What we build
Services for Fitness.

Machine learning analyzes user activity to deliver personalized fitness plans with real-time feedback. Predictive analytics for engagement and retention.
Gym & studio management software
Membership tracking, class scheduling, automated billing, CRM integration, and the operational workflows gyms actually run on. Pattern from our Metrostars Gym engagement.
Wearable & IoT integration
Apple Health, Google Fit, Fitbit, Apple Watch, Garmin, and other wearable platforms integrated for unified progress monitoring and data sync.
E-commerce & subscription platforms
Recurring billing for fitness programs, subscription workout plans, gift memberships, family plans, freeze-and-resume workflows.
AI chatbots & virtual assistants
24/7 customer support, member onboarding, and guidance through the fitness journey. Configurable per brand voice and program.
Adjacent OST experience
Fitness work lives alongside OST's Healthcare and Wellness practice.
Metrostars Gym is on our Healthcare and Wellness vertical page (member platforms and wellness work). Swing Your A Game (golf coaching app) is part of our broader sports and active-lifestyle engagement portfolio.

Fitness-sector compliance
Frameworks fitness clients ask about.
Compliance scoped per engagement. OST does not hold direct PCI-DSS or GDPR certification; we assist with implementation and route through compliant providers to minimize scope on your platform. See the Trust Center for the broader posture.
PCI DSS (assisted)
Membership billing routed through PCI-compliant processors to minimize cardholder data scope. We assist with implementation rather than holding direct PCI certification.
WCAG 2.2 AA + Section 508
Accessibility for fitness platforms. Required for federal grant recipients and increasingly demanded by ADA-related demand letters targeting member-facing platforms.
GDPR + CCPA (assisted)
Member PII handling for international and California users. Opt-in consent, right-to-delete workflows. Implementation assistance scoped per engagement.
App Store privacy disclosures
iOS HealthKit and Android Health data declarations done correctly. Privacy nutrition labels prepared for App Store and Google Play submission.
