Perfect Throw for Pokemon GO places an overlay over the screen shaped specifically to help guide your swipe while also allowing interaction with other vital parts of the screen. Use the floating toggle button to show/hide the overlay.
The blacked out portion of the overlay disables touches to prevent all inaccurate swipes when playing Pokemon GO. This majorly improves accuracy and prevents wasting balls.
