Always been useful, but – iHandy Carpenter Review

I've had this app on my phones for a long time but I just tried to use the ruler on my 7 (non-plus) and it is definitely off (inches are too large). The last version update claims it was modified for 6s/6s+ and large screen phones, but maybe iOS 10 broke it. Devs, can you please fix the ruler? Thanks.
