Questions people ask

Clear answers and limits

Does the trainer work on touch screens?

Yes. Target mode and tracking position work with touch or pen without requiring pointer lock.

What does pointer lock change?

It hides and confines the pointer while reporting relative movement, useful for desktop tracking. Browser and operating-system support varies.

Why does a hidden tab end the session?

Background throttling would make timing misleading, so the tool ends the attempt honestly.

Can results be compared across devices?

Only cautiously. Display refresh, scaling, pointer settings, hardware, and browser scheduling can all change results.

Is this a reaction-time medical test?

No. It is a practice game with local session metrics only.
