Aim Trainer

Welcome to Computer Forums.

Not sure if this is a genuine question or a set up for spam so apologies if I have misjudged your post but I'd say simply practice and using decent hardware i.e keyboard/mouse. Most of these types of games use some form of anticheat these days so you've little chance of using a 3rd party tool and anything being advertised as such is likely either malware and/or a scam and therefore best avoided.
