Coaching That Scales
Coralsoft designed, built and shipped this product for the client.
Caliber pairs a free, ad-free strength logger with access to certified human coaches — not AI. Its method is mastery over variety: repeat core lifts while progressively adding load and reps.

Caliber pairs a free, ad-free strength logger with access to certified human coaches — not AI. The main delivery challenge was to give users sensitive health information presented calmly, clearly, and without adding cognitive load, while keeping Onboard, Plan, and Train consistent across the complete journey. We framed the engagement around the smallest production-worthy flow first, then expanded the scope without weakening the underlying component and data model.
We began by mapping the user journey and the boundaries of the AI: what context it receives, what it may return, and where deterministic application logic must stay in control. We then built Onboard, Plan, and Train as small end-to-end slices, connecting the interface to the data and model layers early so the team could test real responses instead of static mock-ups. Streaming and real-time states were treated as first-class UI states, including loading, partial output, retries, and recovery. The main implementation used React Native, Expo SDK 54, Expo Router, and TypeScript, with typed contracts keeping the JavaScript stack consistent across the product.
The delivered scope brought Onboard, Plan, Train, and Review into one coherent cross-platform mobile release. Model output, product logic, and user feedback are separated clearly, which makes the AI easier to evaluate and evolve. For Caliber, the practical result is a product that communicates its value quickly while giving the team a maintainable base for continued delivery in health & wellness.
The bottleneck was never the workout — it was accountability that scales. Caliber puts a certified human behind the logger.
By making certified human coaching affordable and scalable, Caliber gave beginners real accountability and intermediates a way to break plateaus — without the price of an in-person trainer.
