What is a 3D aim trainer?

A 3D aim trainer renders targets in a real 3D environment — you aim at bodies with volume, move your crosshair in full 360°, and deal with distance, elevation, and movement just like in an actual FPS. It is a category above 2D click trainers for real transfer.

The tradeoff: 3D trainers need a GPU, are heavier to load, and use more CPU. 2D trainers load in a second and work on any device.

Why train in 3D at all?

Modern FPS aim is not just clicking a point. It is:

Keeping your crosshair at head height across 3D space
Compensating for perspective — a head at 30 m is smaller than a head at 10 m
Tracking a target through strafes, jumps, crouches
Managing recoil climb while continuing to lead a moving target

None of that is captured by clicking circles on a flat canvas. 3D is where real aim improvement happens.

Our 3D aim trainer — FPSTrain

FPSTrain is our in-house 3D aim trainer. It runs on Three.js in any modern browser, supports WebGL 2.0, and ships 13 training modes tuned to the five FPS aim archetypes: flick, track, switch, micro, reflex.

Human-shaped targets

Not floating circles. Humanoid dummies with chest, head and headshot zones — the same geometry you aim at in Valorant or CS2.

Recoil simulation

AK, M4, Vandal, Phantom and more recoil patterns per-game so your spray control transfers.

Game presets

Exact FOV values (Valorant 103°, CS2 90°, Fortnite 80°, Apex 104°) plus sensitivity scaling so training does not waste input reps.

13 curated modes

Grid Shot, Flick Shot, Micro Shot, Smooth Track, Reactive Track, Strafe Track, Target Switch, Multi Kill, Headshot Only, Peek & Fire, Sniper Training, Spider Shot, plus a freeform warm-up.

Which should I use — 2D or 3D?

2D (FPSAim) for 5-minute warm-ups, weak / older hardware, mobile, Chromebooks, or when you just want to click things fast.
3D (FPSTrain) for serious practice that transfers to ranked matches — tracking strafers, headshot-only drills, recoil control.
Both for daily training: 2D as a 60-second warm-up, 3D for the actual session.

How does FPSTrain compare to Kovaak and Aim Lab?

Kovaak is a 3D trainer too, but it is paid ($9.99 on Steam, Windows-only). Aim Lab is free on Steam but requires a 2 GB install and an account. FPSTrain is the only mainstream option that is free, browser-based, cross-platform, and needs no account.

System requirements

Any modern browser with WebGL 2.0 (Chrome, Firefox, Edge, Safari, Brave, Arc — all recent versions)
Integrated GPU is enough for 60 fps at medium quality
Mouse strongly recommended — touch works but is not ideal for aim training

FAQ

Is this 3D aim trainer really free?

Yes. 100% free, no account, no Steam, no download. Everything is in the browser.

Does 3D training really help more than 2D?

For muscle-memory transfer to actual FPS matches, yes. 2D is great for click-speed and reaction time; 3D is where crosshair placement and tracking grow.

Can I match my exact in-game sensitivity?

Yes — game presets for Valorant, CS2, Fortnite, Apex and Overwatch include the correct sensitivity scaling per game.

What if my computer is slow?

Use the 2D trainer — it runs on anything with a browser.

Why two sites?

Different use cases. FPSAim loads in one second for quick warm-ups on any device; FPSTrain gives serious 3D training for home practice.
