Prop the phone up, take guard, and play each ball as it is called. Every bowler type, every shot, scored like a net session.
Tap only what went wrong. D = wrong shot for the ball. B = base or head moved at contact. F = lost the finish. OUT = a swing that gets you bowled or caught.
Targets: decision 90% or better, and no more than 1 dismissal per 30 balls. Settings, coverage and history are saved on this phone only. Shadow work builds the pattern; hit real balls at least twice a week to turn it into runs.
