Internet Reaction Challenge

A quick challenge that feels like a game — but it gives real insight. We measure your reaction, then estimate how much network delay your internet adds.

Result

Press Start. When the stage turns GREEN, tap as fast as you can.

Why this is useful

  • Reaction time is you (your reflexes).
  • Internet delay is what your connection adds (rough estimate from real pings).
  • Jitter is instability (spikes feel like “micro-lag”).

For best context, run the speed test too.
