Going to do a quick review of aimlabs right now. This is just coming from the honest opinion of a pro gamer (the definition of a pro gamer is to possess high level skills not just be competitive in esports) and I must say its a very useful tool to have. Its a great utility to have to warmup before playing your favorite fps either solo or team deathmatch or free for all. One of the most important tools is the built-in sensitivity system. You select the game you want to play, enter your sensitivity, DPI and mess around with other settings, and train with a setup that matches your actual game.
What I actually like to do is implement probability chaos theory mathematics which will give me a rough estimate of where I'm at in say for examples sake best out of 5 matches. In Aimlabs this translates to however you want to tailor your aiming skills. Let me tell you one thing though, its no substitute for playing the real FPS game your playing. You need to learn more and you need to grow. This is success through baptism by fire. You've got to be really accepting of where you are now skill level wise. The biggest mistakes that a lot of people make or the majority is lieing to themselves, thinking they know it all. The absolute worst thing that you could possibly do to yourself and believe me this is a big one, is to start using cheats. You could be a great gamer all around but instead all I see on here are people that want cheat codes for their games. Going down that route you're only denying yourself the ability to get better.
Aimlabs also provides detailed statistics, heatmaps, performance trends, ranks, benchmarks and leaderboards. This makes it easier to understand where your improvements are and where you still need work. I could go on and on but you get the point. You want every advantage that you could possibly have without cheating in your games.
