does what it promises, small bug in emailing results
It does exactly what it says… tells you how to take the test, counts down for you, runs a steady metronome during the 3 minute test, then 15 seconds later it asks for your heart rate. It calculate your v02max for you and you can tweet, email, or Facebook the result. I ran into a small bug - after emailing myself the results, I couldn't exit the email screen of the app. Small bug, otherwise happy with the app.
