Why this site has two kinds of tools
This site started as a set of reflex and reaction tools for gamers, and has grown to include everyday calculators people search for constantly — GPA, percentages, age, and BMI. Both sides of the site share the same goal: fast, free, no-nonsense tools that do one thing well without needing an account or a download.
Which test should I try first?
If you're not sure, start with the Click Speed Test — it's the most common benchmark and the easiest to compare against typical scores.
Do these tests work on mobile?
The Click Speed Test, Reaction Time Test, and Aim Trainer all work with taps on a phone or tablet. The Spacebar Counter needs a physical keyboard, so it's built for desktop.
Are my results saved?
Not yet — each tool currently shows your result for that session only. Refreshing or leaving the page resets it.
