Beep test

Hi guys!
I'm looking for app for beep test (or in the full name: Multi-stage fitness test).
someone are wrote about this...but I didn't see some helpful reaction.
the "beep test" is one of the most popular test/activity and it's look pretty simple to develop an app for this/
I try to learn about how to work with the software but without no success:(,
so thank you a lot...

I'm also interested in something similar. A couple of days ago my edge 520plus landed elsewhere after a crash and I could not find until it beeped when connected back to my smartphone. I was wondering whether it is difficult to implement an app for any of the devices to make the edge beep continously until pressed a button, a sound that one can trigger remotely from the smartphone to help find the lost device in the middle of the grass. Is there anything like this?

I would like to develop it but I'm new to the development of apps/widgets for Garmin. Thanks
