Fitness & coaching web + mobile
FitTrack
A fitness and coaching platform delivered by PrimeStack Developers, bringing session planning, workout logging, meal journaling, progress review, and coach communication into a coordinated product.
PrimeStack — Client Project Implementation Screens use demonstration data. These web and mobile applications were custom-built, engineered, and deployed for our clients by PrimeStack.
The challenge
Make it easier to move from a chosen plan to a recorded session and a useful reflection, without forcing members and coaches to search across separate tools.
Business context
Developed by PrimeStack Developers for a health and fitness client, tracking active exercise loads, meal values, and facilitating real-time coaching conversations.
The proposed solution
The delivered implementation pairs a React web client with a React Native mobile application and NestJS backend services for cross-platform syncing.
Proposed architecture
- React / Vite / TypeScript web experience with dedicated screens for core workflows.
- React Native / TypeScript apps for iOS and Android, leveraging shared API contracts.
- NestJS / Node.js / TypeScript services for programs, exercises, session logs, member-created goals, journal entries, and coach relationships.
- MongoDB / Redis storage with explicit ownership, validation, and role-aware access checks.
- AWS / Docker deployment and media infrastructure, with production security and observability implemented.
- Implemented health-data permissions, coaching qualifications, device integrations, offline sync behavior, and notification delivery.
Workflows illustrated
- Training overview: Your plan, your activity, and the next session in one place.
