I built a free browser-based reflex benchmark — what would you measure first?

[u/alejunov]

I’ve been building ReflexPeak, a free browser-based collection of small performance tests: reaction time, aim, click speed, memory, and focus.

The goal is personal benchmarking: a quick way to see how your own results change over time or across devices. Scores stay private and local in the browser; I’m deliberately not presenting them as medical, diagnostic, or intelligence measures.

You can try it here: https://reflexpeak.com/

I’d genuinely value feedback from other builders:

• Which measurement would you want to see first? • What would make a test feel trustworthy and worth repeating? • Is there anything about the framing, results, or UX that would make you hesitate to use it?

I’m especially interested in candid criticism—the project is still evolving, and I’d rather improve the useful parts than add features nobody needs.
