Health Tech

Coach Welly is an AI-powered wellness engagement platform for gyms, corporates, and insurers. Members connect wearables (Fitbit, Garmin, WHOOP, Apple Health, Google Fit) and earn points for healthy activity.

The Challenge

Slowed by their legacy app build and restricted to iOS, Coach Welly needed an uplift to support Android parity, frictionless subscriptions and referrals, and dependable wearable data fast to unlock growth.

Pain points

  • No Android app meant capped reach and limited MAU.
  • No in-app subscriptions delayed revenue capture.
  • No referral loop restricted organic growth.
  • Wearable integrations were incomplete and inconsistent across devices.
  • Legacy frontend had low test coverage and slow iteration speed, increasing risk.

Business goals

  • Launch an Android app quickly to expand reach.
  • Grow MAU through true cross-platform coverage.
  • Enable seamless payments, referrals, and broader integrations.
  • Modernise the frontend to support AI-ready features.
  • Reduce technical debt and improve delivery velocity.

Cleer's Solution

Our delivery approach is simple: prioritise speed and design, delivering impact in days, not months.

  • We shipped an Android MVP in just four days and reached full parity with iOS within two weeks, closing platform gaps and unlocking acquisition immediately.

  • Payments were built to simply work, with App Store and Play Billing integrated for complete reliability.

  • We implemented a referral loop that offered dual-sided incentives while protecting against fraud.

  • Integrations with wearable technologies ensured customers steps, sleep, and heart data synced seamlessly, ensuring users activity data is real and reliable.

  • We built an event-driven backend designed for longevity: analytics-ready, privacy-aware, and structured for future AI coaching. With CI/CD pipelines, feature flags, and hardened quality in place, releases became routine rather than risky.

Delivery Engineering & Quality

  • Established CI/CD pipelines, feature flags, and environment parity.
