The beep test, or 20-m shuttle run test, is a progressive aerobic cardiovascular endurance test employed by many international sporting teams. This app will lead you through a series of stages that have different tasks, used to estimate your VO2 max (maximum oxygen uptake)!

The pacer test involves running continuously between two points that are 20 meters apart from side to side. These runs are synchronised with the app, which plays beeps (whistles) at set intervals. As the test proceeds, the interval between each successive beep decreases, forcing the athlete to increase their speed over the course of the test, until it is impossible to keep in sync with the recording (or, on extremely rare occasions, until the athlete completes the test). It allowed to get one beep before the person makes the line, but if the person being tested does not make the next interval then the most recent level they completed is their final score. The test is typically structured into 21 'levels', each of which lasts around 62 seconds. The interval of beeps is calculated as requiring a speed at the start of 8.5 km/h, increasing by 0.5 km/h with each level thereafter. The progression from one level to the next is signaled by 2 quick beeps. The highest level attained before failing to keep up is recorded as the score for that test.

Good but doesn’t save

I love using this app but it doesn’t save my previous tests. If I open the app right after my workout, the test is saved in My Tests, but when I come back a day later it’s no longer there. Could you please fix this bug?

Developer Response ,

Thank you for letting us know this bug, we will look into asap.
