YoYo Test Tracker

Run Yo-Yo tests with clear audio cues, circular shuttle timing, and ad-free progress analytics.

YoYo is a focused, free, ad-free app for running and tracking Yo-Yo fitness tests.

Start a timed Yo-Yo test with clear run and recovery cues, loud audio guidance, and simple on-screen commands. The app records the final level and shuttle, then calculates useful performance metrics such as distance, duration, estimated VO2max, estimated calories, and progress over time.

Built for athletes, coaches, teams, and fitness testing sessions, YoYo keeps the testing screen simple during the test and moves history, analytics, settings, and science notes into deeper pages.

Key features:

• Timed Yo-Yo test runner with run and recovery phases
• Loud beep and voice guidance
• Circular shuttle timer for active run intervals
• Simple recovery countdown
• Manual result entry when a coach calls out the final level and shuttle
• History table for past tests
• Analytics graphs for distance, VO2max, calories, duration, level, shuttle, and rating
• Athlete profile fields for better estimates
• Science notes explaining how the Yo-Yo test works
• Free and ad-free

Important note: VO2max and calorie values are estimates based on entered test performance and athlete profile data. They are not medical measurements.
