Why do loops crash?

MIT App Inventor Help
24

Hello There!
I am making a Metronome App because I find there are too much of ads and pretty less room for customization in others. I need 2 things:-

  1. A sound effect for a metronome.
    AND
  2. A loop that won't crash (while loops crash when they are set to infinite).

Regarding the original post of how to run an infinite loop. the general idea is to use a global list as a work queue, driven by a fast Clock Timer.

Here are some projects that run forever like that ...
