrastructure, improving reliability, while bringing monthly cloud costs down from roughly $8,000 to about $1,500, an 81% reduction.
- New device API: built a new backend API, on a Grails and Java/Spring stack, that takes raw measurements from the client's new refraction-testing hardware, applies the client's formula, and returns validated results ready for review by a licensed doctor.
The solution
Today, the platform supports a complete at-home vision-testing workflow. Users complete a guided assessment with the client's hardware, results are processed through Coherent-built backend logic, and outcomes are routed to a licensed eye care professional for a prescription. The underlying infrastructure now runs across separate dev, QA, and production environments at a fraction of its previous cloud cost, giving the client a stable foundation to build on as it brings new devices to market.
The impact
- 81% reduction in monthly cloud costs, from about $8,000 to about $1,500
- New device API delivered in about 9 months, supporting the client's newest hardware line
- New development, QA, and production environments to replace the client’s single setup, consolidating four mismatched mobile repositories into one working codebase
The challenge
An undocumented, fragmented codebase
Before building the API or writing new code, Coherent needed to identify the code currently driving the client’s companion app. With no product requirements documentation and four mismatched repositories to sort through, they had to cross-reference what was on old developer laptops against the live versions in the app stores.
No environment separation and rising cloud costs
The client’s systems and software were running in a single environment — without a clear separation between development, QA, and production — which increased the likelihood of issues like cascading errors. Additionally, cloud infrastructure spend was disproportionate to the size of the product, running close to $8,000 per month.
New hardware, new math
The client was bringing a new device to market that paired with the user’s smartphone and measured refractive error using patented optical technology. Coherent needed to build the backend logic that would take the client's proprietary formula, apply it to raw device measurements, and return an accurate, prescription-ready result.

Coherent Solutions joined the project after the proof-of-concept stage, partnering with the client’s teams to expand the foundation into a scalable production solution. The engagement followed a mixed-team model and combined Coherent engineers, client developers, and U.S. contractors under one delivery stream.
The teams worked in close coordination, sharing ownership of delivery and ensuring the new platform aligned with the client’s broader membership systems. Early milestones focused on corporate training programs for all members, followed by the introduction of personal coaching and trainer management features.
One of the most significant challenges was onboarding coaches who already had established workflows on the previous system. The new platform needed to deliver significant improvements in usability and value to ensure a smooth transition and sustained adoption.
Development decisions were guided by collaboration and pragmatism. While each release built toward a stable foundation that could support future innovation without creating technical debt.

The new coaching system was built directly within the client’s flagship fitness app, eliminating the dependency on third-party tools. The platform introduced a library-based content structure that gave trainers a simple way to create, reuse, and personalize content for members. Coaches can also assign workouts to individuals or publish broader programs for open access.
The platform also centralized trainer bios and profiles, which were previously hosted externally. Coaches now manage their professional details and content in one environment, simplifying oversight and improving data consistency.
A key milestone involved designing a seamless data and services migration that minimized downtime and prevented data loss. Though separate from the coaching rollout, this work advanced the client’s modernization goals by replacing high-cost, inflexible storage systems with a more efficient infrastructure. The resulting framework became a repeatable model for future migrations across the client’s digital ecosystem.
The architecture also gave internal teams more freedom to extend the platform. New features could be developed and deployed without disrupting live services, allowing the client to evolve functionality as its digital strategy advanced.
The impact
The integrated solution transformed the daily experience for both coaches and members. Coaching now lives entirely within the flagship app, creating a seamless, branded environment and reducing operational complexity.
The result is a more consistent experience, stronger retention, and clearer pathways for future digital expansion.
The client realized digital value across multiple areas, including:
-
Reduced ongoing costs and removed reliance on third-party licensing.
-
Full ownership of platform data and content.
-
Unified corporate and personal coaching within the main app.
-
Approximately 2,000 trainers can deliver and digitally manage their programs.
-
Centralized trainer profiles and content within a single environment.
-
Improved visibility and discoverability of coaching programs for members.
Integrating coaching into the unified app also strengthened the client’s broader engagement ecosystem. Members now move easily between training, educational content, and wellness features. They can read blog posts, track their habits, and explore lifestyle tips all within the same experience. The app also supports related business lines such as spa services, supplements, and café sales, turning member engagement directly into revenue growth.
The platform now serves as both an operational backbone and a launchpad for upcoming digital initiatives.

The challenge
The original coaching model relied on a third-party platform that required members to install a separate app and manage another login. The setup created friction, diluted the client’s brand experience, and carried recurring licensing costs.
For coaches, managing programs, profiles, and client sessions across multiple systems slowed workflows and reduced visibility. The client wanted a single, cohesive environment that gave trainers more autonomy and allowed members to access all coaching content in one place.
Beyond these immediate concerns, vendor dependence also limited the client’s ability to adapt or extend features.
After reviewing available third-party options, the teams concluded that none could meet the performance and integration goals. As Coherent Solutions Software Engineer Siarhei Karabko explained, “building a native platform became the logical path forward.” It would provide support for both personal training and corporate wellness programs within one environment that existing vendors couldn’t offer.”
The project became a key step in the client’s wider modernization plan to consolidate core member experiences and reduce vendor dependence across its digital ecosystem.
What’s next
The coaching initiative continues to evolve with new staff applications and deeper feature sets. Current priorities include better data management, personalized training flows, and enhanced hybrid engagement that bridges digital and in-club experiences.
As the client expands its digital membership strategy, the integrated coaching platform remains central to its vision for connected fitness and long-term digital growth.

Ready to build something people use every day?
Whether you want to launch a new product, scale an existing platform, or recover legacy technical debt, let’s talk about what’s actually blocking you.
Relevant
Questions
When your member experience, programming, or operations differ enough from the vendor’s template that workarounds cost more than building. Commodity functions like billing and scheduling can stay rented while the member-facing layer is built to your brand.
Routine development, testing, and documentation are handled by AI agents under human review, significantly reducing the time and cost of a custom build. Projects that once justified a vendor platform on cost alone now justify building what differentiates the brand.
Release control, native performance on the device, integration with your equipment and wearables, and a design built around how your members train. White-label apps serve thousands of clubs, which limits all four.
Through each vendor’s SDK and health APIs, with pairing, sync, and reconnection tested on physical devices. Most wearable integrations fail on edge cases like dropped connections and background sync, which is where engineering depth matters.
Hardware margins compress as competitors match specs, while software creates recurring revenue, a direct relationship with the end user, and data that improves the product. The machine becomes the entry point to a platform rather than the whole sale.
Churn prediction from attendance patterns, personalized programming from wearable and equipment data, automated member outreach, and demand forecasting for classes and staffing. Each depends on having clean, connected data first.
