Tormek Angle Calculator- URGENT

[Peter Eaton]

Hopefully someone can help with this.

I have always used the angle calculator which I purchased off the guy who passed from Knife Grinders Australia, I think he was called Vladim? I had the app saved on two Ipads, one was lost on an update the other I cannot us as the Ipad just died, I have the program on my laptop but the program will not open now..... 😳

I need a calculator urgently with a few hrs hopefully as have knives to grind to various degrees and want them accurate. Does anyone know of a decent calculator that calculator that will work on a Mac, Iphone and Ipad please...or failing this a Windows PC as I have both.

Looking for the easiest to use as had one I bought off the Appstore which for the life of me I could never figure how to use 😳...

Thanks in advance
