Definition & Use in Games
A crosshair is the aiming reticle—usually a small cross, dot, or ring—centered on a screen to mark where actions or shots land. On desktops it is built into games; on phones it often is not.
Why mobile gamers add one
- Precision: a fixed center reference helps aim in shooters and FPS titles.
- Consistency: an overlay stays put regardless of in-game UI changes.
- Low distraction: a thin, adjustable reticle is easier to read than busy default markers.
How a crosshair overlay works
An app like CrossHair draws a transparent, always-on-top layer with a customizable crosshair (color, size, shape) that follows a fixed screen position. It does not touch the game—it simply renders a reference on top. Players tune opacity and offset so the reticle sits exactly where they want, then leave it running only while gaming.
