Try a parable, you know the one about teach a man to fish versus give him a fish . . . .

@Tentman Is that the one where you give him fish and he eats for a day, Teach a man to fish and you get rid of him for the weekends.........Or as my wife would say..Teach a man to fish and he will want to buy a bigger boat...

Does GRT work on android? I tried dowloading it to my phone but it can't seem to get it to run.
If not, is there a goid android equivalent?

I use it on my desktop.
I'd be surprised if it worked on a phone. Quickload definitely doesn't and came on a CD.

I've got the free 'strelok' on the fone. Basic but goes good.

GRT isn't a drop chart type app its an application that calculates muzzle velocity based on case design powder charge seating depth projectile etc.

It's for reloading

A consideration with (weak) rimfire casings might be to have peak pressure over and done with before the case-supporting bolt face moves too far back.
