CS2 Practice is a free browser-based aim training tool for FPS gamers. Train your aim with three core modes — Gridshot for reaction time, Tracking for mouse control, and Flicking for snap accuracy — all synced to your exact CS2 or Valorant sensitivity settings. Features include a database of 30+ pro player settings (s1mple, ZywOo, donk, NiKo), 100+ crosshair codes with one-click copy, a sensitivity converter across CS2/Valorant/Apex/OW2, and aim improvement guides. All training data stays local in your browser — no account needed, no data uploaded. Open the page, pick a mode, train. That's it.
