Hey Product Hunt 👋 I built PSA Calculator as a small, focused tool for FPS players who want a more structured way to find their mouse sensitivity. Instead of guessing a “perfect” number, the tool walks you through the PSA Method: • Start with your current in-game sensitivity • Compare a lower and a higher value each round • Choose the one that feels more controllable • Repeat until you get a practical sensitivity baseline It currently works well for games like Valorant, CS2, Apex Legends, Overwatch 2, Fortnite, and other shooters where you can manually adjust mouse sensitivity. Why I built it: Most sensitivity tools either convert values between games or calculate eDPI. Those are useful, but they do not help when a player simply asks: “What sensitivity actually feels right for me?” PSA Calculator is meant to answer that with a repeatable test flow. I’d love feedback from FPS players, aim trainers, and anyone who has struggled with sensitivity settings: What would make this more useful for your own setup?
