CASE STUDY / HYDROW / CONNECTED FITNESS

The Mobile Engine Behind Hydrow’s Real‑Time Connected Strength Platform

With a fast‑growing connected fitness platform and an aggressive roadmap, Hydrow needed senior engineers who could ramp quickly and own production‑grade architecture. BetterEngineer embedded senior mobile talent so Hydrow could launch a seamless strength experience that connects hardware, coaches, and members in real time.

About the Product
Lyquid: A Connected Strength Platform, Not Just an App

Lyquid is Hydrow’s new connected strength platform, a combination of smart hardware, real‑time adaptive resistance, and coach‑led strength programming that turns any room into a full, guided weight room.

The mobile experience is the connective layer: it’s how members discover strength programs, sync with Lyquid hardware, see real‑time resistance feedback, and track their progress over time, so every rep and coaching cue feels like one continuous system, on or off the machine.

For Hydrow, that meant building a mobile experience that could keep up with:

  • Real‑time resistance adjustments from the machine
  • Rich coaching content and movement libraries
  • Members switching devices and modes without friction

BetterEngineer helped Hydrow's team turn this vision into a scalable, production-ready mobile platform that connects all the pieces.

"What stood out was how well BetterEngineer's engineers integrated with our core team rather than operating as a separate group. They reviewed code, flagged issues early, and kept up with our pace. Scaling was the easiest part: one conversation, and we had a new engineer ramped and contributing faster than we expected."

The Summary
Building a Future‑Ready Connected Strength Platform

Hydrow needed the Lyquid mobile experience to feel like the brain of its new strength system, coordinating hardware, resistance, video, and coaching in real time. Any lag, crash, or UX seam would break the illusion of “a full weight room, reimagined.”

BetterEngineer embedded senior mobile engineers across Hydrow’s teams to:

  • Architect a mobile layer that could reliably orchestrate core workout functionality, content, and user data
  • Ship core Lyquid workflows such as session discovery, device pairing, in‑workout guidance, and progress tracking on an aggressive launch timeline
  • Set up the app for ongoing expansion as Hydrow adds new trainers, movements, and strength formats

Hydrow launched Lyquid with a mobile experience robust enough for a new connected strength product line and adaptable enough to support ongoing growth, powered by BetterEngineer’s embedded mobile developers.

The Challenge
Delivering a Cohesive Hardware and Mobile Strength Experience at Scale

Lyquid is more complex than a typical fitness app. It has to pair securely with smart hardware, respond to real‑time resistance changes without stutter, surface the right coaching and movement guidance, and keep members’ strength history in sync across devices.

Hydrow’s teams were already pushing hard on hardware, content, and platform services, so the mobile layer had to keep up without becoming a bottleneck.

That translated into four concrete challenges:

  • Build and maintain the Lyquid mobile experience with production‑grade architecture in Jetpack Compose and Kotlin, while keeping it extensible to other Hydrow apps.

  • Ship and test features that relied on physical hardware interactions.

  • Establish reusable infrastructure so new strength formats and product changes wouldn’t require rebuilding core components.

  • Ramp external engineers fast enough that they could be productive within two weeks and contribute end-to-end, from UI and business logic to API integration, under Hydrow's engineering leadership.

The Solution 
Hands-On Senior Talent, Embedded in Hydrow's Engineering Team

BetterEngineer staffed a blended team of senior Android engineers directly into Hydrow's existing teams, reporting to Hydrow's engineering leadership throughout. Instead of a separate offshore team, our engineers worked side by side with Hydrow's product, hardware, and content groups.

We applied our strict vetting process, selecting developers who had already tackled similar mobile challenges: complex state management, real‑time data, and integrations with hardware or other external systems. Hydrow wasn't onboarding generic staff augmentation; they were adding seniors who could ramp quickly and contribute to critical flows from day one.

Together, we:

  • Designed and implemented the device pairing and onboarding flows that connect the Lyquid hardware to the app in just a few steps

  • Built in‑workout interfaces that visualize real‑time adaptive resistance and keep members focused on form instead of fiddling with controls

  • Optimized performance so the app can handle rich media and hardware signals without lag or dropped sessions

  • Established mobile development patterns and testing practices that make it easier for Hydrow to ship new strength programs, movements, and features safely

Hydrow’s teams kept control of the product vision. BetterEngineer made sure the mobile layer was solid enough to bring that vision to life.

"I built the integration module that connects Lyquid, Rowing, and the Companion app to our music provider. Instead of three separate implementations, it's one shared piece that other teams can build on, and if Hydrow ever needs to switch providers, that change happens in one place instead of three. That's the kind of work I like most."
