Whether you're a new player dialing in your first setup or a veteran rebuilding muscle memory after a mouse upgrade, the fastest path to better aim is measurement. Instead of guessing, use an eDPI calculator to compress your DPI and sensitivity into one comparable number, or convert your whole config across titles with the sensitivity converter so every game feels identical.
Monitor and peripherals matter just as much as settings. A PPI calculator tells you your true pixel density, the FPS to refresh rate calculator shows whether your frame pacing matches your display, and the bottleneck estimator pinpoints where your upgrade money should go. For fine-tuning visuals, the crosshair generator builds and exports codes for CS2, Valorant and Fortnite.
Browser-only by design
Every tool here runs 100% client-side in JavaScript. No account, no upload, no data leaves your device, and nothing waits on a server round trip — formulas execute in milliseconds. That means tools stay fast and free forever.
Fresh tools keep coming
The library grows steadily, from Steam account math to Minecraft coordinate conversion to a random game picker for "what do I play tonight?" indecision. If a calculator is missing, suggest it — new tools ship regularly.
