The SIQ smart ball measures the initial angle in which you launch the ball when shooting.
Having a correct release angle is important as it determines the arc of your shot. Flat shots reduce your margin of error because of the low entry angle, while shots with too much arc are harder to control, as even the smallest errors in the release are magnified.
To work on your release angle during a shooting session, turn the phone to “SCOREBOARD MODE” (horizontal) and swipe left two times to the “RELEASE ANGLE” metric. Challenge yourself to take a certain number of shots within a precise release angle range (e.g., 55-60 degrees if shooting from 20 feet out) with as little variation as possible.
