Found a bug, spotted a number that looks off, want to use the test in a class or an article, or just have an idea? Email me. I read everything.

The fastest way to reach ReactScore is email:
I usually reply within a couple of days. A few things that genuinely help when you write in:
- Bug reports: tell me your browser, your device, and roughly what your display refresh rate is (the test shows it). Reaction tools are fiddly and details matter.
- Corrections: if a statistic or claim looks wrong, point me at the source you trust. I would rather fix it than defend it.
- Press & data: happy to share our aggregate reaction-time figures and to comment on reaction-time stories. The headline numbers live on the average reaction time page.
- Embedding the test: teachers, gaming sites and writers are welcome to use it. Drop me a line and I will point you to the widget.
ReactScore is an independent project. There is no call centre and no chatbot on the other end, just me, so a human reply might take a day or two.
