Lights Out Reaction Timer

Lights Out is a mobile-first reaction training app built with Next.js and TypeScript.
It focuses on speed, consistency, and race-start discipline through two F1-inspired drills:

• Start Lights: react to a five-light launch sequence without false-starting.
• Tap Sequence: complete a 10-second active-light challenge with fast, accurate taps.

Each mode tracks performance telemetry such as best time, rolling averages, and session totals, then stores results in local storage so progress is preserved between visits.
The app is also shipped as a Progressive Web App, which means it can be added to a home screen and used with basic offline support after the first load.

I built this project as a focused, game-like way to train reaction speed while practicing responsive UI design, timing logic, and real-time feedback patterns.
