Pulse (2026)
A cross-platform habit and fitness tracker built in React Native — offline-first, gesture-driven, and fast enough to use on the train.

— The Challenge
What needed
solving.
Pulse wanted one app for habits and workouts that felt instant and worked on the train with no signal — without building twice for iOS and Android.
Existing trackers felt heavy and online-only, breaking the moment connectivity dropped.
— The Approach
How I
built it.
I built Pulse in React Native with an offline-first local store that syncs when a connection returns, so logging never blocks on the network.
Gesture-driven interactions and 60fps animations make daily logging feel quick and genuinely satisfying.
