About the product

Reaction Time Test is a free collection of browser-based reaction challenges. Respond to a color change, visual cue or sound, view response times in milliseconds, and compare your own attempts using results saved locally in your browser. No account is needed. It is for recreational use, not medical diagnosis or a scientific assessment; device, browser, display and input latency can affect the results.

For product owners

Promote Reaction Time Test

Every listing gets one post to our X and Threads followers. It is seen once, then the traffic stops. Promotion keeps Reaction Time Test in front of people instead.

  • Back in the X and Threads rotation: Reaction Time Test gets posted again instead of once.
  • A promoted slot on the AppRater homepage, carrying a Promoted badge.
  • A direct link to Reaction Time Test from a DR45 site (Ahrefs Domain Rating), with no redirect in between.
  • A labelled spot in the weekly email to AppRater subscribers, one promoted app per issue.
  • Stays on the first screen however old the listing is, while new submissions push everything else down.
