PickTests is a collection of lightweight browser-based tests built around simple interactions, clear results, and the idea of comparing your own performance over time.
The project started with a reaction time test and gradually expanded into a small collection of tests covering reaction speed, memory, attention, aiming, and visual tracking. Each test is designed to be easy to understand: open the page, follow a short instruction, complete the test, and get a result within a few moments.
The current collection includes:
- Reaction Time Test — measure how quickly you respond to a visual signal, with single-round and five-round modes.
- Aim Trainer — test speed and precision by clicking or tapping targets as they appear.
- Sequence Memory Test — remember and reproduce increasingly longer visual sequences.
- Number Memory Test — remember numbers using classic, reverse, and one-by-one modes.
- Multiple Object Tracking — follow several moving targets while ignoring other objects.
- Stroop Test — respond to colors and changing rules while dealing with conflicting visual information.
PickTests runs directly in the browser. There is no account to create and nothing to download. The tests work on desktop and mobile devices, and some of them keep recent results and personal bests locally in the browser so you can return later and compare your scores.
The goal is to keep the experience lightweight and straightforward rather than turn each test into a complicated training system. Pick a test, see how you do, and try it again when you feel like beating your previous result.
