Circadian Productivity

Peaks transforms sleep data into an energy forecast. It predicts when you peak, dip, and recover — and turns that into a planned day of focus, exercise, and rest.

Peaks transforms sleep data into an energy forecast. The main delivery challenge was to give users sensitive health information presented calmly, clearly, and without adding cognitive load, while keeping Track, Model, and Forecast 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 Track, Model, and Forecast 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. Prompt, validation, and fallback behaviour were refined alongside the product UI. 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 Track, Model, Forecast, and Plan 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 Peaks, the practical result is a product that communicates its value quickly while giving the team a maintainable base for continued delivery in health & wellness.
Productivity comes from working with your rhythm — not against it. Sleep is the input. The plan is the output.
By transforming passive sleep tracking into an active daily plan, Peaks turned circadian science into practical productivity — and gave busy users a calmer, more aligned day.
