About

Ghost Squash

Features
Read full description

Ghost training — moving to every corner of the court without the ball — is one of the most effective solo drills in squash. Ghost Squash turns it into a guided, trackable workout for any level. • 10 court positions — most ghost drills use only six corners, which leaves the spaces in between untrained and grooves an incomplete movement pattern. Covering all ten trains the whole court, the way a real match demands. • Five training focuses — front, back, volley, fitness or balanced • Spoken cues guide you to every corner, even with the screen locked • Adjustable intervals, sets and rest periods for any level • Randomised timing so you can't anticipate the rhythm • Per-position movement instructions for correct footwork • Track your progress with a weekly chart and streak • Session card — share your workout as a visual card and challenge your squash friends No account needed. Your training data stays on your device. Who it's for: Squash players of any level who want to train alone — improving footwork, court coverage and conditioning without needing a partner.
