The challenge
Pulse Labs had funding, a hypothesis and a deadline: a working habit-and-sleep tracker in the App Store within one quarter, polished enough to support a seed-round demo.
The approach
Scope discipline was everything. We cut the feature list to a single core loop — log, streak, insight — and I designed and built it in React Native with a shared design-token system so future platform work wouldn't require a redesign.
The outcome
Shipped in ten weeks. The demo helped close the seed round, and week-four retention beat the benchmark the founders had promised investors.
