As someone who just hit immo on valorant this act (38HS%), I can credit a lot of my improvement to aimlabs. I have about 66 hours currently and have been training 3-5 times a week for 20-40 minutes. I like aimlabs because it allows me to get reps on certain aim mechanics I need in game but can't really practice anywhere else. The UI is pretty intuitive and allows you to easily select a task and understand your score in it. I recommend aimlabs to anyone serious about improving their aim. As for tasks, I recommend Charla7an's raw mechanics playlist for anyone looking to improve their mechanical aim (Flicking, tracking, reaction time).
