Variant on "first app" - gym timer, in binary

Great! I think that's fine... By default setWatch only calls the function once, but you can have more than one setWatch active on a button at once.

Maybe the best option is to put setWatch(function, button, {repeat:true}) right at the end of your code outside the function, then you have something that is called whenever you press a button, and in the function that's called you work out what to do?

I don't think there is a tutorial for settings at the moment - but I'll have a go at getting one done later today. If you want to get started quick I'd look at gadgetbridge as an example: https://github.com/espruino/BangleApps/t­ree/master/apps/gbridge

You just create a settings file in that format, and put it on the bangle as myapp.settings.js and you're done.
