I was having some difficulty getting the shooter app on my phone to work with my S&B scope which has 1cm@100m turrets. Anyway after frying my brain trying to work out how many MOA at 100m that one click would equal I found this article. I hadn't realised that Milliradians were metric! Doh!
Easy now, set the elevation and windage settings on the app to 1/10 and set the unit to mills and hey presto it should be accurate now....
Sorry if I am teaching granny to suck eggs here, maths was never my strong point.
