Lights Out Reaction Timer

Lights Out is a mobile reaction trainer built around two F1-inspired drills:

• Start Lights asks you to react to a five-light launch without jumping the start.
• Tap Sequence gives you ten seconds to hit each active light as quickly and accurately as possible.

Each mode records best time, rolling averages, and session totals in local storage. The app can be installed to a home screen and retains basic offline support after the first load.

It began as a small way to practise timing logic and immediate feedback. The result is simple enough to open for a few attempts without turning reaction training into another programme to manage.
