Thanks for the interest in this topic, it seems we have a general dislike of the Android Calculator but there are heaps of calcs in app land and I'm sure we can all find one that does most of what we want.
Andrew, you obviously have a better camera on your phone than mine - Useless on close up no matter which way I hold my mouth. And I do hope you don't have sheep on your shop. (Well not too often.)
John R and CrazyMod That's a use I have not heard of before but I reckon there are thousands I have not heard about.
Joules, I guess you need the volume well up then? zzzz
Komatias, I have heard of FS wiz in conjunction with CNC which I don't have.

Sparky, I downloaded TapDrillTool for a play with. But, being me I will probably just reach for the printed chart I have used for yonks. Kijiji, a bit far to travel from OZ,
RussellT No, not off topic at all, we are talking phone apps that we find usefull - or otherwise. Army Knife app looks worth a download and play with too.
Thanks all, lets see where this goes next.
