The Challenge
What made it hard.
Logging happens dozens of times a day, often mid-conversation. Anything slower than a single tap breaks the habit loop — and the data is sensitive health behaviour.
Our Approach
How we built it.
One-tap logging from the widget and lock screen, local-first storage with encrypted sync, and an adaptive plan engine that recalculates targets from real behaviour.
