It's only fair to note what Aim400kg does do:
It is the "dumbbell" of aim trainers—it’s just a heavy piece of iron that does one job. It isn't a smart gym machine that tracks your heart rate and suggests a diet (like Aim Lab), but it builds muscle just as well if you put in the work. aim400kg
: A 2024 study published in Applied Sciences used Aim400kg to determine if mouse grip (palm, claw, or fingertip) changed performance. While claw grips showed different trajectory patterns in flicking, the research concluded that grip type ultimately does not significantly impact overall tracking or flicking accuracy.

While 3D trainers like Aim Lab or Kovaak's offer better graphics, Aim400kg’s 2D environment removes the "noise" of 3D depth and perspective. This allows you to isolate your in its purest form. It is particularly effective for improving "click-timing"—the fundamental skill of clicking at the exact microsecond your crosshair overlaps a target. While claw grips showed different trajectory patterns in
is a fantastic, free resource for developing raw mouse control and technique. It strips away the gaming gimmicks to focus on pure biomechanics. However, it feels dated compared to modern trainers like Aim Lab or KovaaK’s, lacking modern visuals, a large community, and advanced analytics.
Aim400kg is a free, web-based aim training website. Unlike its resource-heavy competitors, Aim400kg runs entirely in a browser using HTML5 and JavaScript (previously Flash). It is minimalist in design but robust in function, offering dozens of small, focused mini-games designed to test and improve specific aspects of mouse control: reaction time, clicking accuracy, tracking, and hand steadiness.
