Super fun and easy to use! Human Benchmark is a great way to test your reaction time, memory, and focus in just a couple of minutes. I love that it’s free, browser-based, and doesn’t require any signup. Perfect for quick brain breaks or a little daily challenge.
Sixteen sub-two-minute tests with a global leaderboard and no signup is a great low-friction way to benchmark focus. Do you save scores over time so returning users can track progress?
As someone who teaches complete beginners to build their first web tools, this is exactly the pattern I point them to: one clear job, an instant result, and zero signup friction. The "every test under two minutes" constraint is a smart retention choice too. One genuine question — since the tests run in the browser, how do you keep the global leaderboard honest? Do you filter outliers, or is the ranking more for fun than a strict competitive board?
Clean concept and easy to understand. The interface looks simple, and it's great to see a free tool that's accessible without signup. Wishing you success with the launch and looking forward to future updates! 🚀
Really fun idea. The leaderboard makes it more engaging too. Nice launch!

I too have AI product, it's trending
Good look this is very good project)))
A classic — I've used the reaction-time test for years to gauge how tired I actually am. What would take it further: saving history over time, so you can see whether sleep or coffee actually moves the numbers. Does it track that yet? https://unicorgi.dk/
This is a good one. Can't wait to try it out
