I can't hear the beeps

Turn up the phone's volume with the side buttons. On iPhone the beeps play even with the silent switch on, and the volume buttons set how loud they are.
If headphones or a Bluetooth speaker are connected, the sound goes there. Bluetooth speakers add a small constant delay to every beep, which does not change the intervals between them.
Music from other apps keeps playing underneath the beeps.

Keep playing with the screen locked

The test keeps going with the screen locked. On Android, the app shows a "Beep test running" notification while a test runs; Android needs it to keep playing with the screen off, so please don't force-stop the app during a test. On Android 13 and later it asks once for permission to show this notification; if you said no, the test still plays, you just won't see the notification.

Which test should I choose?

20 m shuttle run is the standard multistage test (Léger 1988): 8.5 km/h at the start, +0.5 km/h each level, 21 levels and 247 shuttles.
20 m, level 1 at 8.0 km/h is the UK and Australian version, a little gentler at the start.
15 m police style: levels 1 to 5 match the published UK 5.4 standard (35 shuttles, 525 m, 3:35). Above level 5 it follows the common audio, not an official table.
15 m school version is for short indoor spaces.

Mark out the exact distance, and use the same test each time if you want to compare results. Beep Test has no HAMR test mode: official Air Force HAMR assessments use the Air Force approved audio file, whose timing is not published.

How does scoring work?

Your score is written level.shuttle, for example 9.4, the last shuttle you completed. If you think the result is one shuttle off, correct it by plus or minus one shuttle on the result screen. The result also shows shuttles, distance and time.

How is VO2 max worked out?

VO2 max is an estimate from your final speed, for the 20 m tests only. For ages 8 to 17 the app uses the Léger 1988 youth equation; for adults it uses Léger and Gadoury 1989 (6.0 x speed - 27.4). Set your age in Settings; if you are under 18, set it so the youth equation is used. It is an estimate, not a medical measurement.

Safety

The beep test is a maximal effort. Warm up first, run on a flat, non-slip surface, and stop if you feel dizzy, in pain or unwell. If you have a health condition, ask a doctor before testing.
