Metric and Imperial

This app offers a simple interface to calculate BMI with inputs in either kg-cm or lb-ft-in. I use it at work many times per day. I just tried this update 2.0 and it seems to still work fine. My only suggestion would be that sometimes I have patient info available partly in metric and partly in imperial (e.g., 174cm, 200pounds) and this app doesn't allow mixed inputs. Sure I can convert, but that's another step many times per day. Also there is a small advertisement across the top in the app, but not on the screenshot on the App Store.

I used the free version for years and loved it. It had ads that showed on the perimeters but that was fine, it didn’t obstruct the view. Today I opened the app and a ratings box popped up. I have previously rated the app on several occasions and I get annoyed when any app asks you to evaluate it more than once or maybe once per update. So I gave it 5 stars to get out of the eval process but I left no comments. The ratings box disappeared and I started to enter the first value when an ad banner popped up RIGHT OVER THE VALUE INPUT so I could not use the app. I tried to adjust the ad so it was not interfering with the normal function but I could not relocate it. So I got out and deleted the app and re-installed from the App Store but I got the same results. So I will NOT recommend this app to anyone. I would have given a lower rating but the least you can give is one star. It’s so sad because I really liked the app until the changes were made.

This app doesn’t track BMI over time, include age in the calculation, or shine your shoes. On the other hand, it also doesn’t use sliders that won’t stay put or include pop up ads that obscure what you’re trying to look at. It’s just simple, easy to read, and by golly, it works.
