This was an awesome app. Simple, easy to use. And I’d give it 5 stars if the developers hadn’t “improved” it. Now I have to remove all the zeros from the readings input boxes before I add my readings because I now can’t overwrite the zeros, they just stay there along with my added numbers unless I delete them first. 2nd issue is when I tap the plus for new reading, it opens my last reading rather than a blank new one. At first I thought I was accidentally tapping previous reading but tonight I carefully tapped the plus and, sure enough, it displayed this mornings readings, not a new “blank”. So what used to take a total of 4 steps (from tapping the plus for new, to entering numbers in 3 boxes) now takes a minimum of 9. How is this an improvement? Have you ever heard “if it ain’t broke, don’t fix it?”
