OK, confirmed it works on iOS 10.
Pinch zoom is better now, it's more intuitive. It's still difficult sometimes to move a zoomed in section of trend to the middle of the view port. I think this is because the scrolling is bounded by the limits of the zoomed out view, so if part of the trend is near the outside border then further scrolling is blocked in that direction.
I think that on a bigger screen some of the text is quite small and needs a scaled font so it doesn't appear so tiny at higher resolutions. Especially applies to < Settings > < Maths > [ 0 ], but the other blue text could also be larger. (See screenshot attached.)
I still wish for a way to pause and resume data acquisition, and a way to adjust the sample interval.
But overall, looking good. I do like the way you can control the meter from the app.
(By the way, in the attached screenshot, I am not sure what the "686.7 m" is for at the lower left corner of the chart? It is not temperature, and it does not appear to be time either.)
