WJR Trainer

WJR Trainer is a simple soccer conditioning timer for Walk, Jog, Run drills. Use it to guide players as they move between endlines, sidelines, cones, or marked field distances. The app runs a continuous timer and clearly signals each pace change with full-screen colors, large text, and soccer-style whistle sounds. For each minute: Walk from 0 to 29 seconds. Jog from 30 to 49 seconds. Run from 50 to 59 seconds. Coaches can customize whistle tones, enable an optional end timer, and choose which timer is shown largest during training.
