As answered by people managing Brain Workshop and PickTests.
PickTests's answer:
PickTests started as a small independent project built one browser test at a time.
The goal was to create focused online tests that load quickly, are easy to understand, and do not require an account. After the first few tests were released, the project gradually expanded into a collection covering reaction time, memory, attention, aiming, and visual tracking.
The current focus is not only adding more tests, but also improving the existing experience, including mobile interactions, result pages, and local progress tracking.
PickTests's answer:
PickTests is built with:
The website does not currently use a frontend framework, backend account system, or database. Each test runs directly in the browser.
PickTests's answer:
PickTests keeps online ability tests simple and easy to access. Users can start immediately without creating an account, installing anything, or going through a long setup process.
Each test focuses on one clear task, with straightforward results and a design that works on both desktop and mobile browsers. Where useful, recent scores and personal bests are stored locally in the browser.
PickTests's answer:
PickTests is mainly for students, gamers, curious web users, and anyone who wants to test their reaction time, memory, focus, attention, or aiming skills.
It is also useful for people who want a quick personal benchmark and would like to repeat a test later to compare their own results.
PickTests's answer:
PickTests is a good choice for people who want a quick, free test without creating an account or navigating a complex training platform.
The website focuses on lightweight browser-based tests, clear results, and fast repeat attempts. It is designed for casual users who want to check their reaction time, memory, attention, or aiming skills without unnecessary steps.
