The Yo-Yo Intermittent Test evaluates one's stamina using a profile similar to sports like soccer basketball and other similar "stop-and-go" vigorous sports.

This app will allow you to conduct the following:
* The Yo-Yo Intermittent Recovery Test Level 1 and Level 2
* The Yo-Yo Intermittent Endurance Test Level 1 and Level 2

as defined by Jens Bangsbo of Copenhagen University (December 1994)

It will
- prompt you with voice cues or ringtones that you select
- display seconds to shuttle halfway point
- display seconds to next speed level
- display seconds during recovery
- display distance covered (incl. shuttles) and time elapsed

When you are done the app will provide you with
- the Level reached
- total distance run

Note: A rough estimate of VO2Max will be provided for Recovery Level 1 only provided at least 1000m (level 15.6) has been run.

This app will NOT allow you to directly save your results (the Pro version will); you could take a screenshot (power + lower volume buttons simultaneously).
