A reactive habit-tracking companion designed for zero-latency interaction. By leveraging a local-first architecture, it eliminates the 'loading spinner' fatigue common in wellness apps, fostering consistency through instant gratification.
Tech Stack
The Challenge
Traditional habit trackers suffer from 'network lag'—waiting for a server to confirm you drank water kills the dopamine hit. The challenge was to make a cloud-synced app feel as fast as a local notepad.
Reactive Data Layer
Built on Convex's push-based architecture. Data changes on the server push updates to the client instantly via WebSockets, removing the need for manual re-fetching.
The Solution
I implemented a strictly Optimistic UI strategy using Convex Mutations. The state creates a temporary 'success' reality for the user immediately, while the actual data synchronization happens invisibly in the background, ensuring 60fps fluidity.
Optimistic UI Patterns
User actions (like checking off a habit) are reflected instantly on the screen before the server confirms, creating a 'local-first' sensation of zero latency.
Gamified Momentum
A dynamic streak system visualized with Lottie animations and canvas-confetti triggers to scientifically reinforce positive behavior loops.
