great but
I’ve been using this for a few years, I’m hopeless at maths, so it’s really useful when it comes to adjusting flour / water ratios when I bake. However a bug has crept in somehow, I think it occurred when I changed my ipad mini from gen 4 to gen 6, the symptoms are…. at the bottom of the screen the row of symbols 0 _ +/- Done are only half visible ( only the top third) and therefore difficult to select, it takes several jabs.
