Simple, non-intrusive and highly accurate, the app follows either the original Leger protocol (1984) or the most popular alternative.

All you need is
- a pair of running shoes
- a flat 20 meter running pitch
- a modicum of enthusiasm
- this app

Note: this is NOT a GPS-enabled app; rather, it's a timer app that let's you easily conduct the beep test.

No ads, no tracking, no special permissions. It
- prompts you with beeps
- displays shuttle and level visual cues
- displays distance covered and time elapsed
- allows for a 15m or 20m lap
- offers an auto stop feature

When you are done, the app will estimate your vo2Max

... that will
- give you bragging rights (hopefully)
- allow you to compare your fitness to that of the general population
- allow you to chart your progress

Caution : Some side effects have been noticed
- Runner's high. You will find yourself smiling far too much
- Fitter. Regularly done, you will be able to 'run up those stairs'
- Leaner. Darn, gotta buy smaller jeans!

Note: your result(s) will NOT be stored by the app; take a screenshot of the results page if you like.
